create a separate macro with a _FULL suffix while those that do not

Implement a --timestamp option for 'virsh qemu-monitor-event', similar
to the one for 'virsh event'.
When the option is used, the human-readable timestamp will be printed
before the message, and the timing information provided by QEMU will
not be displayed.
memory_dirty_rate corresponds to dirty-pages-rate in QEMU and
memory_iteration is what QEMU reports in dirty-sync-count.

Commit id '3c7590e0a' added the flag to the rbd backend, but provided
no means via virsh to use the flag. This patch adds a '--delete-snapshots'
option to both the "undefine" and "vol-delete" commands.
For "undefine", the flag is combined with the "--remove-all-storage" flag
in order to add the appropriate flag for the virStorageVolDelete call;
whereas, for the "vol-delete" command, just the flag is sufficient since
it's only operating on one volume.
Currently only supported for rbd backends.
Instead of the custom error:
error: iothreadpin: invalid cpulist.
use vshCommandOptStringReq and let it report a more specific error:
error: Failed to get option 'cpulist': Option argument is empty
Adding this feature will allow users to easily attach a hostdev network
interface using PCI passthrough.
The interface can be attached using --type=hostdev and PCI address or
as --source. This command also allows you to tell, whether the interface

While parsing device addresses we should use correct base and don't
count on auto-detect. For example, PCI address uses hex numbers, but
each number starting with 0 will be auto-detected as octal number and
that's wrong. Another wrong use-case is for PCI address if for example
bus is 10, than it's incorrectly parsed as decimal number.
PCI and CCW addresses have all values as hex numbers, IDE and SCSI
addresses are in decimal numbers.

Although 0 length block jobs aren't entirely useful, the output of virsh
blockjob is empty due to the condition that suppresses the output for

Adds a new interface type using UDP sockets, this seems only applicable
to QEMU but have edited tree-wide to support the new interface type.
The interface type required the addition of a "localaddr" (local
address), this then maps into the following xml and qemu call.
<interface type='udp'>
<mac address='52:54:00:5c:67:56'/>
<source address='127.0.0.1' port='11112'>
<local address='127.0.0.1' port='22222'/>
</source>
<model type='virtio'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/>
</interface>
QEMU call:
-net socket,udp=127.0.0.1:11112,localaddr=127.0.0.1:22222
Notice the xml "local" entry becomes the "localaddr" for the qemu call.

When looking up a domain, we try to look up by ID, UUID and NAME
consequently while not really caring which of those lookups succeeds.
The problem is that if any of them fails, we dispatch the error from the
driver and that means setting both threadlocal and global error. Let's
say the last lookup (by NAME) succeeds and resets the threadlocal error as any
other API does, however leaving the global error unchanged. If the underlying
virsh command does not succeed afterwards, our cleanup routine in
vshCommandRun ensures that no libvirt error will be forgotten and that's
exactly where this global error comes in incorrectly.
# virsh domif-setlink 123 vnet1 up
error: interface (target: vnet1) not found
error: Domain not found: no domain with matching id 123
This patch also resets the global error which would otherwise cause some
minor confusion in reported error messages.

In order to share as much virsh' logic as possible with upcomming
virt-admin client we need to split virsh logic into virsh specific and
client generic features.
Since majority of virsh methods should be generic enough to be used by
other clients, it's much easier to rename virsh specific data to virshX
than doing this vice versa. It moved generic virsh commands (including info
and opts structures) to generic module vsh.c.
Besides renaming methods and structures, this patch also involves introduction
of a client specific control structure being referenced as private data in the
original control structure, introduction of a new global vsh Initializer,
which currently doesn't do much, but there is a potential for added
functionality in the future.
Lastly it introduced client hooks which are especially necessary during
client connecting phase.
This patch implements new virsh command, domrename.
Using domrename, it will be possible to rename domain from the virsh shell by
calling virRenameDomain API.
It takes two arguments, current domain name and new domain name.
Example:
virsh # list --all
Id Name State
----------------------------------------------------
- bar shut off
virsh # domrename bar foo
Domain successfully renamed
virsh # list --all
Id Name State
----------------------------------------------------
- foo shut off
virsh #

if (virStrToLong_ullp(token, NULL, 10, tmp) < 0) {

Rather than trying to fix the code, refactor the function again by
reusing virStringSplit.
We have a function parseRateStr() that parses --inbound and
--outbound arguments to both attach-interface and domiftune.
Now that we have all virTypedParams macros needed for QoS,
lets parse even floor attribute. The extended format for the
arguments looks like this then:
--inbound average[,peak[,burst[,floor]]]

The function is used to parse a tuple delimited by commas into
virNetDevBandwidth structure. So far only three out of fore
fields are supported: average, peak and burst. The single missing
field is floor. Well, the parsing works, but I think we can do
better. Especially when we will need to parse floor too in very
close future.

Reuse the vshBlockJobWait infrastructure to refactor cmdBlockCommit to
use the common code. This additionally fixes a bug when working with
new qemus, where when doing an active commit with --pivot the pivoting
would fail, since qemu reaches 100% completion but the job doesn't
switch to synchronized phase right away.
Introduce helper function that will provide logic for waiting for block
job completion so the 3 open coded places can be unified and improved.
This patch introduces the whole logic and uses it to fix
cmdBlockJobPull. The vshBlockJobWait function provides common logic for
block job waiting that should be robust enough to work across all
previous versions of libvirt. Since virsh allows passing user-provided
strings as paths of block devices we can't reliably use block job events
for detection of block job states so the function contains a great deal
of fallback logic.
Use the VSH_EXCLUSIVE_OPTIONS to exclude combinations of --pivot and
--keep-overlay and refactor the enforcing of the --wait option and other
flags that imply --wait.
Use the VSH_EXCLUSIVE_OPTIONS_VAR to interlock incompatible options.
Since a variable named 'abort' would conflict with older compilers use
VSH_EXCLUSIVE_OPTIONS for the --abort option.
There's this condition:
flags & VIR_DOMAIN_AFFECT_CURRENT && virDomainIsActive(dom)
which can never be true since VIR_DOMAIN_AFFECT_CURRENT has hardcoded
value of zero. Therefore virDomainIsActive() is a dead code. However,
the condition could make sense if it is rewritten as the following:
!(flags & VIR_DOMAIN_AFFECT_CONFIG) && virDomainIsActive(dom)
