Specify the memory size by using '-m size=2048k' instead of just '-m 2'.
The new syntax is used when memory hotplug is enabled. To preserve
memory sizing, if memory hotplug is disabled the size is rounded down to
the nearest mebibyte.

We currently use -machine accel=XXX which is just a syntax sugar
for -accel XXX. The former doesn't allow specifying arguments for
accelerator, because all arguments passed to -machine are
treated as arguments of machine itself.
The -accel argument was introduced in QEMU commit
v2.9.0-rc0~70^2~19 and since our minimum required version is
newer (2.11.0) we can safely assume its existence and use it
without any capability.

CPUs who do not provide their own implementation of feature parsing
will treat each option as a QOM property and set it to the supplied

Libvirt names use underscores so we conditionally tranlate the

virCommandToString has the possibility to return an already wrapped
string with better format than what we get from the test wrapper script.
The main advantage is that arguments for an option are always on the
same line which makes it more easy to see what changed in a diff and
prevents re-wrapping of the line if a wrapping point moves over the
threshold.
Additionally the used output is the same we have in the VM log file when
a VM is starting.

Qemu dropped cpu features for osxsave and ospke [1][2].
The reason for the instant removal is that those features were never
configurable as discussed in [3].
Fortunately the use cases adding those flags in the past are rare, but
they exist. One that I identified are e.g. older virt-install when used
with --cpu=host-model and there always could be the case of a user
adding it to the guest xml.
This triggers an issue like:
qemu-system-x86_64: can't apply global Broadwell-noTSX-x86_64-
cpu.osxsave=on: Property '.osxsave' not found
Ensure that this does no more break spawning newer qemu versions by
not rendering those features into the qemu command line.

By default, qemu user's home dir points to '/' which shouldn't be used
at all. We therefore pass the HOME variable from the current variable
iff not running as SUID, which means that for systemd we never set it.
