When undefining a VM with storage the man page doesn't explicitly
mention that the volumes need to be a part of the storage pool otherwise
it won't work.
Adding output to 'virsh --version=long' makes it easier to
tell if a distro built with particular libraries (it doesn't
tell you what a remote libvirtd is built with, but is still
better than nothing). But we forgot to mention gluster.

In the 'directory' and 'netfs' storage pools, a user can see
both 'file' and 'dir' storage volume types, to know when they
can descend into a subdirectory. But in a network-based storage
pool, such as the upcoming 'gluster' pool, we use 'network'
instead of 'file', and did not have any counterpart for a
directory until this patch. Adding a new volume type
'network-dir' is better than reusing 'dir', because it makes
it clear that the only way to access 'network' volumes within
that container is through the network mounting (leaving 'dir'
for something accessible in the local file system).

This patch shuts up the following warning of clang
on Mac OS X:
virsh.c:2761:22: error: assigning to 'char *' from 'const char [6]' discards qualifiers
[-Werror,-Wincompatible-pointer-types-discards-qualifiers]
rl_readline_name = "virsh";
^ ~~~~~~~
The warning happens because rl_readline_name on Mac OS X comes
from an old readline header that still uses 'char *', while it
is 'const char *' in readline 4.2 (April 2001) and newer.
Tested on Mac OS X 10.8.5 (clang-500.2.75) and Fedora 19 (gcc 4.8.1).

There were two separate places with that were stringifying type of a
volume. One of the places was out of sync with types implemented
upstream.
To avoid such problems in the future, this patch adds a common function
to convert the type to string and reuses it across the two said places.
Add an extra space before the first column as we have when listing
domains.

The 'vcpucount' command is a getter command for the vCPUu count. When
one or more of the filtering flags are specified the command returns the
value only for the selected combination. In this case the --live and
--config combination isn't valid. This however didn't cause errors as
the combination of flags was rejected by the libvirt API but then the
fallback code kicked in and requested the count in a way where the clash
of the flags didn't matter.
Mark the flag combination mutually exclusive so that users aren't
confused.

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.
Unconditional use of getenv is not secure in setuid env.
While not all libvirt code runs in a setuid env (since
much of it only exists inside libvirtd) this is not always
clear to developers. So make all the code paranoid, even

for libxml2 and libselinux.

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.

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

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.
Resoves: https://bugzilla.redhat.com/show_bug.cgi?id=983348
This patch adds instrumentation to allow modification of config of the
terminal in virsh and successful reset of the state afterwards.
The added helpers allow to disable receiving of SIGINT when pressing the
key sequence (Ctrl+C usualy). This normally sends SIGINT to the
foreground process group which kills ssh processes used for transport of
the data.
When virBufferError is ok in cmdAttachDisk, the latter
should 'goto cleanup', instead of returning a false to
prevent memory leaking.

Noticed while reviewing another patch that had an accidental
mismatch due to refactoring. An audit of the code showed that
very few callers of vshCommandOpt were expecting a return of
-2, indicating programmer error, and of those that DID check,
they just propagated that status to yet another caller that
did not check. Fix this by making the code blatantly warn
the programmer, rather than silently ignoring it and possibly
doing the wrong thing downstream.
I know that we frown on assert()/abort() inside libvirtd
(libraries should NEVER kill the program that linked them),
but as virsh is an app rather than the library, and as this
is not the first use of assert() in virsh, I think this
approach is okay.

rather than error when ctrl-c interrupts job.

The virLoginShellAllowedUser method must not free the 'groups'
parameter it is given, as that is owned by the caller.
The virLoginShellAllowedUser method should be checking
'!*ptr' (ie empty string) rather than '!ptr' (NULL string)
since the latter cannot be true.

virt-login-shell.c was failing to compile with
CC virt_login_shell-virt-login-shell.o
virt-login-shell.c: In function 'main':
virt-login-shell.c:205:5: error: implicit declaration of function 'setlocale' [-Werror=implicit-function-declaration]
virt-login-shell.c:205:5: error: nested extern declaration of 'setlocale' [-Werror=nested-externs]
virt-login-shell.c:205:20: error: 'LC_ALL' undeclared (first use in this function)
Add a virt-login-shell binary that can be set as a user's
shell, such that when they login, it causes them to enter
the LXC container with a name matching their user name.

The VIR_DOMAIN_PAUSED_GUEST_PANICKED constant is badly named,
leaking the QEMU event name. Elsewhere in the API we use
'CRASHED' rather than 'PANICKED', and the addition of 'GUEST'
is redundant since all events are guest related.
Thus rename it to VIR_DOMAIN_PAUSED_CRASHED, which matches
with VIR_DOMAIN_RUNNING_CRASHED and VIR_DOMAIN_EVENT_CRASHED.
It was added in commit 14e7e0ae8d
which post-dates v1.1.0, so is safe to rename before 1.1.1

The VIR_DOMAIN_SHUTDOWN_CRASHED state constant does not appear
to be used in the QEMU code anyway. It also doesn't make much
(any) sense, since the 'shutdown' state is a transient state
between 'running' and 'shutoff' and when a guest crashes, it
does not end up in a 'shutdown' state, only 'shutoff'.
It was added in commit 14e7e0ae8d
which post-dates v1.1.0, so is safe to remove before 1.1.1

Noticed that the expected "not supported" error is dropped when
invoking 'virsh snapshot-list dom' on a Xen installation running
the libxl driver
virsh snapshot-list test
error: Invalid snapshot: virDomainSnapshotFree
The error is overwritten by a call to virDomainSnapshotFree
in cleanup code within cmdSnapshotList. Prevent overwritting
the real error by not calling virDomainSnapshotFree with a NULL
virDomainSnapshotPtr.
