Unfortunately for this investigation I managed to upgrade BIOS version few months ago. I just checked - there are no newer versions. I do see, however, that many people advise to change to acpi_pm ckocksource (and, thus, disable nohz option) in case similar problems are experienced - I did not invent this workaround (got the idea here: http://forum.proxmox.com/threads/5144-100-CPU-on-host-VM-hang-every-night?p=29143#post29143 ). Looks like an ancient bug. I even upgraded my qemu-kvm to version 0.13 without any significant changes to this behavior. It is really weird, however how one guest can work fine, but two start messing with each other. Shouldn't there be some kind of isolation between them? As they both start to behave exactly the same at exactly the same time. And it does not happen once a month or a year, but pretty frequently.
