Did centos 5.1 do something different than the Red Hat on which they were based? the Red Hat 5 /update 1 is still claiming to have xen 3.0.3 and 32-bit guests on 64bit dom0 as a "technology preview", i.e. it doesn't work yet,. If anyone does have that feature working on either redhat or centos, let me know. Steve ------------------------------------------------------------------ Steven C.

The HVM support in 3.1 is much improved from 3.0.3 (as evidenced by Redhat now talking about Windows guests, IIRC).

On three out of four of the servers I've tried, I will get a total system (dom0) crash when trying to start a fully virtualized domU. I will run `xm create xen_test`, it will start, then return to the command line, but invariably within five to ten seconds the entire system will freeze. I get no error messages to any of the logs, or anything output to the console. Absolutely nothing responds. I can't find any record of the error after power cycling the machine. The interesting thing is that on one server of the same type out of the four I've tried, it works absolutely fine every time. I've tried moving the hvm image and config to the other servers but those fail as well. There might be some differences in the hardware components used but the servers have the same board and same CPUs, with the same version of Centos and Xen. I did read that some people were having problems with hvm crashing the dom0 a while back on the list when using AMD 64 cpus. I don't know if that would apply to this version of xen or if it might be somehow related, but I thought it was a good chance. Porting xen 3.1 to the kernel-xen RPM is an option, but one I'd really like to avoid if possible.
