The real issue appears to be the message before

"xvda: unknown partition table"

You will have to provide details about your system and setup to get help.

Alexander

Thanks for pinpointing the issue, here is the command line use for domU installation:

virt-install -l http://mirror.centos.org/centos/5/os/i386/ -p -n cent5 -r 768 --vcpus=1 --disk=/srv/xen/mailserver.img --graphics vnc,listen=0.0.0.0,port=5901

Here is my kernel info: uname -a

Anything else info needed?

Thanks,

I guess the disk info may be needed. Do you think the disk info has something to do with the error?

[root@XenTester su]# xm block-list cent5

Vdev BE handle state evt-ch ring-ref BE-path
