0ac13b189f virsh: Do not try connecting first time without polkit agent
Trying to connect once without a polkit agent will generate an error on the
server side which seems too rough given it only serves the purpose of the client
(virsh in this case) to figure out that an agent is needed.  Thankfully we can
just try running the agent.  It does not break anything as we are running it
with `--fallback`, which makes sure it does not replace an existing agent in
case there is one already registered.

The second piece of code trying to start the polkit text agent is kept in order
to _really_ try out starting the agent (and error out when failing to do so)
just in case the agent was not available the first time it was ran.  Even though
it should not happen it avoids a very rare race condition and really does not
add much complexity.

842cfc9d41 virsh: Remove unnecessary else branches
In a few cases we call a public API, wrapped in an if() statement
with both branches written out explicitly. The error branch jumps
onto cleanup label, while the successful prints out a message.
Right after these ifs there's 'ret = true;' and the cleanup
label. The code is a bit more readable if only the error branch
is kept and printing happens at the same level as setting the ret
variable.

6f31f3c9a0 virsh: Fix ambiguous output in metadata-change event
When you set metadata with type element like the following:
dom.setMetadata(libvirt.VIR_DOMAIN_METADATA_ELEMENT, "<test/>", 'abc', "HAHAH", 0)

Then for `virsh event --all`, then it will output this message:
event 'metadata-change' for domain 'rhel9': element HAHAH

The message is ambiguous since it looks like the params for
metadata-change event is the element HAHAH. Actually that means the type is
element while the url is HAHAH. Let's make it more clear.

289aa4bc5b virsh: Add QMP command wrapping for 'qemu-monitor-command'
Issuing simple QMP commands is pain as they need to be wrapped by the
JSON wrapper:

 { "execute": "COMMAND" }

and optionally also:

 { "execute": "COMMAND", "arguments":...}

For simple commands without arguments we can add syntax sugar to virsh
which allows simple usage of QMP and additionally prepares also for
passing through of the 'arguments' section:

 virsh qemu-monitor-command $VM query-status

is equivalent to

 virsh qemu-monitor-command $VM '{"execute":"query-status"}'

and

 virsh qemu-monitor-command $VM query-named-block-nodes '{"flat":true}'
 or
 virsh qemu-monitor-command $VM query-named-block-nodes '"flat":true'

is equivalent to

 virsh qemu-monitor-command $VM '{"execute":"query-named-block-nodes", "arguments":{"flat":true}}'

9985f62b51 qemu: Wire up MEMORY_DEVICE_SIZE_CHANGE event
As advertised in previous commit, this event is delivered to us
when virtio-mem module changes the allocation inside the guest.
It comes with one attribute - size - which holds the new size of
the virtio-mem (well, allocated size), in bytes.
Mind you, this is not necessarily the same number as 'requested
size'. It almost certainly will be when sizing the memory up, but
it might not be when sizing the memory down - the guest kernel
might be unable to free some blocks.

This current size is reported in the domain XML as an output
element only.

bc4739ed77 virsh: Expand VIRSH_COMMON_OPT_FILE for cases when it's not a local file used by virsh
In cases such as the APIs for managed save management, the file path
provided via the '--file' option is passed to the API.

We'll need to make them distinct from cases for when virsh is using the
file so that different completers can be used.

This was broken by a mistake in a recent refactor where a 'goto cleanup'

and also caused a memory leak.

Return the fallback cpu map.

dc721f99df virsh: fix setmem flags logic
When we dropped virDomainSetMemory usage it got kind of tricky to
figure out the flags correctly.

Originally the logic was following:

    no option | --current | --live | --config | --live --config
    ----------+-----------+--------+----------+----------------
       LIVE   |  CURRENT  |  LIVE  |  CONFIG  |  LIVE & CONFIG

But after the commit removing virDomainSetMemory usage it changed to:

    no option | --current | --live |    --config     | --live --config
    ----------+-----------+--------+-----------------+----------------
       LIVE   |  CURRENT  |  LIVE  |  LIVE & CONFIG  |  LIVE & CONFIG

This commit fixes the logic back to the original behavior except for
ESX, HyperV and Virtuozzo drivers where virDomainSetMemory() default
behavior was CURRENT instead of LIVE.

f798970b18 tools: only fail validations if VIR_HOST_VALIDATE_FAIL is set
Currently `virt-host-validate` will fail whenever one of its calls fail,
regardless of virHostValidateLevel set.

This behaviour is not optimal and makes it not exactly reliable as a
command line tool as other tools or scripts using it would have to check
its output to figure out whether something really failed or if a warning
was mistakenly treated as failure.

With this change, the behaviour of whether to fail or not, is defined by
the caller of those functions, based on the virHostValidateLevel passed
to them.

56fbabf1a1 Add basic driver for the Cloud-Hypervisor
Cloud-Hypervisor is a KVM virtualization using hypervisor. It
functions similarly to qemu and the libvirt Cloud-Hypervisor driver
uses a very similar structure to the libvirt driver.

The biggest difference from the libvirt perspective is that the
"monitor" socket is seperated into two sockets one that commands are
issued to and one that events are notified from. The current
implementation only uses the command socket (running over a REST API
with json encoded data) with future changes to add support for the
event socket (to better handle shutdowns from inside the VM).

This patch adds support for the following initial VM actions using the
Cloud-Hypervsior API:
 * vm.create
 * vm.delete
 * vm.boot
 * vm.shutdown
 * vm.reboot
 * vm.pause
 * vm.resume

To use the Cloud-Hypervisor driver, the v15.0 release of
Cloud-Hypervisor is required to be installed.

Some additional notes:
 * The curl handle is persistent but not useful to detect ch process
 shutdown/crash (a future patch will address this shortcoming)
 * On a 64-bit host Cloud-Hypervisor needs to support PVH and so can
 emulate 32-bit mode but it isn't fully tested (a 64-bit kernel and
 32-bit userspace is fine, a 32-bit kernel isn't validated)

ce8138564b virsh-domain: Drop support for old APIs in cmdSetmem and cmdSetmaxmem
Some of our really old APIs are missing @flags argument. We
introduced their variants with "Flags" suffix and wired some
logic into virsh to call the new variant only if necessary. This
enables virsh to talk to older daemon which may be lacking new
APIs.

However, in case of cmdSetmem() we are talking about v0.1.1
(virDomainSetMemory()) vs. v0.9.0 (virDomainSetMemoryFlags()) and
in case of cmdSetmaxmem() we are talking about v0.0.3
(virDomainSetMaxMemory()) vs v0.9.0 (virDomainSetMemoryFlags()).

Libvirt v0.9.0 was released more than 10 years ago and recently
we dropped support for RHEL-7 which has v4.5.0 (released ~3 years
ago). Thus it is not really necessary to have support in virsh
for such old daemons.

cf66ee8ddc tools: Generate per-command bash completion script
The current setup uses a single script that is symlinked twice
and that tries to configure bash completion for both virsh and
virt-admin, even if only one of them is installed. This also
forces us to have a -bash-completion RPM package that only
contains the tiny shared file.

Rework bash completion support so that two scripts are
generated, each one tailored to a specific command.

Since the shared script no longer exists after this change,
the corresponding RPM package becomes empty.

7657804df7 bash-completion: Fix argument passing to $1
Our vsh bash completion string is merely just a wrapper over
virsh/virt-admin complete (cmdComplete) - a hidden command that
uses internal readline completion to generate list of candidates.
But this means that we have to pass some additional arguments to
the helper process: e.g. connection URI and R/O flag.

Candidates are printed on a separate line each (and can contain
space), which means that when bash is reading the helper's output
into an array, it needs to split items on '\n' char - hence the
IFS=$'\n' prefix on the line executing the helper. This was
introduced in b889594a70.

But this introduced a regression - those extra arguments we might
pass are stored in a string and previously were split on a space
character (because $IFS was kept untouched and by default
contains space). But now, after the fix that's no longer the case
and thus virsh/virt-admin sees ' -r -c URI' as one argument.

The solution is to take $IFS out of the picture by storing the
extra arguments in an array instead of string.

allocated elements for the API but 'count' can be '-1' in cases when the
API returns failure, thus attempting to free beyond the end of the
array.

f1c9fed2ca virsh: snapshot: Don't validate schema of XML generated by 'virsh snapshot-create-as'
Commit 95f8e3237e which introduced XML schema validation
for snapshot XMLs always asserted the validation for the XML generated
by 'virsh snapshot-create-as' on the basis that it's libvirt-generated,
thus valid.

This unfortunately isn't true as users can influence certain bits of the
XML such as the disk image path which must be a full path. Thus if a
user tries to invoke virsh as:

 $ virsh snapshot-create-as upstream --diskspec vda,file=relative.qcow2
 error: XML document failed to validate against schema: Unable to validate doc against /path/to/domainsnapshot.rng
 Extra element disks in interleave
 Element domainsnapshot failed to validate content

They get a rather useless error from the libxml2 RNG validator.

With this fix applied, we get to the XML parser in libvirtd which has a
more reasonable error:

 $ virsh snapshot-create-as upstream --diskspec vda,file=relative.qcow2
 error: XML error: disk snapshot image path 'relative.qcow2' must be absolute

Instead users can force validation of the XML generated by 'virsh
snapshot-create-as' by passing the '--validate' flag.

c8238579fb lib: Drop internal virXXXPtr typedefs
Historically, we declared pointer type to our types:

  typedef struct _virXXX virXXX;
  typedef virXXX *virXXXPtr;

But usefulness of such declaration is questionable, at best.
Unfortunately, we can't drop every such declaration - we have to
carry some over, because they are part of public API (e.g.
virDomainPtr). But for internal types - we can do drop them and
use what every other C project uses 'virXXX *'.

This change was generated by a very ugly shell script that
generated sed script which was then called over each file in the
repository. For the shell script refer to the cover letter:

The libvirt_recover_xattrs.sh script can be used to remove stale
XATTRs that were left behind by secdrivers (which should happen
only if there's an imbalance between set and restore calls).
Anyway, the script has '-n' switch which is supposed to perform
just a dry run, i.e. just to report which files have XATTRs set
without any attempt to remove them.

But, when rewriting the script a few months ago a typo was
introduced which made the script report no files even if there
were files with XATTRs.
