That's the first thing we did. It's a Supermicro with an X8DTU-F board, updated to bios version 2.0b (which includes the latest microcode). The procs are Intel 5620's > When you say "suddenly", this was with no changes to software and hardware? The host software and hardware hasn't changed in the two months since the machine has been running. 2.6.34.7 kernel and qemu-kvm 0.13. We host customer vms on it though, so virtual machines come and go. Various operating systems, a mixture of Linux, FreeBSD and Windows 2008 R2. We have other machines with the same config without these problems though. > Is cooling adequate? Yes. > How much memory is on that machine?
