When QEMU is used with Open vSwitch it is common to create netdev
script and downscript scripts that use the ovs-vsctl command to manage
the underlying network devices. Unfortunately, ovs-vsctl calls the
getrusage() syscall which is not currently present in the QEMU/seccomp
whistelist.

NACK, when QEMU is used in sandbox mode you should use file descriptor
passing instead.
