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

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
