for linux VM, I never had issue even if pv driver are well out of 
datedate. However for Windows I had a few win2k3 vm crash after 
migrating from XCP1.1 to XCP1.6 where the driver was not yet updated 
(different vms on different xen servers with different applicative 
workload) . So I'd say it is better to update, even if in most case it 
is not technically necessary.

it is not yet a big enough PITA for us, so we have not yet automated the 
process. However we are using a WAPT 
(http://dev.tranquil.it/index.php/WAPT_-_apt-get_pour_Windows , sorry 
French only..., disclaimer : I work on that GPL project) for similar 
windows automation stuff, so we may use it one day for that purpose.

cf above, mostly working, but beware.

I don't know about this one, when we had issue with the win2k3 virtual 
machines, we had BSOD, so not much debug to gather unless you enable 
serial console I guess.
Cheers,

Denis
