Hello list, I encountered two Windows Server 2003 Std SP1 guests which would randomly hang with 100% CPU after several hours of normal operation. The guest would not respond at all, not even to ping requests. Its process on the host uses 100% CPU.
The Host: Dual-Core AMD Opteron(tm) Processor 2212 10GB DDRII RAM Linux 2.6.24.3 KVM-63 userspace Other KVM guests (Linux and Windows Vista) are rock-solid The two problematic guests: Imaged from VMWare ESX 2.5 with reinstall of the ACPI Uniprocessor HAL and drivers. Switching to the Standard PC HAL and using -no-acpi does not help. Tried with the new virtio NIC first and changed to ne2k_pci later but no effect. One guest uses a raw hard disk image the other qcow2. The guests are launched with this command-line: kvm -hda bonus-system.qcow2 -m 1024 -net nic,model=ne2k_pci,macaddr=52:54:00:74:A1:0C -net tap,ifname=vm-bonus -vnc 10.73.250.1:2 -k de -monitor tcp:10.73.250.1:5952,server,nowait -localtime Currently I'm testing with a fresh install of Win2003 STD SP1 to rule out the imaged-from-ESX factor. Also I'm running one of the machines with -no-kvm now and will report back how that works out. Any idea how to go about debugging this? Also I see interesting syslog entries. But they don't seem directly related to the hangs, as the times do not match.
