Hi Dejan, thanks as usual for your response. In the end, since that I was facing too much unexplainable problems I decided to upgrade libvirt and the kernel itself to a newer version (from squeeze to squeeze-backports). Until now problems seems to be resolved. In Pacemaker Explained (Andrew, I'm almost finished with the translation, I swear!) it is written that the default action on fail is "fence", so it is assumed that if a single resource fails, then the entire node is fenced. Note that at the moment every of my virtualdomain resource have got the on-fail action set with "restart", and I've not faced any fence. But please, help me to understand this: what do you mean with "subsequent stop operation"? It is very plausible that this was the reason, since the failed virtual machines were in state "paused" even if I was forcing the stop. Does this is enough to make a node fence? Why this failure is not considered in "on-fail" parameter declaration? Do I made myself clear?
