Open VPN connection problem on Virtual Box
by Todd and Margo Chester 02 May '08

02 May '08

Hi All, I am working on a mystery. I am using openvpn-2.1_beta7-gui-1.0.3-install on all the computers in question. All computers are running XP-Pro-SP2. (Mine is running in a virtual window -- details below.) This configuration works perfectly from my office. I use it to call five facilities: remote aa.bb.cc.dd port 5030 proto udp dev tap ifconfig 192.168.240.30 255.255.255.0 secret iamnottellingyou.txt ping-restart 60 ping-timer-rem persist-tun persist-key resolv-retry 86400 ping 10 comp-lzo verb 6 mute 10 But, this EXACT config works on TWO other computers, but not mine: remote ww.xx.yy.zz 5020 client dev tap proto udp resolv-retry infinite nobind persist-key persist-tun ca foo-ca.crt cert foo-client1.crt key foo-client1.key ns-cert-type server ping 10 comp-lzo verb 3 The only difference between the two computers that MY config works on and mine, is that my computer is running in a virtual window. Host: Cent OS 5.1 Guest XP-Pro-SP2 VM: VirtualBox-1.5.6_28266_rhel5-1.i586.rpm The host and the guest are connected by a bridge (br0): DEVICE=br0 TYPE=Bridge BOOTPROTO=static BROADCAST=192.168.255.255 IPADDR=192.168.255.10 NETMASK=255.255.255.0 NETWORK=192.168.255.0 GATEWAY=192.168.255.10 ONBOOT=yes USERCTL=yes IPV6INIT=no PEERDNS=no PROMISC=yes When trying to connect, the same error message pops up on my computer (virtual XP) and on the distant end's (XP) server: TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity) The SAME error message! Why does the first config work, but not the second? It is obviously not the config: it is identical on the other two computers that it works on. I think it may be the way open vpn is reacting to my bridge, but then, again, the first config works. Editorial comment: AAAAAAAAAHHHHHHHHHHHHHHHHHHH!!!! Anyone know what I am doing wrong? Many thanks, -T

Instalation Windows XP to XEN(Dom0 is CentOS 5)
by Pavel Muller 30 Apr '08

30 Apr '08

Hello, I have problem with instalation Windows XP to XEN(Dom0 is CentOS 5). XEN is in last version for Cent OS 5(I am not sure but I think that is 3.0.4). CPU is Intel C2D with virtualization support. During the wizzard I chose FULLY virt. Windows was installed from ISO image to IMG file. During the installation appeared the dialog box with message: asms file is needed, insert please instalation CD. In virt-manager I added CD (CD is all right), but this action was without effect. Can you help me please? Do you have experience with "XP to XEN"? Regards Pavel

virt-install error messages
by Kai Schaetzl 29 Apr '08

29 Apr '08

I get two errors when doing a fully automated kickstart install with virt- install: > libvir: QEMU error : connect: /var/run/libvirt/qemud-sock: Connection refused > libvir: warning : Failed to find the network: Is the daemon running ? that seems to be harmless and is caused by libvirtd being shut off. Then I get: > Starting install... > libvir: Xen Daemon error : GET operation failed: > Retrieving CentOS... 194 kB 00:00 > Retrieving vmlinuz... 2.0 MB 00:00 > Retrieving initrd.img... 5.0 MB 00:00 > libvir: Xen Daemon error : GET operation failed: > Creating domain... 0 B 00:00 > Domain installation still in progress. You can reconnect > to the console to complete the installation process. The "GET operation failed:" error seems to be harmless, too, but it happens whether libvirt is running or not. From googling around it looks like this is a pretty standard error. Could this be a bug in virt-install? Apart from that I notice that the virt-install installation seems to be more ressource hungry than starting a kickstart installation with virt-manager. While I don't recognize much of the virt-manager installation performance-wise, the virt-install installation clearly drains on the CPU, the system reaches 100% CPU utilization during the first one or two minutes and that is noticable at least on the desktop.

Xen networking - pulling out my hair
by Ken Bass 29 Apr '08

29 Apr '08

I just cant get a Centos 5.1 domU to install under Centos 5.1 dom0. It is maddening! I'm trying to replace a single server that currently uses simple ethernet aliases (eth0:0, eth0:1, etc) with a new server that uses Xen virtualization. Maybe I dont understand bridging properly or something. My dom0 has the following: eth0 Link encap:Ethernet HWaddr 00:00:44:11:22:33 inet addr:192.168.144.6 Bcast:192.168.144.7 Mask:255.255.255.252 Notice that it is a 192.168.144.4/30 address. That is all I have for my dom0. I want two different domU's. All the examples I see online have /24 ranges. domU #1 will be a single 192.168.139.4 domU #2 will be a subnet of 192.168.139.128/29 At this point that domU will be using 139.129, 130, and 131. The router that I am connected to routes/forwards those subnets to my dom0. At this stage I have modified xend-config.sxp and changed a line to (network-script /bin/true). This was based on various postings telling people to let Centos handle things instead of Xen. A also did the following: ifcfg-eth0: DEVICE=eth0 BOOTPROTO=none NETWORK=192.168.144.4 NETMASK=255.255.255.252 IPADDR=192.168.144.6 GATEWAY=192.168.144.5 ONBOOT=yes Type=Bridge ifcfg-xenbr0: DEVICE=xenbr0 ONBOOT=yes BRIDGE=eth0 DELAY=0 HWADDR=00:00:44:11:22:33 One problem with this is that eth0 comes up first and complains: Bringing up interface eth0: Device eth0 does not seem to be present, delaying initialization. [FAILED] Bringing up interface xenbr0: [ OK ] So I ended up adding ifup eth0 to /etc/rc.local. What a hack. If I tried to swap xenbr0 and eth0 files (like some online examples) there are complaints about bridging operation not supported. At this point, am I supposed to do anything special? I just run virt-manager and for shared network it only shows me eth0 (shouldn't it be xenbr0 - since they are bridged, maybe it doesnt matter) In anaconda, I select manual/static IP address. I enter 192.168.139.4 with subnet mask of 255.255.255.255, gateway/ns of 192.168.144.5 (my router). On the next screen anaconda says that it cannot find my stage2.img. When I look at my server logs and even with tcpdump, anaconda is not making any attempt to fetch this file despite the 'unable to retrieve.' message. So there must be some networking issue between the dom0 and domU. I just have no clue. The only attempts I see via tcpdump is if I try to select DHCP server, I see the broadcast packets. I'm not running selinux and I've tried disabling iptables as well as using 'iptables -I FORWARD -m physdev --physdev-is-bridged -j ACCEPT' Initially from reading I thought I may want a 'routed' xen setup instead of bridged, but it seems none of the tools virt-manager, virt-install, koan, etc support 'routed'.

RE: [CentOS] dd trough scp with tar
by Joseph L. Casale 26 Apr '08

>First, I'd expect some problems with the device drivers when you try to >restore a vmware image onto a xen virtual environment - unless they >present similar virtual hardware. Actually, your lucky on this one. Windows *always* loads an ide driver into the Critical Device Database unless you explicitly tell it not to with an installation answer file, or remove it after install. >However, for the actual copy operation, I'd recommend clonezilla-live >(http://www.clonezilla.org/clonezilla-live/).

The advantage >over dd is that it knows enough about ntfs and most linux file systems >to just save the used blocks and when you restore it will let you pick >from the list of images you've saved. Yup, did the same thing recently with WinPE 2.0 and Ghost (Same internal concepts, faster then dd and ssh/cp) when moving off an ESX server into Xen 3.2. jlc

dd trough scp with tar
by David Hláčik 25 Apr '08

25 Apr '08

Hi, first i will explain my experiment : We have ESX server running virtual machines .We want to migrate to XEN. As i did not found any tool for transfering ESX to for example real server, or better to XEN --> please correct me if i am wrong , i found following approach : i will inside virtual machine on ESX boot from Live-CD of CentOS , using dd i will transfer images trought scp to CentOs machine with xen. I believe this one should work, machines on ESX are Windows2003 Servers. So what i need to find is how to write a command which will transfer image trought scp , but for faster transfer also compress it before using tar, or gzip. *so my input will be dd if=/dev/sda1 , my output will be gzipped or tarred image on second side. sda1.img.gz* ** Thanks in advance! D.

32-bit Centos 5.1 kickstart hangs on xen domU HVM installation
by Dave Nash 24 Apr '08

24 Apr '08

I am trying to a install Centos 5.1 32-bit Xen HVM DomU onto a Centos 5.1 64bit DomU with the default xen installed and the kickstart hangs at random points during the install process. Sometimes retrieving the image, sometimes formatting the filesystem, sometimes installing the packages,etc. I tried upgrading to xen 3.2 and encounter the same problem before rebuilding back to stock Centos 5.1 64-bit Xen. I am able to use our kickstarts configs to install Centos 5.1 64-bit HVM and Centos 4.5 32-bit HVM on this machine without any problem's. Below is xen configuration and the Centos 5.1 32-bit kickstart Config file I have been using.

Installing old Suse as fully virtualized guest: problem with install source
by Kai Schaetzl 21 Apr '08

21 Apr '08

Using CentOS 5.1 with Xen 3.2. I'm trying to install a fully virtualized system for the first time and doing this with an old Suse 9.0 (this probably would run paravirtualized, maybe it won't run, anyway, because of hardware problems). I start with virt-manager and after choosing "fully virtualized" it presents me two options for install media: iso image and CD-ROM or DVD, but the latter is grayed out. I have the install source on CDs ... Is this normal or do I yet need another patch to make it work in xen 3.2?

Section 3.3 of the 3.0 Xen user guide states Xen can wait for all running guests (pv I assume) to shutdown before it shuts down. What are the requirements for this to work? In a test setup, I made an lvm snap of a CentOS 5.1 pv guest and then shut down Dom0 and it didn't wait for that DomU? Thanks! jlc

Re: [CentOS-virt] Xen List

The silly mistake that always gets me is I forget to put the .img extension on the initrd file, be careful when running mkinitrd that the exact command is: # mkinitrd -f --preload=pciback /boot/initrd-$(uname -r).img $(uname -r) You can remove the pciback stuff from grub.conf, but make sure the modprobe.conf options are there prior to running mkinitrd. -Ross ----- Original Message ----- From: centos-virt-bounces(a)centos.org <centos-virt-bounces(a)centos.org> To: Discussion about the virtualization on CentOS <centos-virt(a)centos.org> Sent: Thu Apr 17 17:03:07 2008 Subject: RE: [CentOS-virt] Xen List >Here's an example using my sound card. > >/etc/modprobe.conf: >options pciback hide=(00:10.1) ># If you aren't preloading pciback in the initrd uncomment the next line >#install snd-hda-intel /usr/sbin/modprobe pciback; /sbin/modprobe --first-time --ignore-install snd-hda-intel > >To preload pciback in initrd: > ># mkinitrd -f --preload=pciback /etc/initrd-$(uname -r).img $(uname -r) > >That should do it. Ok, this is where I got messed up (No grub line :)). I originally had the rpmforge sk98ln rpm installed to make this realtek nic work before I tried this, then using this procedure which I followed to a "t" didn't mask the device from Dom0? It loaded the driver and setup the nic? I know I had the pci slot number right. I thought the initrd was wrong, so I looked through grub and looked at what it loaded, then checked the timestamp of the one I made with that command and it was consistent? I assume something still wasn't right with my mkinitrd, it completed with zero verbosity, mayeb I should try to use -v and see what happens. Any ideas?

How to clone a guest for cold stand by
by Götz Reinicke 16 Apr '08

16 Apr '08

Hi, what would be the shortest and fastest way to clone a e.g. basic Centos 5 guest for further use? For example I'd like to set up a master Mysql-server as a guest an than "clone" two additional slaves. Which xen configfiles may be edited? Can the config and the filesystem simply be copied? Thanks for suggestions!

Compiling Xen from srpm and changing build options
by Joseph L. Casale 16 Apr '08

16 Apr '08

Is it possible to build the rpm from xen's srpm and change options such as whether or not to enable PCI-device backend driver, or basically expose all the options menuconfig would? I am trying to pass a nic into a pv guest and I cant get it to work using the other possible route using the modprobe.conf method. Thanks, jlc

Device 0 (vif) could not be connected. Hotplug scripts not working.

Hi, I got this error when starting a domU on Centos 5.1 i386, Device 0 (vif) could not be connected. Hotplug scripts not working. Why is this happening ? I should restart the machine to see if this still happends after a fresh network bridge. But it's somehow a production server, I would like not to restart it, if possible.

Xen 3.2.0 available in any repository?

Hi folks, Is Xen 3.2.0 available on any CentOS repository or perhaps third party repository? Will using this package require compiling from source? Thanks for your help. /sf

Convirt + CentOS 5
by Alan Murrell 14 Apr '08

14 Apr '08

Hi There, I am currently running CentOS 5.1 with the RPMs that come with the "Virtualization" package and using the virt-manager gui. I really like the look of "convirt" (formerly "xenman") and was thinking of doing the following: - Compile the SRPMs for Xen 3.2 from source and install over top of the existing Xen (I have an x86_64 machine) - Use the latest version of Convirt I was wondering if anyone has done either of the above, and if you had run into any problems? In other words: 1.) What sort of issues (if any) did you run in to when installing Xen 3.2 over top of the the 3.0.3 that comes with CentOS 5.1? 2.) Are you running in to issues using Convirt (I had heard about some issues some users had had trying to using it under CentOS5, but wanted to see of they still persist) TIA for your advice. -Alan

virbr0 and libvirtd
by Joseph L. Casale 14 Apr '08

14 Apr '08

I set libvirtd off to disable virbr0 and set my vif's to point to eth0 as their bridge and this is working well for local connectivity. Are there any ramifications to doing this the way I did? Thanks! jlc

Installing Xen 3.2 from Xen.org under CentOS 5.1 x64
by Joseph L. Casale 11 Apr '08

11 Apr '08

What is the best procedure for doing this on a minimal install of CentOS without a gui? Can I install all the dependencies through yum that a `#yum install xen kernel-xen xen-libs` would bring in, then simply install the xen-3.2.0-0xs.centos5.i386.rpm and xen-libs-3.2.0-0xs.centos5.i386.rpm? Thanks! jlc

xenbr0 isn't created anymore
by Kai Schaetzl 02 Apr '08

02 Apr '08

Somehow I managed to disable the creation of xenbr0 on boot-up of the host system. CentOS 5 with standard CentOS Xen. I changed all Xen VMs to use xenbr0 instead of virbr0 and disabled virtlibd. Works fine. But when I later restarted the machine I found that all networking for guests had gone. On inspection there's no xenbr0 created anymore. I can get it up by stopping network (or eth0) and then running /etc/xen/scripts/network-bridge start xend-config.sxp still has (network-script network-bridge), logging shows no problems. It seems that the network-bridge script simply doesn't run, but why? I can't see any init script or so that might run it, so I assume it's xend doing that, but there's no error in any log.

xm new and plain text config files
by Kai Schaetzl 02 Apr '08

02 Apr '08

After installing PyXML I can now use xen new, but I see it doesn't work like I hoped it would work. It can't read the config files that were created by virt-manager. There is an option -F for using "sxp" config files and I was assuming that might be the correct one, but it's not working either (it always says the file is not there, although it is). Is there a conversion tool or are we supposed to convert manually? Kai -- Kai Schätzl, Berlin, Germany Get your web at Conactive Internet Services: http://www.conactive.com
