[CentOS-virt] DomU Guests not shutting down nicely when Dom0 Hypervisor shuts down

[Keith Roberts]

Hi Francis.

Personally I would gracefully shutdown all the VM’s first, before attempting to shutdown the xen hypervisor.

Are you getting any fsck errors when restarting those VM’s?

Kind Regards,

Keith
