fc3247f211 virsh: Use virBuffer for generating XML
cmdAttachInterface and cmdAttachDisk still used vshRealloc and sprintf
for generating XML, which is hardly maintainable. Let's get rid of this
old code.

dfec22cc60 virsh: Option for overriding disk type in attach-disk
Unless --driver tap|file option was given to attach-disk, virsh would
generate <disk type='block'> XML which might be fine for Xen but not for
other hypervisors. This patch introduces a new option --sourcetype which
can be used to explicitly set the type of disk source. The option
accepts either "file" or "block" types.

12a41822e1 virsh: remove driver check from attach-disk command
Virsh shouldn't check for driver support but rather let the backend handled this.
After removing the check, I can successfully attach file-based images to a qemu
VM with attach-disk.

% virsh attach-disk vm2 /images/test02.img vdc --driver qemu --type disk --subdriver raw
Disk attached successfully

This command generates the following XML:

<disk type='block' device='disk'>
      <driver name='qemu' type='raw'/>
      <source dev='/images/test02.img'/>
      <target dev='vdc' bus='virtio'/>
      <alias name='virtio-disk2'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x09' function='0x0'/>
</disk>

963a5b7a08 Make virsh setmaxmem balloon only when successful.
After playing around with virsh setmaxmem for a bit,
I ran into some surprising behavior; if a hypervisor does
not support the virDomainSetMaxMemory() API, but the value
specified for setmaxmem is less than the current amount
of memory in the domain, the domain would be ballooned
down *before* an error was reported.

To make this more consistent, run virDomainSetMaxMemory()
before trying to shrink; that way, if an error is thrown,
no changes to the running domain are made.

0cdff7b5e7 Fix up inconsistent virsh option error reporting.
The virsh option error reporting was not being used
consistently; some commands would spit out errors on
missing required options while others would just silently fail.
However, vshCommandOptString knows which ones are required
and which ones aren't, so make it spit out an error where
appropriate.  The rest of the patch is just cleaning up
the uses of vshCommandOptString to deal with the new error
reporting.

26752f3be1 virsh: tweak help output for VSH_OT_DATA
https://bugzilla.redhat.com/show_bug.cgi?id=609044 complained
that 'virsh help pool-create-as' didn't document the shortcut
that you can do 'virsh pool-create-as $name $type --target $target'
rather than having to supply the four optional source- arguments
in order to fill out the necessary positional arguments.

This one-liner changes the help output to hopefully make this more obvious:

  NAME
    pool-create-as - create a pool from a set of args

  SYNOPSIS
    pool-create-as <name> [--print-xml] <type> [<source-host>] [<source-path>] [<source-dev>] [<source-name>] [<target>] [--source-format <string>]

  DESCRIPTION
    Create a pool.

  OPTIONS
    [--name] <string>  name of the pool
    --print-xml      print XML document, but don't define/create
    [--type] <string>  type of the pool
    [--source-host] <string>  source-host for underlying storage
    [--source-path] <string>  source path for underlying storage
    [--source-dev] <string>  source device for underlying storage
    [--source-name] <string>  source name for underlying storage
    [--target] <string>  target for underlying storage
    --source-format <string>  format for underlying storage

* tools/virsh.c (vshCmddefHelp): Make it more obvious that data
arguments may, but not must, be specified by option leaders.

b221973a11 Add --source-format argument to virsh pool-define-as and pool-create-as
When creating pools from dedicated disks, the existing pool-define-as
and pool-create-as commands are a bit non-optimal.

Ideally, a person would be able to specify all of the required options
directly on the command line instead of having to edit the XML.

At the moment, there is no way to specify the format type (ie gpt) so it
gets included in the XML the pool is constructed with.

Please find attached a simple (tested) patch to add an optional
"--source-format 'type'" to virsh.  This is patched against current git
master and will apply cleanly.

Also created a Red Hat BZ ticket for this (#597790) for tracking.

b0a3f8b6c5 qemu: live migration with non-shared storage for kvm
Support for live migration between hosts that do not share storage was
added to qemu-kvm release 0.12.1.
It supports two flags:
-b migration without shared storage with full disk copy
-i migration without shared storage with incremental copy (same base image
shared between source and destination).

I tested the live migration without shared storage (both flags) for native
and p2p with and without tunnelling.  I also verified that the fix doesn't
affect normal migration with shared storage.

2b50cae54e Fix memory leaks in cmdInterfaceEdit and cmdNWFilterEdit.
This applies a fix to thos functions similar to that made to cmdEdit
in 270895063d, thus fnixing a memory
leak - if tmp is unlinked and NULLed early in the function, the memory
used by tmp is never freed. Since we will always unlink tmp prior to
freeing its memory at the end of the function, just remove the earlier
code and let cleanup: do the cleanup.
