Since Hyper-V allows multiple VMs to be created with the same name,
some commands produce unpredictable results due to
hypervDomainLookupByName's WMI query selecting the wrong domain.
For example, this prevents `virsh dumpxml` from outputting XML for the
wrong domain.

The current formulation can lead people to believe SCSI

only difference is that you have to use model='virtio-scsi'

The _virDomainMemoryDef structure has @uuid member which is
needed for PPC64 guests. No other architectures use it. Since the
member is VIR_UUID_BUFLEN bytes long, the structure is
unnecessary big. If the member is just a pointer then we can also
replace some calls of virUUIDIsValid() with plain test against
NULL and also simplify formatter code which can now also check
the pointer against NULL.

Now we have everything prepared for generating the command line.
The device alias prefix was chosen to be 'virtiopmem'.
Since virtio-pmem-pci device goes onto PCI bus generating device
alias must have been changed slightly because
qemuAssignDeviceMemoryAlias() might have used DIMM slot number to
generate the alias. This obviously won't work and thus the "old"
way (which includes qemuDomainDeviceAliasIndex()) must be used.

The virtio-pmem is a virtio variant of NVDIMM and just like
NVDIMM virtio-pmem also allows accessing host pages bypassing
guest page cache. The difference is that if a regular file is
used to back guest's NVDIMM (model='nvdimm') the persistence of
guest writes might not be guaranteed while with virtio-pmem it
is.
To express this new model at domain XML level, I've chosen the
following:
<memory model='virtio-pmem' access='shared'>
<source>
<path>/tmp/virtio_pmem</path>
</source>
<target>
<size unit='KiB'>524288</size>
</target>
<address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/>
</memory>
Another difference between NVDIMM and virtio-pmem is that while
the former supports NUMA node locality the latter doesn't. And
also, the latter goes onto PCI bus and not into a DIMM module.

In the past, the MTU of libvirt virtual network bridge devices was
implicitly set by setting the MTU of the "dummy tap device" (which was
being added in order to force a particular MAC address from the
bridge). But the dummy tap device was removed in commit ee6c936fbb
(libvirt-6.8.0), and so the mtu setting in the network is ignored.
The solution is, of course, to explicitly set the bridge device MTU
when it is created.
Note that any guest interface with a larger MTU that is attached will
cause the bridge to (temporarily) assume the larger MTU, but it will
revert to the bridge's own MTU when that device is deleted (this is
not due to anything libvirt does; it's just how Linux host bridges
work).

managed='no' on an <interface> allows an unprivileged libvirt to use a
pre-created tap/macvtap device that libvirt has permission to
open/read/write, but no permission to modify (i.e. set the MTU or MAC
address). But when the XML had an <mtu size='blah'/> setting (which
was put there in order to tell the *guest* OS what MTU to set for the
emulated device at the other end of the tap) we were attempting to set
the MTU of the tap device on the host, paying no attention to the
setting of 'managed'. That would of course end in failure.
This patch only sets the MTU if managed='no' is *not* set (so, if it
is 'yes', or just not set at all).
Note that MTU of the tap is also set when connecting the tap to a
bridge device, but managed='no' is only allowed for <interface
type='ethernet'>, which would never attach to a bridge anyway, so we
don't need the check there.
