Re: [libvirt] [PATCH] Wait for udev events to be handled after removing veth

As per http://www.redhat.com/archives/libvir-list/2013-July/msg01279.html, wait for udev events to be handled after removing a virtual NIC. Any udev rule associated to NIC destroy could happen to run with a new device with the same name that is being created. --- src/util/virnetdevveth.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/src/util/virnetdevveth.c b/src/util/virnetdevveth.c index 6905168..c8a38fb 100644 --- a/src/util/virnetdevveth.c +++ b/src/util/virnetdevveth.c @@ -225,5 +225,8 @@ int virNetDevVethDelete(const char *veth) ret = 0; cleanup: virCommandFree(cmd); + /* Make sure the device is properly down: creating a new one + * with the same name could lead to troubles */ + virFileWaitForDevices(); return ret; }
