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?
