d99e8f01c7 qemu: Prefer dashes for hyperv features
Starting with QEMU 4.1, we're using the canonical feature names on the
command line and avoid aliases to prepare for possible deprecation of
all aliases in QEMU. But we do so only for features from our CPU map,
hyperv features defined in the code were unchanged and this patch fixes
it. Some features use "hv-" prefix unconditionally because they were
introduced recently enough to always support spelling with a dash.

2c4c347c4b qemu: block: Use 'auto-read-only' instead of 'read-only' for backing chain
To allow using -blockdev with blockjobs QEMU needs to reopen files in
read-write mode when modifying the backing chain. To achieve this we
need to use 'auto-read-only' for the backing files rather than the
normal 'read-only' property. That way qemu knows that the files need to
be reopened.

Note that the format drivers (e.g. qcow2) are still opened with the
read-only property enabled when being a member of the backing chain
since they are supposed to be immutable unless a block job is started.

QEMU v4.0 (since commit 23dece19da4) allows also dynamic behaviour for
auto-read-only which allows us to use sVirt as we only grant write
permissions to files when doing a blockjob.

7711a7346a qemu: Relax os.loader->type check when validating domain
When validating a domain among all the checks there are two that
concern VIR_DOMAIN_LOADER_TYPE_PFLASH specifically. The first
check ensures that on x86 ACPI is enabled when UEFI is requested,
the second ensures that UEFI is used when ACPI is requested on
aarch64. However, check for UEFI is done by plain comparison of
def->os.loader->type which is insufficient because we have
def->os.firmware too.

NB, this wouldn't be a problem for active domain, because on
startup process def->os.loader->type gets filled by
qemuFirmwareEnableFeatures(), but that's not the case for
inactive domains.

regressions.

This feature is not meant for production use though, so users should

qemu: do not define known no-op features
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.

75a9169881 qemu: command: Override HOME variable for system QEMU
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.
This patch makes sure, that for system QEMU this is always set to
libDir/<driver>, session mode is left untouched.
