(Get the code!)
At a first glance this looks like all the hangs occur because the hypercall used to poll for the pv interrupts never returns. Has there been any change to then hypervisor on the affected instances? Or maybe some correlation with a specific type of hw running those?
Can we get the full dmesg of one of the hanging guests after a reboot (which I assume keeps it on the same host)? Did the instances just idle or where they used for some task that you can tell us about? Thanks.
