HVM vLAPIC timer interrupts intermittently disappearing
...see it when running on other hypervisors (VMware or KVM). We have seen this on guests with single or multiple vCPUs.
Is it possible that Xen has erroneously disabled the local APIC timer? Are there any useful diagnostics we could get out of Xen?
We''re running Xen 4.2.2, dom0 is Fedora Core18 (kernel 3.6.10-4.fc18.x86_64). Guest is RHEL6.4, kernel 2.6.32-358.0.1.el6.x86_64. Hardware is a Dell PowerEdge R620 server with 2 Intel Xeon E5-2690 6-core CPUs.
