VM hang because of pening interrups not reinjected. |
[Impact]
After the VM(Guest OS is Windows Server 2012R2) has been live-migrated
several times, the screen is blacked out or freeze when the VM is
connected via VNC.
The Windows Guest OS Server has been investigated that all of kernel
threads of Windows Server OS are waiting(idle state) for interrupt
request(IRQ) from hypervisor.
The following environment is tested:
* Host OS: Ubuntu 14.04(kernel 3.13.0-40.69)
* qemu-kvm_2.0.0+dfsg-2ubuntu1.22
* libvert-bin_1.2.2-0ubuntu13.1.5
* nova-compute_1:2014.2.3-0ubuntu1.2~cloud0
* GuestOS: Windows Server 2012R2
* virtio-win-0.1.126
[Fix]
The patch set is needed:
673f7b4257a1 KVM: ioapic: reinject pending interrupts on KVM_SET_IRQCHIP
44847dea7975 KVM: ioapic: extract body of kvm_ioapic_set_irq
0bc830b05c66 KVM: ioapic: clear IRR for edge-triggered interrupts at delivery
0b10a1c87a2b KVM: ioapic: merge ioapic_deliver into ioapic_service
[Test]
Prepare two machines with the same environment mentioned above and run
the following script.
#!/bin/bash
INSTANCE="test"
FROM="elite"
virsh -c qemu+ssh://ubuntu@${FROM}/system list| grep -q ${INSTANCE}
if [[ $? != 0 ]]; then
FROM="dixie";
TO="elite";
else
TO="dixie"
fi
echo "= Migrating ${INSTANCE} from ${FROM} to ${TO} ="
ssh ubuntu@${FROM} -- virsh migrate --live --domain ${INSTANCE}
--desturi qemu+ssh://ubuntu@${TO}/system
The VNC script I use to keep track of the VNC console is:
#!/bin/bash
INSTANCE="test"
while true; do
HOST="elite"
virsh -c qemu+ssh://ubuntu@${HOST}/system list| grep -q ${INSTANCE}
if [[ $? != 0 ]]; then HOST="dixie"; fi
virt-viewer -c qemu+ssh://ubuntu@${HOST}/system test
sleep 3
