Web based management system for Xen
by Karanbir Singh 15 May '08

15 May '08

Can anyone recommend a web based management panel that would let me bring up / tear down and do some basic management for a bunch of Xen VM's ? Special bonus points if the panel can manage remote Xen Hosts :D - KB

by David Hláčik 14 May '08

14 May '08

Hi, i am trying to build a custom xen kernel from CentOS source kernel rpm . What i want to achieve is to have custom domU kernel without modules, which will boot domU machine without having /lib/modules . My first try is to simple disable Loadable module support , so i have followed tutorial on CentOS wiki for kernel building http://wiki.centos.org/HowTos/Custom_Kernel . Now it is building, my question is will it work? - again all i have done is to disabled loadable module support. Can someone please point me to sucessfull end? Thanks in advance! D.

tick divider bugs
by Akemi Yagi 05 May '08

Hi all, If you are using the kernel divider= option in your vmware quest, you are probably aware of the bugs reported at: https://bugzilla.redhat.com/show_bug.cgi?id=315471 Someone @redhat "confirmed" the fix is in the test kernel -92. I tried it but it seems to have the same problem as before - when used with clocksource=pit, it hangs on bootup. Wonder if some of you can test this kernel and see how it goes. The test kernel is available from: http://people.redhat.com/dzickus/el5 Akemi

Doubt about compatible hardware
by Waldirio Manhães Pinheiro 03 May '08

Hello friends I was installed the yum group Virtualization to start tests about it, but when my machine was restarted, hung up in same time of start xend daemon .., I'm stoped the daemon with chkconfig and the OS work's fine (without xen), but when I started the daemon, my NIC/Switch led turn off. For recommendation of a guy in #xen channel (irc.freenode.com), I cahnged my NIC and this problem was solved., but every time, my network stop answer .... There are any lists like Hardware Compatible List to Xen ?!, to jump problems like above, where I'll really what NIC I can use. Thank's in advanced. ______________ Atenciosamente Waldirio msn: wmp(a)sinope.com.br Site: www.waldirio.com.br Blog: blog.waldirio.com.br

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
