Such an attempt will lead to an abort() and a restart of any
vswitch using DPDK.

Hello,
When taking a snapshot of a running VM instance, using OpenStack
"nova image-create", I noticed that one OVS pmd-thread eventually
failed in DPDK rte_vhost_dequeue_burst() with repeating log entries:
compute-0-6 ovs-vswitchd[38172]: VHOST_DATA: Failed to allocate
memory for mbuf.

Hi,
during trouble shooting sessions (OVS 2.4.1, DPDK 2.2.0) it was noticed
that some guests trigger the SET_VRING_CALL message rather frequently. This
can be all from a few times per minute up to 10 times per second.
From DPDK log:
