dbbc9a3c40 qemu: Move and rename qemuDomainUpdateQEMUCaps
The function is now used only in qemu_process.c so move it there and
name it 'qemuProcessPrepareQEMUCaps' which is more appropriate to what
it's doing.

The reworded comment now mentions that it will also post-process the
caps for VM startup.

530d7a73f4 qemu: process: Don't try to redetect missing qemuCaps on reconnect
The redetection was originally added in 43c01d3838 as a way to recover
from libvirtd upgrade from the time when we didn't persist the qemu
capabilities in the status XML. Also this the oldest supported qemu by
more than two years.

Even if somebody would have a running VM running at least qemu 1.5 with
such an old libvirt we certainly wouldn't do the right thing by
redetecting the capabilities and then trying to communicate with qemu.

For now it will be the best to just stop considering this scenario any
more and error out for such VM.

2504dbeb5d qemu: process: Make it obvious that virDomainDefPostParse is called with NULL opaque
Commit c90fb5a828 added explicit use of the private copy of the qemu
capabilities to various places. The change to qemuProcessInit was bogus
though as at the point where we re-initiate the post parse callbacks
priv->qemuCaps is still NULL as we clear it after shutdown of the VM and
don't initiate it until a later point.

Using the value from priv->qemuCaps might mislead readers of the code
into thinking that something useful is being passed at that point so go
with an explicit NULL instead.

bbd54c10e7 API: Introduce VIR_DOMAIN_JOB_SUCCESS field for virDomainGetJobStats
The statistics fields are used in two places:

1) virDomainGetJobStats where the job type which ultimately holds
whether the job was successful or not is returned via a different
argument.

2) The virConnectDomainEventJobCompleted event where we report just the
statistics via typed parameters.

Since it might be useful to report the event also for jobs which
completed unsuccessfully and we don't have the means to transport the
state via a different variable with the event let's add a new field
which will hold the success state.

Since this is meant primarily for completed jobs a plain boolean is
sufficient to convey whether the job was successful or not.

8aaed287f5 qemu: make 'xz' image compression viable by using -3
For managed save we can choose between various compression
methods. I randomly tested the 'xz' program on a 8 GB guest
and was surprised to have to wait > 50 minutes for it to
finish compressing, with 'xz' burning 100% cpu for the
entire time. Despite the impressive compression, this is
completely useless in the real world as it is far too long
to wait to save the VM.

The 'xz' binary defaults to '-6' optimization level which
aims for high compression, with moderate memory usage,
at the expense of speed.

This change switches it to use the '-3' optimization level
which is documented as being the one that optimizes speed
at expense of compression. Even with this, it will still
outperform all the other options in terms of compression
level. It is a little less than x4 faster than '-6' which
means it starts to be a viable choice to use 'xz' for
people who really want best compression.

The test results on a 1 GB, fairly freshly booted VM are
as follows

  format | save  | restore  size
  =======+=======+=============
  raw    |   05s |    1s  | 428 MB
  lzop   |   05s |    3s  | 160 MB
  gzip   |   29s |    5s  | 118 MB
  bz2    |   54s |   22s  | 114 MB
  xz     | 4m37s |   13s  |  86 MB
  xz -3  | 1m20s |   12s  |  95 MB

Based on this we can say

 * For moderate compression with no noticable loss in speed

       => use lzop

 * For high compression with moderate loss in speed

       => use gzip

 * For best compression with significant loss in speed

       => use xz

6519c1b554 qemu: blockcopy: Fix conditions when virStorageSource should be initialized
Commit 4b58fdf280 which enabled block copy also for network
destinations needed to limit when the 'mirror' storage source is
initialized in cases when we e.g. don't have an appropriate backend.

Limiting it just to virStorageFileSupportsCreate is too restrictive as
for example we can't precreate block devices and thus wouldn't
initialize the 'mirror' but since it's a local source we'd try to
examine it. This would fail since it wouldn't be initialized.

Fix it by introducing a more granular check whether certain operations
are supported and fix the check interlocks.

5e9bdccd92 remote_daemon_stream: Hold an extra reference to stream in daemonStreamFilter
In v5.9.0-273-g8ecab214de I've tried to fix a lock ordering
problem, but introduced a crasher. Problem is that because the
client lock is unlocked (in order to honour lock ordering) the
stream we are currently checking in daemonStreamFilter() might be
freed and thus stream->priv might not even exist when the control
get to virMutexLock() call.

To resolve this, grab an extra reference to the stream and handle
its cleanup should the refcounter reach zero after the deref.
If that's the case and we are the only ones holding a reference
to the stream, we MUST return a positive value to make
virNetServerClientDispatchRead() break its loop where it iterates
over filters. The problem is, if we did not do so, then
"filter = filter->next" line will read from a memory that was
just freed (freeing a stream also unregisters its filter).

21986f5047 qemu: Fix indexes in statistics of iothreads
In commit 2ccb5335dc I've refactored how we fill the typed parameters
for domain statistics. The commit introduced a regression in the
formating of stats for IOthreads by using the array index to label the
entries as it's common for all other types of statistics rather than
the iothread IDs used for iothreads.

Since only the design of iothread deviates from the common approach used
in all other statistic types this was not caught.

d7dd4e1f89 nss: Don't fail on empty files
Before we rewrote nss plugin so that it doesn't use libvirt's
internal functions it used virLeaseReadCustomLeaseFile() to parse
.status files. After the rewrite it's using read() + yajl_parse()
+ yajl_complete_parse(). There's one catch though,
virLeaseReadCustomLeaseFile() skipped over empty files.

An empty .status file is created when a network is started. This
is because we configure dnsmasq to use our leasehelper. So the
first thing it does it calls it as follows:

  DNSMASQ_INTERFACE=virbr0 /usr/libexec/libvirt_leaseshelper init

which causes the leasehelper to create empty virbr0.status file.
If there is only one libvirt network then that is no problem -
there are no other .status files to parse anyway. But if there
are two or more networks then the first empty .status file causes
whole parsing process and subsequently the whole name lookup
process to fail.

Fixes: v5.7.0-rc1~343

a887da529c qemu: blockjob: Properly propagate cancellation of blockjobs
qemu returns an error message in the job statistics even if the job was
cancelled to emphasize it was not successful. Libvirt didn't properly
transform it into QEMU_BLOCKJOB_STATE_CANCELLED though.

27660f7990 util: whitelist Oracle ACFS as a shared filesystem
The magic number is taken from the coreutils stat.c file since
there is no constant for it in normal system headers.

a10eb61340 Revert "qemu: Don't repeat virDomainObjEndAPI in qemuDomainBlockPull"
This reverts commit 421c9550f5

qemuDomainBlockPullCommon calls virDomainObjEndAPI internally so the
original commit made us shed two references of @vm instead of one
getting us into a premature free of @vm.

This is not a straight revert as qemuDomainBlockPull was modified
meanwhile. I've also added a warning comment that @vm is consumed.

c8579871a9 all: don't wait for driver lock during startup
There are two daemons that wait for acquiring their pid files:
virtnetworkd and virtstoraged. This is undesirable as the idea
is to quit early if unable to acquire the pid file.

Fixes: v5.6.0-rc1~207.

3b9359cd44 check-symfile: Use pythonesque string formatting instead of perl
Commit d30a1ad044 translated the symbol file checker from perl to
python by doing a literal translation in most cases. Unfortunately one
string formatting operation was not really translated into python
leaving users with non-helpful error:

'Symbol $1 is listed twice'
