[one-users] fast recovery after onevm suspend (fwd)

[Steven Timm]

We frequently use onevm suspend to save the state of all the virtual 
machines on a VM host before we reboot the node. Only problem is, nothing 
is there to tell the ntpd daemon that it should restart once the VM 
resumes. It stays running through the suspend and resume but it is too far 
out of time sync to bring the virtual machine back into time.  We have 
also seen clock skews like this in cold migrate mode.

Has anyone come up with a hook in the resume process to send a signal to 
the VM to resynchronize its clock?
