Hello Marcelo,
well, my report might have been a bit misleading, 2.6.31.2 has been running
there for almost 3 weeks.
So the problem didn't occur JUST after the upgrade. But it never occured before
it, while

What it is: vhost net is a character device that can be used to reduce
the number of system calls involved in virtio networking.
Existing virtio net code is used in the guest without modification.

This patch extends the qemu-kvm state sync logic with the event substate
from the new VCPU state interface, giving access to yet missing
exception, interrupt and NMI states.
The patch does not switch the rest of qemu-kvm's code to the new
interface as it is expected to be morphed into upstream's
Drop interrupt_bitmap from the cpustate and solely rely on the integer
interupt_injected. This prepares us for the new injected-interrupt
interface, which will deprecate the bitmap, while preserving
compatibility.
