For compatibility reasons virDomainSetVcpus needs to add vcpus as non
hotpluggable which means that the users will not be able to unplug it
after the VM has started. Add a flag that will allow to tell the API
that the unpluggable vcpus are okay.

The NSS module shouldn't rely on custom leases database to not have
entries for leases which have expired.

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.

Make use of the new recently introduced alias handling for virt-admin srv-*
commands.
Signed-off-by: NErik Skultety <eskultet@redhat.com>

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.

Recent changes extracted the command internals validation routine from

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.

If the initial check is true the function immediately returns so there's no
need to enclose the code following the check within an 'else' block.
Also, by removing the 'else' block, the declarations need to be moved to
beginning of the function block to conform with our guidelines.

The intention is to move vshCmddefCheckInternals out of vshCmddefOptParse to
our test suite. First step to do that is to enforce checking for an existing
help string (that also means it's non-empty) in a command because a command
without a help is not much of a use.

virsh maxvcpus --type kvm output is useless on PPC. Also, in
commit e6806d79 we documented not rely on virConnectGetMaxVcpus
output. Fix the  maxvcpus to use virConnectGetDomainCapabilities
now to make it useful. The call is made to use the default emulator
binary and to check for the host machine and arch which is what the
command intends to show anyway.

When using
virsh net-event non-existing-net
the error message says that 'either --list or event type is required'
This is misleading as 'virsh net-event $valid-event-type' is not going
to work either. What is expected is 'virsh net-event --event
$valid-event-type'

This commit fixes the string in pool-event, nodedev-event, event, and
net-event.

This patch is to delete the extra wrap "\n" after failed vol-resize
error for both "Failed to change size of volume to" and "Failed to change
size of volume by". For error with wrap, there will be an extra wrap
between two errors, such as:

   (1)# virsh vol-resize --pool default --vol vol-test 5M
        error: Failed to change size of volume 'vol-test' to 5M

        error: invalid argument: Can't shrink capacity below current capacity unless shrink flag explicitly specified

   (2)# virsh vol-resize /var/lib/libvirt/images/volds --shrink --delta 10M
        error: Failed to change size of volume 'volds' by 10M

        error: invalid argument: can't shrink capacity below existing allocation

Unfortunately, commit a8962f70 only fixed first half of the reported issue of
virt-admin outputting negative values where unsigned int is expected by
BZ below, so this commit represents the other missing half of the fix.

This patch changes the signature of vshCompleters, allowing to pass along

we might want to pass the autocomplete vshControl along with the

Having After=libvirtd.service merely ensures that, if both
services are asked to start, libvirtd.service will start
first.

What we really want is for libvirtd.service to be started
whenever libvirt-guests.service is asked to start. Adding a
Requires= relationship guarantees that will happen.

We use a separate line for each After= relationship in other
unit files: do the same here for consistency's sake, and also
to make future changes nicer to diff

libvirt-guests.service does both suspend *and* resume guests,
depending on whether it's being started or stopped: the
description should reflect this, to avoid confusing messages
during startup.

Replace "active" with "running" (to match virsh list's output)
and don't capitalize libvirt.

When we wanted to break huge and unmaintainable virsh into
smaller files first thing we did was to just move funcs into
virsh-.c files and then #include them from virsh. Having it done
this way we also needed to have them listed under EXTRA_DIST.
However, things got changed since then and now all the virsh-*.c
files are proper source files. Therefore they are listed under
virsh_SOURCES too. But for some reason we forgot to remove them
from EXTRA_DIST.

virVcpuInfo contains the vcpu number that the data refers to. Report
what's returned by the daemon rather than the sequence number as with
sparse vcpu topologies they won't match.

If virBufferError() reports an error, then vshError() is needed to
report the error situation instead of a simple vshError().

Use the full versions of the message, instead of composing a base
message with what was updated; the change makes the messages properly
translatable, since different parts of a sentence might need different
declensions for example.
