Hi,

Please try with only 1 vcpu in the config to see if the problem persists.

Thanks,
Drew

Hello Andrew, 
Thanks for reply.

With 1 vcpu all forks fine.
This bug seems to be present if more than 1 vcpu is defined.

Cool, then I think this is a dup bug 624598. The fix will be available in the 5.6 release. A pre-release test kernel is here if you would like to try it

http://people.redhat.com/jwilson/el5/223.el5/

Please let us know if it works for you.

Thanks,
Drew

It works! Guest reboots normaly even with multiple vcpu in config.

Thanks a lot.

Is there an ETA for 5.6? I don't see any mention of RH 5.6 release anywhere.

Thanks,
