When connecting to the monitor, a timeout is calculated that is
bigger the more memory guest has (because QEMU has to allocate
and possibly zero out the memory and what not, empirically
deducted). However, when computing the timeout the @total_memory
mmember is accessed directly even though
virDomainDefGetMemoryTotal() should have been used.

There were a number of occurrences where we used nested inline markup
(verbatim + refs) which is currently not possible with RST syntax [1].
There is a possible workaround involving substitution definitions like
.. |virConnectPtr| replace:: ``virConnectPtr``
.. _virConnectPtr: /html/libvirt-libvirt-host.html#virConnectPtr
Substitutions cannot be made generic, hence we cannot create a template
for substitution and use a single template everywhere, so we'd end up
with a lot of clutter and convolution. Therefore, we can make an
exception and just link the data type without further style markup.

The aim of virSecurity rule is to discourage from using plain
virSecurityManager*() APIs within QEMU driver in favor of their
qemuSecurity*() counterparts. The reason is simple: namespaces;
virSecurityManager*() needs additional
virSecurityManagerTransactionCommit() call to enter given
namespace and do its work from there. And that's exactly what
those qemuSecurity*() wrappers do.
To help us ensure correctness (from this POV), we have a
syntax-check rule that forbids any occurrence of
"virSecurityManager" string under src/qemu/ (except for
qemu_security of course).
But with if we want to remove virSecurityManagerPtr type, then we
have to allow "virSecurityManager *". Therefore, change the rule
so that no call of a function with "virSecurityManager" prefix is
allowed. And also change the name to better reflect what is going
on.

The qemu shim spawns a separate thread in which the event loop is
ran. The virEventRunDefaultImpl() call is wrapped in a while()
loop, just like it should. There are few lines of code around
which try to ensure that domain is destroyed (when quitting) and
that the last round of event loop is ran after the
virDomainDestroy() call. Only after that the loop is quit from
and the thread quits.
However, if domain creation fails, there is no @dom to call
destroy over, the @quit flag is never set and while() never
exits. Set the flag regardless of @dom pointer.

This problem is reproducible only with secret driver. When
starting a domain via virt-qemu-run and both secret and
(nonexistent) root directory specified this is what happens:
1) virt-qemu-run opens "secret:///embed?root=$rootdir"
connection, which results in the secret driver initialization
(done in secretStateInitialize()). During this process, the
driver creates its own configDir (derived from $rootdir)
including those parents which don't exists yet. This is all
done with the mode S_IRWXU and thus results in the $rootdir
being created with very restrictive mode (specifically, +x is
missing for group and others).
2) now, virt-qemu-run opens "qemu:///embed?root=$rootdir" and
calls virDomainCreateXML(). This results in the master-key.aes
being written somewhere under the $rootdir and telling qemu
where to find it.
But because the secret driver created $rootdir with too
restrictive mode, qemu can't access the file (even though it
knows the full path) and fails to start.
It looks like the best solution is to pre-create the root
directory before opening any connection (letting any driver
initialize itself) and set its mode to something less
restrictive.
