Although there already was an effort (b620bdee) to replace vshPrint occurrences
with vshPrintExtra due to '--quiet' flag, there were still some leftovers. So
this patch fixes them, hopefully for good.

There were a few places in our virsh* code where instead of calling vshError
on failure we called vshPrint.

First, since commit 834c5720 the error reporting within the vshErrorHandler
doesn't work because there was a lot of renaming going on (dull mechanical
renaming without much thinking about it, yep - shame on me) and so the original
env variable VIRSH_DEBUG got renamed to VSH_DEBUG which we don't support nor
document anywhere. Second, by specifying this env variable, the last libvirt
error gets reported twice despite the fact we say the error reporting should be
deferred until the command finishes, and last but not least the vintage code's
logic is a bit 'odd', since the error would get reported iff the env variable
is set, even if the value should be equal to our DEFAULT value in which case it
doesn't make sense that we behave differently when an env variable is set to
some value and when there's no env variable at all but we use the same value
automatically as default.

Unlike the other error messages in vshInitDebug, this one relied on a hardcoded

After 06a7b1ff4 the @&opts_need_arg is not used anywhere. Well,
it is set but never read:

Commit id 'dcfdf341' passes 'opts_need_arg' and 'opts_seen' to
vshCmddefGetData, but that seems to be incorrect as those values
are not initialized properly (something at least one compiler found).
Instead the static 'const_opts_need_arg' and 'const_opts_seen' values
should be passed.
By passing unitialized values leads to not finding possible options
for simpler commands (domfsfreeze for example), where if you're in
a virsh shell using command line completion - you'll get a list of
files in your current directory instead of two options --domain and
--mountpoint (as would happen with this patch applied.

Since we're using autoconf to substitute the right value in
Makefile.am now, we can use a less generic name without running
into circular dependencies.
Adding $(prefix) in Makefile.am, as we were doing, means that
it would be prepended even when using --with-ws-plugindir,
which is something we don't want to happen.
Instead, we add it beforehand but take care that it doesn't
get expanded until make is called.

If the VM is offline virsh attempted to at least report the pinning
information for the VM. This would not work properly now that the vcpus
can be sparse. Fix it by getting the vcpu states from the XML.
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1375920
The fallback code used if virDomainGetVcpusFlags is not supported used
wrong XPath queries and basically did not work at all. Fix them to point
to the <domain> <vcpu> element instead of <vcpus> which was not present
until lately.
The Requires relationship is very strong, in that it prevents
a unit from running unless all the units it Requires are
running as well.
This turns out to be a problem because we want to be able to
restart libvirtd at any time without having libvirt-guests
suspend or shutdown running guests.
Turn the Requires relationship into a Wants relationship:
this way starting libvirt-guests will cause systemd to (attempt
to) start libvirtd as well, but stopping or restarting libvirtd
will not alter libvirt-guests' running state.
1. Move the declaration of const vshCmdDef *help - it should be at the
top of the "if" rather than in the middle.
2. Change a comparison from && to || - without doing so we could crash
on commands like 'virsh list' which would allow completion of some
non -- option based on whatever was found in the current working
directory and then as soon as that was completed, the next <tab>
would crash since "opt" would be returned as NULL, but the check
was dereferencing "&& opt->type"
3. Before dereferencing opt->completer, be sure opt isn't NULL.
With newer versions of libvirt Domain-0 is again visible in the list of
running guests but it should not be considered as a guest for shutdown
or suspend.
Signed-off-by Stefan Bader <stefan.bader@canonical.com>
The list file expects all guest UUIDs on the same line as the URI
which the guests run on. This does not happen when the list is
echo'ed in quotes. When stripping the quotes, newlines get transformed
into spaces. Without this, only the first guest on the list is actually
handled.

Introduced by commit id '834c5720'.
During the code motion and creation of vsh.c, the function 'vshDeinit()'
in the (new) vsh.c was altered from whence it came in virsh.c such that
calling 'vshReadlineDeinit(ctl)' was conditional on "ctl->imode".
This causes a problem for the interactive running if the "quit" and "exit"
commands are used because 'cmdQuit' will clear ctl->imode, thus when the
interactive loop in main() of virsh.c exits because ctl->mode is clear and
virshDeinit is called which calls vshDeinit, the history file is now not
written. Conversely, if one had exited the interactive loop via pressing
<ctrl>D the file would be created because loop control is broken on EOF
and ctl->imode is not set to false.
This patch will remove the conditional call to vshReadlineDeinit and
restore the former behaviour.
Commit 6c504d6a added a note to the virsh man page about the
deprecation of 'cap' and 'weight' settings for the credit
scheduler. To this day, the default scheduler in Xen is credit
and it supports setting 'cap' and 'weight'. Remove the deprecation
notice from the note on the Xen credit scheduler.

Change the logic in a way, so that VSH_CMD_FLAG_ALIAS behaves similarly to
how VSH_OT_ALIAS for command options, i.e. there is no need for code duplication
for the alias and the aliased command structures. Along with that change,
switch any existing VSH_CMD_FLAG_ALIAS occurrences to this new format. Also,
since this patch introduces a new command structure element, adjust the
virsh-self-test test to make sure we won't ever miss to specify the '.alias'
member for an aliased command because doing that would lead to an internal
error.

Originally introduced by commit 2432521e which correctly split
vshCmddefOptParse into command's options validation and options parsing.
However, command's 'internals' are not tied solely to .options, rather it
should be about the overall structure, therefore the validation should be
extracted from vshCmddefOptParse and performed only within our test suite, i.e.
in vshSelfTest.
