We need to store the block job state in the status XML so that we can

happened while libvirt was not connected to the monitor.
First step is to note the name, type, state and corresponding disk into

lose the VM, thus many of the errors just mark the job as invalid.

Block jobs currently belong to disks only so we can look up the block

when using blockdev as certain jobs don't even correspond to a disk and

Add a global table of blockjobs which can be used to look up the data

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

When receiving multiple FDs from systemd during service activation it is
neccessary to identify which purpose each FD is used for. While this
could be inferred by looking for the specific IP ports or UNIX socket
paths, this requires the systemd config to always match what is expected
by the code. Using systemd FD names we can remove this restriction and
simply identify FDs based on an arbitrary name.
The FD names are passed by systemd in the LISTEN_FDNAMES env variable
which is populated with the socket unit file names, unless overriden
by using the FileDescriptorName setting.
This is supported since the system 227 release and unfortunately RHEL7
lacks this version. Thus the code has some back compat support whereby
we look at the TCP ports or the UNIX socket paths to identify what
socket maps to which name. This back compat code is written such that
is it easly deleted when we are able to mandate newer systemd.

The cleanup label in virNetworkObjDeletePort() function serves no
purpose. Drop it and thus simplify the function a bit.

The virNetworkObjGetPortStatusDir() function allocates a memory
to construct a path. None of the callers free it leading to a
memleak.

The virtlogd config is set to rollover logs every 2 MB.
Normally a logrotate config file is also installed to handle cases where
virtlogd is disabled. This is set to rollover weekly with no size
constraint.
As a result logrotate can interfere with virtlogd's, rolling over files
that virtlogd has already taken care of.
This changes logrotate configs to rollover based on a max size
constraint of 2 MB + 1 byte. When virtlogd is running the log files will
never get this large, making logrotate a no-op.
If the user changes the size in virtlogd's config to something larger,
they are responsible for also changing the logrotate config suitably.
The LXC/libxl drivers don't use virtlogd, but there logrotate config is
altered to match the QEMU driver config, for the sake of consistency.
