This helper changes the root qdisc on given interface.
Ideally, it would be written using netlink but my attempts to
write the code were not successful and thus I've fallen back to
virCommand() + tc.

Currently setting max_len=0 causes virtlogd to spin in a busy loop. It
is natural to allow this to disable log rollover which can be useful for
developers debugging things.
Note disabling rollover exposes the host to denial of service from a
malicious guest, so must be used with care.

If storage migration is requested, and the destination storage does
not exist on the remote host, qemu's migration support will call
into the libvirt storage driver to precreate the destination storage.
The storage driver virConnectPtr is opened too early though, adding
an unnecessary dependency on the storage driver for several cases
that don't require it. This currently requires kubevirt to install
the storage driver even though they aren't actually using it.
Push the virGetConnectStorage calls to right before the cases they are
actually needed.

The aim of virSocketAddrPrefixToNetmask() is to initialize passed
virSocketAddr structure based on prefix length and family.
However, it doesn't set all members in the struct which may lead

Recently virtio-9p support was added to bhyve.
On the host side it looks this way:
bhyve .... -s 25:0,virtio-9p,sharename=/path/to/shared/dir
It could also have ",ro" suffix to make share read-only.
In the Linux guest, this share is mounted with:
mount -t 9p sharename /mnt/sharename
In the guest user will see the same permissions and ownership
information for this directory as on the host. No uid/gid remapping is
supported, so those could resolve to wrong user or group names.
The same applies to the other side: chowning/chmodding in the guest will
set specified ownership and permissions on the host.
In libvirt domain XML it's modeled using the 'filesystem' element:
<filesystem type='mount'>
<source dir='/path/to/shared/dir'/>
<target dir='sharename'/>
</filesystem>
Optional 'readonly' sub-element enables read-only mode.

With this commit, all architecture lists that we base feature
enablement decisions on are defined within a few lines of each
other, increasing maintainability.
Additionally, generic architecture lists that appear in the
conditions for multiple features are defined, so that repetition
is reduced.
Note that a few checks (numactl, zfs, ceph) have been changed
from %ifarch to %ifnarch for consistency: while doing so, the
corresponding list of architectures has also been replaced with
the complement of the original one to ensure the overall behavior
would be preserved.
