runqemu: Ensure we process all tap devices
The regexp in the script misses some tap devices, e.g. we see output like: runqemu - INFO - Acquiring lockfile /tmp/qemu-tap-locks/tap25.lock failed: [Errno 11] Resource temporarily unavailable runqemu - INFO - Acquiring lockfile /tmp/qemu-tap-locks/tap26.lock failed: [Errno 11] Resource temporarily unavailable runqemu - INFO - Acquiring lockfile /tmp/qemu-tap-locks/tap27.lock failed: [Errno 11] Resource temporarily unavailable runqemu - INFO - Acquiring lockfile /tmp/qemu-tap-locks/tap28.lock failed: [Errno 11] Resource temporarily unavailable runqemu - INFO - Acquiring lockfile /tmp/qemu-tap-locks/tap40.lock failed: [Errno 11] Resource temporarily unavailable runqemu - INFO - Acquiring lockfile /tmp/qemu-tap-locks/tap41.lock failed: [Errno 11] Resource temporarily unavailable What happened to tap29 to tap39? The issue is was we were missing devices with '0' in the number, like "10:" and so on in the output from "ip link". Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
