I had the same problem on a previous server. I ultimately replaced the CPU and I think that solved the problem.

However with this one we are running these domains: Name ID Mem(MiB) VCPUs State Time(s) Domain-0 0 2307 2 r----- 4520.9 mars 10 1511 1 -b---- 174.0 monitoring 14 229 1 -b---- 12.1 The problem we are experiencing is after about an hour the servers do not respond. We have to do an xm destroy and then create to get them to work again. Is this a known issue and what could be possible fixes for the problem?
