What I notice is that if the VPS's are "suspended" which appears to be 
the first option that will be attempted in a reboot of the node, they 
will not boot into the new kernel themselves.  Not to mention the delay 
in the shutdown process (can take a LOOOOONNNNGGGGG time).

Therefore, what I have been doing in order to speed up the process is 
issue a shutdown for all the virtuals, then issue the reboot.  This can 
be done in a one-line like this:
for VE in $(vzlist -Ha -o veid); do vzctl stop $VE; done && reboot
