As an update, the issue occurred again on two different hosts for KVM machines.
Running pstack across the qemu process for the first KVM caused it to wake up, but the following was captured: http://pastebin.com/Js20eZPH On the second machine, running plockstat also woke the KVM up, but provided this: http://pastebin.com/pbEt2bnj On 29 Aug 2014, at 1:11 pm, David Finster via smartos-discuss <[email protected]<mailto:[email protected]>> wrote: I should also be more specific in saying that it appears that the VM locks up during this period of sleep. Once woken up, there are no event logs for the period that the machine was unreachable. Network activity isn’t the only thing affected.

The weird thing is that as soon as I jump into the hypervisor and run ‘vmadm info <uuid>’, the machine immediately starts responding to pings. I obtained the stacks of the qemu process, but accidentally ran vmadm info before I went further. Stacks can be found here: http://pastebin.com/8FBxrcJJ Does anyone have any suggestions/further debugging steps? Next time it happens I’ll see if I can obtain lock info and anything else I can think of. The KVM machines are running Server 2012 R2 64-bit (there are other machines also running this OS that aren’t having issues) and the issue is occurring on two separate hosts.
