Introduced a line:
if ((def->virtType = virDomainVirtTypeFromString(virttype)) < 0) {
which causes a build failure with CLang
conf/domain_conf.c:19143:65: error: comparison of unsigned enum expression < 0 is always false [-Werror,-Wtautological-compare]

assumption that the enum type is unsigned and always in range.

Commit id fca9afa08 changed the @req->ifname to use
@req->binding->portdevname fillingin the @req->binding
in a similar way that @req->ifname would have been
filled in during virNWFilterDHCPSnoopReq processing.
However, in doing so it did not take into account some
code paths where the @req->binding should be checked
instead of @req->binding->portdevname. These checks
led to SEGVs in some cases during libvirtd reload
processing in virNWFilterSnoopRemAllReqIter (for
stop during nwfilterStateCleanup processing) and
virNWFilterSnoopReqLeaseDel (for start during
nwfilterStateInitialize processing).
In particular, when reading the nwfilter.leases file
a new @req is created, but the @req->binding is not
filled in. That's left to virNWFilterDHCPSnoopReq
processing which checks if the @req already exists
in the @virNWFilterSnoopState.snoopReqs hash table
after adding a virNWFilterSnoopState.ifnameToKey
entry for the @req->binding->portdevname by a
@ref->ikey value.
NB: virNWFilterSnoopIPLeaseInstallRule and
virNWFilterDHCPSnoopThread do not need the
req->binding check since they can only be called
after the filter->binding is created/assigned.

Consider creating a listener socket from a hostname that resolves to
multiple addresses. It might be the case that the hostname resolves to
both an IPv4 and IPv6 address because it is reachable over both
protocols, but the IPv6 connectivity is provided off-host. In such a
case no local NIC will have IPv6 and so bind() would fail with the
EADDRNOTAVAIL errno. Thus it should be treated as non-fatal as long as
at least one socket was succesfully bound.

When attaching a device to the domain we need to be sure
to use the correct domain definition (vm->def or vm->newDef)
when calling virDomainDeviceDefParse because the post parse
processing algorithms that may assign an address for the
device will use whatever domain definition was passed in.
Additionally, some devices (SCSI hostdev and SCSI disk) use
algorithms that rely on knowing what already exists of the
other type when generating the new device's address. Using
the wrong VM definition could result in duplicated addresses.
In the case of the bz, two hostdev's with no domain address
provided were added to the running domain's config only.
However, the parsing algorithm used the live domain in
order to figure out the host device address resulting in
the same address being used and a subsequent start failing
due to duplicate address.
Fix this by separating the checks/code into CONFIG and LIVE
processing using the correct definition for each block and
performing cleanup for both options as necessary.

When doing a memory snapshot qemuOpenFile() is used. This means
that the file where memory is saved is firstly attempted to be
created under root:root (because that's what libvirtd is running
under) and if this fails the second attempt is done under
domain's uid:gid. This does not make much sense - qemu is given
opened FD so it does not need to access the file. Moreover, if
dynamicOwnership is set in qemu.conf and the file lives on a
squashed NFS this is deadly combination and very likely to fail.
The fix consists of using:
qemuOpenFileAs(fallback_uid = cfg->user,
fallback_gid = cfg->group,
dynamicOwnership = false)
In other words, dynamicOwnership is turned off for memory
snapshot (chown() will still be attempted if the file does not
live on NFS) and instead of using domain DAC label, configured
user:group is set as fallback.
