Re: [PATCH] qemu: support vlan change for linux host bridge during update-device

Since we previously only supported vlan tagging for interfaces connected to an OVS bridge [*], the code in qemuChangeNet() (used by the update-device API) assumed an interface with modified vlan config was on an OVS bridge, and would call the OVS-specific virNetDevOpenvswitchUpdateVlan(). Now that we support vlan tagging for interfaces connected to a standard Linux host bridge, we must check the type of connection and only call the OVS function when connected to an OVS bridge *both before and after the update*. Otherwise we just set the flag to re-connect to the bridge, which has the side effect of redoing the vlan setup. ([*] or an SRIOV VF assigned using VFIO, but we don't support *any runtime changes to that type of netdev so it's irrelevant here.) Signed-off-by: Laine Stump <laine(a)redhat.com&gt; --- I'm fine with this going in either before or after the 11.0.0 release (would prefer before since it is a bugfix), but if it's going into the release I'd rather it be included with RC2 rather than only in the final release. For that reason, if someone ACKs the patch and agrees that it's safe to go in, please push it for me (since Jiri will almost certainly tag RC2 before I'm conscious on Monday morning) src/qemu/qemu_hotplug.c | 32 ++++++++++++++++++++++++-------- 1 file changed, 24 insertions(+), 8 deletions(-)
