546010ff94 domcapabilities: Add supports_filesystem_virtiofs()
Check whether virtiofs is exposed in domcapabilities, We can use it as a
proxy for 'libvirt is new enough to allow bare memory access mode=shared'
as well.

f13c8d87fb guest: Remove the hyperv + uefi workaround for win7 + win2k8r2

eb58c09f48 virtinst/guest: enable a TPM by default if UEFI is present
The bare metal world is moving to a situation where UEFI is going to be
the only supported firmware and there will be a strong expectation for
TPM and SecureBoot support.

With this in mind, if we're enabling UEFI on a VM, it makes sense to
also provide a TPM alongside it.

Since this requires swtpm to be installed we can't do this
unconditionally. The forthcoming libvirt release expands the domain
capabilities to report whether TPMs are supported, so we check that.

The user can disable the default TPM by requesting --tpm none

5622854d8c virtinst: refactor setting of default vcpus count
The sync_vcpus_topology method will sometimes set the self.vcpus prop,
but other times leave it unset. This is confusing an unhelpful
behaviour. Both callers have logic to set the self.vcpus prop
to a default value of sync_vcpus_topology failed to do so. It makes
more sense to just pass this default value in.

883419c214 virtinst: allow to force create topology from scratch
When setting CPU defaults we want to force create the topology even if
the user has not specified anything. In particular this allows for
overriding the QEMU defaults, to expose vCPUs as cores instead of
sockets which is a much saner default for Windows.

9a578e1ac5 virtinst: prefer cores when exposing topology to the guest
In real world silicon though it is rare to have high socket/die counts,
but common to have huge core counts.

Some OS will even refuse to use sockets over a certain count.

Thus we prefer to expose cores to the guest rather than sockets as the
default for missing fields.

This matches a recent change made in QEMU for new machine types

e1c8866163 virtinst: validate that the CPU topology is sane
The product of sockets * dies * cores * threads must be equal to the
vCPU count. While libvirt and QEMU will report this error scenario,
it makes sense to catch it in virt-install, so we can test our local
logic for setting defaults for topology.

This exposes some inconsistent configurations in the test suite.

609007c9ca virtinst: make CPU topology defaulting take account of dies
Any missing values in the topology need to be calculated based on the
other values which are set.

We can take account of fact that 'total_vcpus' treats any unset values
as being 1 to simplify the way we set topology defaults.

This ensures that topology defaulting takes account of dies.

9e133de21a diskbackend: Restrict format->driver_type even more
We should only be returning a driver_type value for volumes that
report support_format(), meaning they support file type formats like
qcow2. Any other reported format should be ignored

okay

2676640979 Disk pool volumes should be always attached as "raw" disks
Usually, when storage volume is attached as a disk and disk xml is filled with
default values, the "<driver type=...>" value is copied from volume's
"<format type=...>".  This makes sense for volumes of storage pool of type
"dir", where format types include "raw, qcow2...".

However, the same approach cannot be used for the storage pool of type "disk".
In that case, format types include "none, linux, fat16, fat32...". Such formats
cannot be used for disk's "<driver type=...>".

Therefore, when generating disk XML for volume of storage pool type "disk",
driver type should always be "raw".

9766beea04 cli: add 'ioapic.driver' to --features
Add the ability to set the ioapic driver using the --features argument:

    $ virt-install --features ioapic.driver=qemu ...

This results in the following xml:

  <features>

    <ioapic driver="qemu"/>
  </features>

This is required in order to install a guest with >255 cpus. Such a
configuration requires an iommu with extended interrupt mode enabled,
which in turn requires IOMMU interrupt remapping to be enabled, which in
turn requires a split I/O APIC.

2e2d3b84bc installerinject: Use root:root instead of +0:+0 as owner
Commit c6b5f22fa6 started passing the --owner argument to
cpio when injecting files into the initrd to comply with the
more strict requirements introduced by systemd starting with
Fedora 30.

However, cpio only started accepting the +uid:+gid syntax in
version 2.12, which means that the fix actually broke the
initrd inject functionality completely in RHEL 7 and other
distros that don't include a recent enough cpio.

Use the user:group syntax instead, which is understood by
all versions of cpio, including non-GNU ones.

0c146b2503 Handle new nodedev name for mediated devices
libvirt recently changed the nodedev names for mediated devices due to
the fact that mdevctl supports defining multiple mediated devices with
the same UUID as long as only one is active at a time. This means that
the nodedev name changed from the format 'mdev_$UUID' to the format
'mdev_$UUID_$PARENT'.

Unfortunately, virt-install was parsing the nodedev name to extract the
UUID of a mediated device. This fails with the new name format.
Fortunately, in libvirt 7.3.0, a <uuid> field was added to the xml
schema for mdev devices, so we can simply use this instead, and fall
back to the name parsing if it doesn't exist.
