Is anyone already working on RPMs for VirtualBox OSE?
by Greg Bailey 13 Nov '07

13 Nov '07

I have some RPMs I've made of innotek's VirtualBox OSE (Open Source Edition) for both CentOS 4 and CentOS 5 (i386). These RPMs include the dkms support for the kernel driver, etc. I have a couple of subtle things to fix in the RPMs (like setting the permissions on udev devices, etc.) but they're already usable. Before I spend more time on it, and submit it for inclusion in the "testing" repo, I thought I'd ask here if someone was already working on doing this. thanks! Greg Bailey gbailey(a)lxpro.com

kvm in testing
by Farkas Levente 19 Sep '07

19 Sep '07

hi, in testing the kvm version is kvm-kmod-36-2.2.6.18_8.1.1.el5.src.rpm shouldn't it be 36-2.2.6.18_8.1.10 or at least 36-2.2.6.18_8.1.8? it has reason or just a bug? thanks. -- Levente "Si vis pacem para bellum!"

KVM-36
by Daniel de Kok 15 Sep '07

15 Sep '07

Hi all, KVM-36 is now in testing. Since KVM-37 has added new functionality (pic/lapic/ioapic) that could introduce regressions, this is the release that we will stick to (testing, extra if there are no serious regressions compared to kvm-35) for a while. Take care, Daniel

Xen VMs on GFS
by Lars E. D. Jensen 10 Sep '07

10 Sep '07

Hello list I've installed cluster suite with 8 physical nodes, these are connected to a SAN using CLVM and AOE protocol. The cluster suite runs on the physical nodes/servers, in dom0. If I have to use GFS, where do I install this? What is the right approach to using GFS with Xen. I see 2 options: 1. I install GFS inside each domU (unprivileged domain, the actual VM). 2. I install GFS on CLVM volumes on dom0 and mount these partitions with domUs. Which of these options are possible ? Or maybe I have to ask, how do you do it ? :) Thanks Lars

rpms for kvm on centos
by Farkas Levente 10 Sep '07

10 Sep '07

hi, for those of you who can't wait for the centos testing rpms i recompile a few packages for centos-5: https://www.lfarkas.org/linux/packages/centos/5/ there's no support for it and the centos repositories are always better then these packages:-) -- Levente "Si vis pacem para bellum!"

Host crash bugs are > very important to fix especially one so easily reproducible. yes, when c5-testing will include kvm-36. i already recompile many rpms to be able to use the latest tools, but since kvm is in centos-extras i'd rather stay with that and don't mix packages. -- Levente "Si vis pacem para bellum!"

qemu 0.9.0 in c5-testing
by Daniel de Kok 08 Sep '07

08 Sep '07

Hi all, A package for the qemu machine emulator/virtualizer is now available in CentOS testing for CentOS 5. qemu was added - Because the package contains qemu-img, a handy tool for creating and converting disk images (e.g. for KVM). - For full virtualization on i386 and x86_64 CPUs that don't have VT-X or AMD-V support. kqemu is required for optimal performance, we plan to provide a module package for kqemu in the near future. For the moment, testing can be oriented at using this (qemu-img in particular) in combination with KVM. Once the kqemu module packages are ready, we are also interested in qemu + kqemu testing results. Information on using the CentOS Testing repository can be found on the CentOS Wiki at: http://wiki.centos.org/Repositories Take care, Daniel

(long) kvm and virt-manager not ready for daily usage
by Farkas Levente 08 Sep '07

08 Sep '07

hi, in the last 2 weeks we play a lot with our new server which we but to a our virtual server for the development and collect some very subjective experience. we use kvm and virt-manager, but sometimes i'm not really sure about the whether it's kvm or virt-manager problem so i collect them together. our system: MB: Intel S3000AHV CPU: Intel Core 2 Quad CPU Q6600 @ 2.40GHz RAM: 8GB CentOS 5 x86-64 host system with: kernel-2.6.18-8.1.8.el5 kmod-kvm-35-1.2.6.18_8.1.8.el5 kvm-35-1 libvirt-0.3.2-2 libvirt-python-0.3.2-2 python-virtinst-0.300.0-1 virt-manager-0.5.0-1 virt-top-0.3.2.5-1 virt-viewer-0.0.2-1 kvm is not ready for production use for many reason: it can't reboot which imho a very basic feature, what's more can't even shutdown/poweroff. the centos i386 guest are not able to shutdown on the x86_64 host (strange the x86_64 centos and the i586 mandrake-9 are able to shutdown) or what's seems to be more likely it's a random think. can't give 2GB ram to any guests not even 2, but 1.9999 is ok. what's more i've to discover this in the hard way virt-manager gives some strange error message (anyway none of the virt-manager's error message are useful, just strange stack trace without any kind of useful info). the host see as i've 4 cpu. i've got a change to gives more cpu to the guest, what's more they starts, but after a few minutes running the system crash. not just the guest os but the host os crash without any kind of info, log or any useful info what was the cause of it, but hard reset helps:-((( first of all it's serious problem, even if it's a known bug and documented somewhere (but there is not any kind of docs about neither kvm nor virt-manager/libvirt and what i can find that very limited), since all of the new hvm cpu (which is required for kvm) has more core, so the guest can't use the real power of the cpu this means i've to put a lots of guests with one virtual cpu to the host or currently can't exploit these cpus. libvirt not start the guest when the host started, not saved the state of the guests when stopped, when restarted all guest get into shutdown state. may be it's just libvirt but, but if kvm not able to save it's guest's state that it's a real pain. this behavior not acceptable in a real environment. in virt-manager can't modify virtual cpu number of the guests (virt-manager crash with another unusable stacks trace). it i modify the xml config file by hand i've to restart libvirt in order to read it. even if i just modify one guest's config, but as if i restart libvirtd the all other guest will be killed it's another nice feature. from vit-manager i can't assign swap partitions (and any other device to the guests) during guest creation. i precreate lvm partition on the host for root and swap to all of our guests (about 10) but it's a real pain to reload libvirtd (which kills all guests) to add a new disk to the guest which can be used as a swap or other partition. what's more it'd be useful to add swap partition during install. the same thing apply to cdrom too. if i made a mistake in the libvirtd xml config file, then i don't get any kind of error message just libvirt don't start the given guest. no error message service seems to start without error and don't know what was the reason that the guest not start (sometimes because syntactic error in the config file, sometimes kvm/qemu not support it eg more then 2gb mem). there are unwritten unix/linux tradition eg if there are error during a service startup report it some log file. if a service can't start without error then it not start at all eg. if i've apache with 5 virtual host but one of it's config has error then the whole httpd not started. it'd have to be the same with libvirt too. libvirt config file has all the features as qemu command line (if not it can't be used by advanced users)? but i don't know since there is not a reference docs for the config file. there is not a detailed reference docs about libvirtd config (and at the same time the gui not contains all the settings). for the the xml format is a bit redundant eg. "source dev", "target dev" why not just source and target, inside interface type='bridge' 'source bridge' why not just source (i've to modify two place when i'd like to switch from network to bride. ok these are just small cosmetic thing just mention. when create a new guest in virt-manager and reach the last page and press finish then most of the time (2 times from 3) i've got an error something like "can't connect to qemu" after i press ok and press again finish then it's able to create the new host (so always have to retry it). in virt-manager when a guest is shutdown and double-click on the guest and try to start it it's not possible. you've to select the guest in the main windows, right-click and start it. the new vnc based console is very unstable or just virt-manager not able to connect it. many times i double click on a guest in virt-manager i got the window can't connect to console while the guest are running. that's why i like to see again the serial console. we've got other virtual servers with xen and openvz, with has other problems but works. my conclusion is that currently kvm, libvirtd, virt-manager (et-mgmt-tools) seems very promising. but currently just in a very alpha stage using even in non mission critical but production environment still a very 'brave' decision. xen has a few years vantage, but it's at least usable in real environment. i'm on the these list and see what kind of problem you're working which is great but at the same it'd be useful to fix the most basic problems with these tools. just my 2c to these community. -- Levente "Si vis pacem para bellum!"

Virtual Box: br0 not resolving: No DHCPOFFERS

Dear Centos-Virt: Help! Guest=XP Pro, SP2 Host=CentOS5; # uname -r; 2.6.18-8.1.8.el5 VirtualBox-1.4.0_21864_rhel5-1.i586 http://www.virtualbox.org/download/1.5.0/VirtualBox-1.5.0_24069_rhel5-1.i58… I have two nic: eth0 is the internal network; eth1 connects to a DSL modem. I also have a fully functioning DHCP server on eth0 (works perfectly with Parallels for Linux). The directions (from hell): http://www.virtualbox.org/download/UserManual.pdf I am trying to set up a "host interface" network between my XP guest and my Linux host. Three problems: 1) "br0" does not resolve with my DHCP server: "No DHCPOFFERS received" 2) Virtual Box will not start, unless I switch to no network or NAT network 3) eth1 will not communicate with the Internet after restarting the network daemon to try to bet an address for br0 Following the directions on page 62 for Fedora Core in the users manual do not work (or I am doing them wrong): 1) # chmod 0666 /dev/net/tun 2) /etc/sysconfig/network-scripts/ifcfg-br0: DEVICE=br0 TYPE=Bridge BOOTPROTO=dhcp ONBOOT=yes 3) /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 TYPE=Ethernet 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 IPV6ADDR= IPV6PREFIX= ONBOOT=yes USERCTL=yes IPV6INIT=no PEERDNS=no BRIDGE=br0 4)# sudo /sbin/service network restart br0 failed: FAILED, unable to resolve IP address.

hi, i've got a centos-5 x86_64 kvm-35 host system with one centos-5 i386 and one x86_64 guests. but none of the guest are able to restart. ie. i login to the guests and restart it. it start's as normal reboot, but after the last command (shuting down md device) it's do nothing, but in virt-manager i see 50% load on the guest. the biggest problem currently i can't find any way to restart any guest's other then shutdown and use virt-manager and restart them:-( what can be a problem? is it a known bug or it's just not working for me? thanks in advance. my system: kernel-2.6.18-8.1.8.el5 kernel-headers-2.6.18-8.1.8.el5 kmod-kvm-35-1.2.6.18_8.1.8.el5 kvm-35-1 libvirt-0.3.2-2 libvirt-python-0.3.2-2 python-virtinst-0.300.0-1 virt-manager-0.5.0-1 virt-top-0.3.2.5-1 virt-viewer-0.0.2-1 -- Levente "Si vis pacem para bellum!"

Xen Minimal images for CentOS 4 and 5 x86_64
by Karanbir Singh 02 Sep '07

02 Sep '07

Hi, A while back I had created some minimal Xen images for centos-4 and centos-5 on x86_64 paravirt under a c5 x86_64 install. The images are at : http://www.karan.org/mock/Xen/ root account password for these images is : p4s5w0rd Feel free to look and use/abuse as you like, yum is completely functional within the images and its recommended you do a 'yum update' as soon as possible. If we can standardise on a packageset, these images can be built at the time we do a distro update. And can be done for all Arch and Versions that support Xen. -- Karanbir Singh : http://www.karan.org/ : 2522219@icq
