      qemu: Use the correct vm def on cold attach · 55ce6564
      由 John Ferlan 提交于 
      https://bugzilla.redhat.com/show_bug.cgi?id=1559867

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.

      network: Use 'switch' control statement with virNetworkForwardType enum · 7564daca

      With 'switch' we can utilize the compile time enum checks which we can't
rely on with plain 'if' conditions.

      qemuDomainSaveMemory: Don't enforce dynamicOwnership · 8c8c3233
      由 Michal Privoznik 提交于 
      https://bugzilla.redhat.com/show_bug.cgi?id=1589115

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.

      src: Make virStr*cpy*() functions return an int · 6c0d0210
      由 Andrea Bolognani 提交于 
      Currently, the functions return a pointer to the
destination buffer on success or NULL on failure.

Not only does this kind of error handling look quite
alien in the context of libvirt, where most functions
return zero on success and a negative int on failure,
but it's also somewhat pointless because unless there's
been a failure the returned pointer will be the same
one passed in by the user, thus offering no additional
value.

Change the functions so that they return an int
instead.
