[CentOS] Rebooting CentOS 5.2 XEN Guest

All,

I have CentOS 5.2 XEN guests running on a CentOS 5.2 host.

At one time when I issued an 'init 6' in one of the XEN guests it rebooted Now it seems to halt but virt-manager shows it as still running and the only way to get the guest to boot is to destroy the virtual machine and start it again.

Unfortunately I didn't notice precisely when this change in behavior occurred, I believe it was the last 'yum update' that included a new XEN kernel, but I cannot say for sure.

Has anyone else noticed this change in behavior? Any solutions to restore the older behavior, being able to 'init 6' the virtual machine was very useful.

Thank you,

Brett
