When starting a VirtualBox domain, we try to guess which frontend
to use. While the whole algorithm looks a bit outdated, it may
happen that we tell VirtualBox to use "gui" frontend, but not
which DISPLAY= to use.
I haven't found any documentation on the algorithm we use, but if
I make us fallback onto DISPLAY=:0 when no other configuration is
found then I'm able to start my guests just fine.

We have virDomainGetCPUStats() API which offers querying
statistics on host CPU usage by given guest. And it works in two
modes: getting overall stats (@start_cpu == -1, @ncpus == 1) or
getting per host CPU usage.
For the QEMU driver it is implemented by looking into values
stored in corresponding cpuacct CGroup controller. Well, this
works for system instances, where libvirt has permissions to
create CGroups and place QEMU process into them. But it does not
fly for session connection, where no CGroups are set up.
Fortunately, we can do something similar to v8.8.0-rc1~95 and use
virProcessGetStatInfo() to fill the overall stats. Unfortunately,
I haven't found any source of per host CPU usage, so we just
continue throwing an error in that case.

Firstly, the virProcessGetStatInfo() does not fail really. But
even if it did, it sets correct errno only sometimes (and even
that is done in a helper it's calling - virProcessGetStat() and
even there it's the case only in very few error paths).
Therefore, using virReportSystemError() to report errors is very
misleading. Use plain virReportError() instead. Luckily, there
are only two places where the former was used:
chDomainHelperGetVcpus() and qemuDomainHelperGetVcpus() (not a
big surprise since CH driver is heavily inspired by QEMU driver).

In a recent commit of v9.0.0-rc1~192 I've tried to forbid case
where a TAP device already exists, but at the same time it's
managed by Libvirt (<interface type='ethernet'> <target
dev='tap0' managed='yes'/> </interface>). NB, if @managed
attribute is missing then it's assumed to be managed by Libvirt.
Anyway, I've mistakenly put setting of
VIR_NETDEV_TAP_CREATE_ALLOW_EXISTING flag into managed='yes'
branch instead of managed='no' branch in
qemuInterfaceEthernetConnect().
Move the setting of the flag into the correct branch.

The VIR_NETDEV_TAP_CREATE_ALLOW_EXISTING flag is documented as:
/* The device is allowed to exist before creation */
VIR_NETDEV_TAP_CREATE_ALLOW_EXISTING = 1 << 4,
and yet, the documentation to virNetDevTapCreate() documents its
behavior when the flag is passed as:
* VIR_NETDEV_TAP_CREATE_ALLOW_EXISTING
* - The device creation fails if @ifname already exists
Fortunately, the function is implemented so that it follows the
expected behavior (i.e. the former flag documentation). Fix the
function documentation then.
