1)
Can you eleborate a little bit on this (my current plan is to LU Dom0
from snv_b98 to snv_b124 in november, DomUs: Win SBS 2003 32bit,
Win STD Server 2008 32bit) ?

2)
Is it possible, that the PV driver gets loaded very late, i.e. after 
Win 2008 Std Server has done its filecheck? If so, is it possible to
force it to load earlier?

Background: Had a prod server, which was not accessible via RDP. 
virsh list and xentop reported that this DomU is running for ~20s,
after that 'no state' for ~2-3s and than running again. During the 
'running' phases CPU usage was between 25-120% (I guess, it used 
only a single core - 4 are assigned to it). So connected via vnc
and it showed, something like:
3 Prozent abgeschlossen. (35850 von 95360 Datensaetzen verarbeitet)
in english - I guess it would be
3 Percent finished. (35850 of 95360 datasets processed)

At this time each dataset check took about ~1.67s !!! Since I was
wondering,  what comes next, I let it ran further 27 !!! hours. Than 
it startet to check ~ 150K indexes at the same speed (saying 11% finished).
And this was the time, when I decided to rollback to the previous snapshot
(more than a day without a redundant server for more or less mission
critical stuff is a little bit too hot IMHO ;-)).

So actually it seemed to be very odd. The server uses about 20 of 24GB zvol.
Since it happend a 2nd time within 3 month, I guess, beside Windows
the PV driver could be a problem as well ...

So any hints?

Regards,
jel.
