These patches are in response to a bug report filed a few years ago
where I said "I can look at it next week" and then promptly forgot
about it :-/
https://bugzilla.redhat.com/1949432
I was reminded of it when a bunch of old bugs were migrated from
bugzilla.redhat.com to
issues.redhat.com and Yalan Zhang added the
comment that the bug was still reproducible on libvirt 10.4.0.
https://issues.redhat.com/browse/RHEL-7036
This got it back onto my todo list (where it should have been the
entire time!) and I've finally gotten to it. Two similar-but-differen
failures had been reported (one when using a network of "direct"
(macvtap) devices, and one when using an openvswitch bridge, and it
turned out that two different (but related) fixes were needed - the
direct problem is fixed *mostly* in patch 1, with the other patches
fixing the ovs problem (and the remainder of the direct problem).
Laine Stump (4):
qemu: prevent unnecessarily failing live interface update
util: don't return early from virNetDevTapReattachBridge() if "force"
is true
qemu: replace open-coded remove/attach bridge with
virNetDevTapReattachBridge()
qemu: rework needBridgeChange/needReconnect decisions in
qemuDomainChangeNet()
