We are not guaranteed that the string we are printing onto stdout
contains '\n' and thus that the stdout is flushed. In fact, I've
met this problem when virsh asked me whether I want to edit the
domain XML again (vshAskReedit()) but the prompt wasn't displayed
(as it does not contain a newline character) and virsh just sat
there waiting for my input, I sat there waiting for virsh's
output. Flush stdout after all fputs()-s which do not flush

Historically the use of the '-desc' multiple argument parameter was not
forbidden toghether with '-edit', but use of both together has some
unexpected behaviour. Specifically the editor is filled with the
contents passed via '-desc' but if the user doesn't change the text in
any way virsh will claim that the description was not chaged even if it
differs from the currently set description. Similarly, when the user
would edit the description provided via 'desc' so that it's identical
with the one configured for the domain, virsh would claim that it was
updated:
# virsh desc cd
No description for domain: cd
# EDITOR=true virsh desc cd --edit "test desc"
Domain description not changed
After the fix:
# virsh desc cd
No description for domain: cd
# EDITOR=true virsh desc cd --edit "test desc"
Domain description updated successfully
# EDITOR=true virsh desc cd --edit "test desc"
Domain description not changed

Since libvirt-guests script/service can operate on various URIs and we do
support both socket activation and traditional services, the ordering should be
specified for all the possible sockets and services.
Also remove the Wants= dependency since do not want to start any service. We
cannot know which one libvirt-guests is configured, so we'd have to start all
the daemons which would break if unused colliding services are not
masked (libvirtd.service in the modular case and all the modular daemon service
units in the monolithic scenario). Fortunately we can assume that the system is
configured properly to start services/sockets that are of interest to the user.
That also works with the setup described in https://libvirt.org/daemons.html .
To make it even more robust we add the daemon service into the machine units
created for individual domains as it was missing there.

bytes as a hex numbers using our own implementation. But
wireshark already provides a function for it: tvb_bytes_to_str().
NB, the reason why it returns a const string is so that callers
don't try to free it - the string is allocated using an allocator
which will decide when to free it.

Trying to connect once without a polkit agent will generate an error on the

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

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)

However, in case of cmdSetmem() we are talking about v0.1.1

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

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.

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

The way we currently call completer callbacks is that if we've
found --option that user wants to complete value for and it has
callback set then the callback is called.
And just before that, if no --option to have the value completed
is found or is found and is of boolean type then a list of
--option is generated (for given command).
But these two conditions can never be true at the same time
because boolean type of --options do not accept values. Therefore
the calling of completer callback can be promoted onto the same
level as the --option list generation.
This means that merging of two lists can be dropped to and
completer callback can store its retval directly into @list (but
as shown earlier one of the string lists to merge is always
empty).

The vshReadlineParse() function is called whenever user hits
<TAB><TAB>. If there is no command (or a partially written one),
then a list of possible commands is printed to the user. But, if
there is a command then its --options are generated. But
obviously, we can not generate --options if there already is an
--option that's expecting a value. For instance, consider:
virsh # start --domain <TAB><TAB>
In this case we want to call completer for --domain option, but
that's a different story.
Anyway, the way that we currently check whether --options list
should be generated is checking the type of the last --option. If
it isn't DATA, STRING, INT, or ARGV (all these expect a value),
then we can generate --option list. Well, writing the condition
this way is needlessly verbose and also prone to errors (see
d9a320bf97 for example).
We know that boolean type does not require a value. This leaves
us with the only type that was not mentioned yet - VSH_OT_ALIAS.
This is a special type for backwards compatibility and it refers
to another --option which can be just any type.

The aim of vshCompleterFilter() is to take a string list and a
prefix and remove all strings from the list that don't have the
desired prefix. The function is used to filter out those strings
returned by a completer callback that don't correspond with
user's (partial) input. For instance, domain name completer
virshDomainNameCompleter() returns all domain names and then
vshCompleterFilter() refines the list so that only domains with
correct prefix of their name are offered to user. This was a
design choice - it allows us to have shorter completers as they
do not have to copy the list filtering over and over.
Having said all of that, it may happen that a completer does not
return anything (e.g. there is no domain in requested state,
virsh is not connected and thus completer exited early, etc.). In
that case, the string list is NULL and vshCompleterFilter() can
simply return early.

The way our bash completion string is that is gets user's input
and lets virsh completion code do all the work by calling 'virsh
complete -- $INPUT". The 'complete' command is a "secret",
unlisted command that exists solely for this purpose. After it
has done it's part, it prints candidates onto stdout, each
candidate on its own line, e.g. like this:
# virsh complete -- "net-u"
net-undefine
net-update
net-uuid
These strings are then stored into a bash array $A like this:
A=($($1 ${CMDLINE} complete -- "${INPUT[@]}" 2>/dev/null))
This array is then thrown back at bash completion to produce
desired output. So far so good. Except, when there is an option
with space. For instance:
# virsh complete -- start --domain ""
uefi\ duplicate
uefi
Bash interprets that as another array item because by default,
Internal Field Separator (IFS) = set of characters that bash uses
to split words at, is: space, TAB, newline. We don't want space
nor TAB. Therefore, we have to set $IFS when storing 'virsh
complete' output into the array.

If user is trying to auto complete a value that contains a space,
they have two options: use backslash to escape space or use
quotes, like this:
virsh # start --domain "domain with space<TAB>
However, in this case our tokenizer sees imbalance in (double)
quotes: there is a starting one that's missing its companion.
Well, that's obvious - user is still in process of writing the
command. What we need to do in this case is to ignore the
imbalance and return success (from the tokenizer) - readline will
handle closing the quote properly.

The way that auto completion works currently is that user's input
is parsed, and then we try to find the first --option (in the
parsed structure) that has the same value as user's input around
where <TAB> was pressed. For instance, for the following input:
virsh # command --arg1 hello --arg2 world<TAB>
we will see "world" as text that user is trying to autocomplete
(this is affected by rl_basic_word_break_characters which
readline uses internally to break user's input into individual
words) and find that it is --arg2 that user is trying to
autocomplete. So far so good, for this naive approach. But
consider the following example:
virsh # command --arg1 world --arg2 world<TAB>
Here, both arguments have the same value and because we see
"world" as text that user is trying to autocomplete we would
think that it is --arg1 that user wants to autocomplete. This is
obviously wrong.
Fortunately, readline stores the current position of cursor (into
rl_point) and we can use that when parsing user's input: whenever
we reach a position that matches the cursor then we know that
that is the place where <TAB> was pressed and hence that is the
--option that user wants to autocomplete. Readline stores the
cursor position as offset (numbered from 1) from the beginning of
user's input. We store this input into @parser->pos initially,
but then advance it as we tokenize it. Therefore, what we need is
to store the original position too.
Thanks to Martin who helped me with this.

The way our completer callbacks work is that they return all
possible candidates and then vshCompleterFilter() is called to
prune the list of all candidates removing those which don't match
user's input. This allows us to have simpler completer callbacks
as their only job is to fetch all possible candidates.
Anyway, if the completion candidate we're returning contains a
space, it has to be escaped (shell like escaping), unless there
is already a quote character (single quote or double quote).
But ordering is critical. Completer callback returns string
without any escaping, but the filter function sees the user input
escaped. For instance, if user's input is "domain with
space<TAB>" then the filtering function gets "domain\ with\
space" as user's input but completer returns "domain with space".
Since these two strings don't match the filtering function
removes this candidate from the list. What we need to do is to
escape strings before calling the filtering function. This way,
the filtering function will see two same strings.

On readline completion vshReadlineCompletion() is called which
does nothing more than calling rl_completion_matches() with
vshReadlineParse() as a callback. This means, that
vshReadlineParse() is called repeatedly, each time returning next
completion candidate, until it returns NULL which is interpreted
as the end of the list of candidates.
The function takes two parameters: @text which is a portion of
input line around cursor when TAB was pressed, and @state. The
@state is an integer that is zero on the very first call and
non-zero on each subsequent call (in fact, readline does @state++
on each call).
Anyway, the idea is that the callback gets the whole list of
candidates on @state == 0 and returns one candidate at each call.
And this is what vshReadlineParse() is doing but some variables
(@partial, @cmd and @opt) are really used only in the @state == 0
case but declared for whole function. We can limit their scope by
declaring them inside the @state == 0 body which also means that
they don't have to be static anymore.
