Re: [Xen-users] My domain crashed :(

[Sadique Puthen <sputhenp@xxxxxxxxxx>]

I assume that you are using the xen packages shipped by CentOS/REDHAT. 
You are trying to install a para virtualized 32 bit guest on a 64 bit 
dom0. Support for 32bit PV in 64 bit dom0 in RHEL/CentOS 5.1is a bit 
broken which has been release documented.
If you have patience, then wait for RHEL-5.2 which supports in a 
reliable way. Or go for self compilation of 3.2 upstream.
