Commit e962a57 added 'attach-disk --shareable', even though we
already had 'attach-disk --mode=shareable'. Worse, if the user
types 'attach-disk --mode=readonly --shareable', we create
non-sensical XML. The best solution is just to undocument the
duplicate spelling, by having it fall back to the preferred
spelling.
* tools/virsh-domain.c (cmdAttachDisk): Let alias handling fix our
mistake in exposing a second spelling for an existing option.
* tools/virsh.pod: Fix documentation.

In commit b46c4787dd I changed the code to
watch long running jobs in virsh. Unfortunately I didn't take into
account that poll may get a hangup if the terminal is not a TTY and will
be closed.
This patch avoids polling the STDIN fd when there's no TTY.
'--print-xml' option is very useful for doing some test.
But we had to specify a real domain for it.
This patch could enable us to specify a fake domain
when using --print-xml option.

It's possible to create a domain which will only use a TLS port
and will not have a non-TLS port set by using:
<graphics type='spice' autoport='yes' defaultMode='secure'/>
In such a setup, the 'graphics' node for the running domain will be:
<graphics type='spice' tlsPort='5900'
autoport='yes' listen='127.0.0.1'
defaultMode='secure'>
However, cmdDomDisplay loops over all the 'graphics' node, and it
ignores nodes which don't have a 'port' attribute. This means
'virsh domdisplay' will only return an empty string for domains
as the one above.
This commit looks for both 'port' and 'tlsPort' before deciding
to ignore a graphics node. It also makes sure 'port' is not printed
when it's not set.
This makes 'virsh domdisplay' return
'spice://127.0.0.1?tls-port=5900' for domains using only a TLS
port.

Some systems apparently have a global variable/function called remove
and thus break compilation of virsh-domain.c. Rename the variable to
avoid this.
Reported by GuanQiang.
Since the maxvcpus command query the maximum number of virtual
CPUs supported for a guest VM on this connection, it should be
in virsh-host.c but not virsh-domain.c.

Commit 38ab1225 changed the default value of ret from true to false but
forgot to set ret = true when job is NONE. Thus, virsh domjobinfo
returned 1 when there was no job running for a domain but it used to
(and should) return 0 in this case.
The VIR_FREE() macro will cast away any const-ness. This masked a
number of places where we passed a 'const char *' string to
VIR_FREE. Fortunately in all of these cases, the variable was not
in fact const data, but a heap allocated string. Fix all the
variable declarations to reflect this.

The vshWatchJob function registers a SIGINT handler that is used to
abort the active job and does not terminate virsh. Unfortunately, this
breaks when using the ssh transport as SIGINT is sent to the foreground
process group including the ssh transport processes which terminate.
This breaks the connection and migration is left in a insane state.
With this patch the terminal is modified to ignore key binding that
sends SIGINT and does the handling manually.

Use the new semantics of vshStringToArray to avoid leaking the array of
volumes to be deleted. The array would be leaked in case the first
volume was found in the domain definition. Also refactor the code a bit
to sanitize naming of variables hoding arrays and dimensions of the
arrays.

Currently the virConnectBaselineCPU API does not expose the CPU features
that are part of the CPU's model. This patch adds a new flag,
VIR_CONNECT_BASELINE_CPU_EXPAND_FEATURES, that causes the API to explicitly

When cdrom is block type, the virsh change-media failed to insert

Paolo Bonzini pointed out that it's actually possible to migrate a qemu
instance that was paused due to I/O error and it will be able to work on
the destination if the storage is accessible.
This patch introduces flag VIR_MIGRATE_ABORT_ON_ERROR that cancels the
migration in case an I/O error happens while it's being performed and
allows migration without this flag. This flag can be possibly used for
other error reasons that may be introduced in the future.
This patch fixes changes done in commit 29c1e913e4
that was pushed without implementing review feedback.
The flag introduced by the patch is changed to VIR_DOMAIN_VCPU_GUEST and
documentation makes the difference between regular hotplug and this new
functionality more explicit.
The virsh options that enable the use of the new flag are changed to
"--guest" and the documentation is fixed too.
This flag will allow to use qemu guest agent commands to disable
(offline) and enable (online) processors in a live guest that has the
guest agent running.
Because it's a valid combination. p2p still uses a separate channel
for qemu migration, so there's value in letting the user specify a manual
migrate URI for overriding auto-port, or libvirt's FQDN lookup.
What _isn't_ allowed is --migrateuri and TUNNELLED, since there is
no separate migration channel. Disallow that instead
