KVM/libvirt VM reboot support didn't come along until relatively recent, in libvirt 0.9.3. Prior to this Nimbus' attempt to reboot a KVM VM would result in an error from libvirt that caused the VM to be considered CORRUPT:
File "/usr/lib64/python2.4/site-packages/libvirt.py", line 392, in reboot
if ret == -1: raise libvirtError ('virDomainReboot() failed', dom=self)
libvirtError: this function is not supported by the hypervisor: virDomainReboot

If possible Nimbus should catch this error return it to the user, but leave the VM in a healthy state.
