Erik Skultety 834c5720e4 tools: Introduce new client generic module vsh
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.

Michal Privoznik f69ece073e virsh: Teach cmdFreepages to work with lxc driver
Some drivers don't expose available huge page sizes in the
capabilities XML. For instance, LXC driver is one of those.
This has a downside that when virsh is trying to get
aggregated info on free pages per all NUMA nodes, it fails.
The problem is that the virNodeGetFreePages() API expects
caller to pass an array of page sizes he is interested in.
In virsh, this array is filled from the capabilities from
'/capabilities/host/cpu/pages' XPath. As said, in LXC
there's no such XPath and therefore virsh fails currently.
But hey, we can fallback: the page sizes are exposed under
'/capabilities/host/topology/cells/cell/pages'. The page
size can be collected from there, and voilà the command
works again. But now we must make sure that there are no
duplicates in the array passed to the public API. Otherwise
we won't get as beautiful output as we are getting now.

Andrea Bolognani 815dc963ee virsh: Move error messages inside vshCommandOpt*() functions 2015-06-02 09:20:31 -04:00
Andrea Bolognani be6ff4da95 virsh: Pass vshControl to all vshCommandOpt*() calls
This will allow us to use vshError() to report errors from inside
vshCommandOpt*(), instead of replicating the same logic and error
messages all over the place.

We also have more context inside the vshCommandOpt*() functions,
for example the actual value used on the command line, which means
we can produce more detailed error messages.

vshCommandOptBool() is the exception here, because it's explicitly
designed not to report any error.

Hao Liu 12bd207e21 Fix invalid log, misused option types and a typo
This patch fixes the following issues.

1)  When an invalid wwn is introduced, libvirt reports
    "Malformed wwn: %s". The template won't be replaced.

2)  "target" option for dompmsuspend and "xml" option for
    save-image-define are required options and should use
    VSH_OT_DATA instead of VSH_OT_STRING as an option type.

3)  A typo.
