72519f7331 docs: document iface-* commands
I intentionally set things up so 'virsh help interface' lists
commands in alphabetical order, but 'man virsh' lists them in
topical order; this matches our practice on some other commands.

* tools/virsh.pod: Document all iface commands.
* tools/virsh.c (ifaceCmds): Sort.

The new flags allow to pick current state, config or the live
parameter, with current being the existing API default (0).
This also hooks this to --config, --live, --current parameters for
the memtune virsh command

0ad06c1116 setmaxmem: add the new options to "virsh setmaxmem" command
This patch adds the new options (--live, --config, and --current) to
"virsh setmaxmem" command. The behavior of above options is the same
as that of "virsh setmem".  When the --config option is specified, a
modification is effective for the persistent domain, while the --live
option is specified, a modification is effective for an active
domain. The --current option is specified, it affects a current
domain.

This patch adds the new option (--current) to the "virsh setmem" command.
When --current option is specified, it affects a "current" domain.
The word "current" denotes that if a domain is running, it affects
a running domain only; otherwise it affects a persistent domain.

a73bbfc8be qemu: Remove the managed state file only if restoring succeeded
1) Both "qemuDomainStartWithFlags" and "qemuAutostartDomain" try to
restore the domain from managedsave'ed image if it exists (by
invoking "qemuDomainObjRestore"), but it unlinks the image even
if restoring fails, which causes data loss. (This problem exists
for "virsh managedsave dom; virsh start dom").

The fix for is to unlink the managed state file only if restoring
succeeded.

2) For "virsh save dom; virsh restore dom;", it can cause data
corruption if one reuse the saved state file for restoring. Add
doc to tell user about it.

3) In "qemuDomainObjStart", if "managed_save" is NULL, we shouldn't
fallback to start the domain, skipping it to cleanup as a incidental
fix. Discovered by Eric.

4591df766d Remove the Open Nebula driver
The Open Nebula driver has been unmaintained since it was first
introduced. The only commits have been for tree-wide cleanups.
It also has a major design flaw, in that it only knows about guests
that it has created itself, which makes it of very limited use.

Discussions wrt evolution of the VMWare ESX driver, concluded that
it should limit itself to single-node ESX operation and not try to
manage the multi-node architecture of VirtualCenter. Open Nebula
is a cluster like Virtual Center, not a single node system, so
the same reasoning applies.

The DeltaCloud project includes an Open Nebula driver and is a much
better fit architecturally, since it is explicitly targetting the
distributed multihost cluster scenario.

Thus this patch deletes the libvirt Open Nebula driver with the
recommendation that people use DeltaCloud for managing it instead.

* daemon/Makefile.am, daemon/libvirtd.c, src/Makefile.am: Remove

as well as that of active domains.

2169472ab6 qemu: Add shortcut for HMP pass through
Currently users who want to use virDomainQemuMonitorCommand() API or
it's virsh equivalent has to use the same protocol as libvirt uses for
communication to qemu. Since the protocol is QMP with current qemu and
HMP much more usable for humans, one ends up typing something like the
following:

    virsh qemu-monitor-command DOM \
'{"execute":"human-monitor-command","arguments":{"command-line":"info kvm"}}'

which is not a very convenient way of debugging qemu.

This patch introduces --hmp option to qemu-monitor-command, which says
that the provided command is in HMP. If libvirt uses QMP to talk with
qemu, the command will automatically be converted into QMP. So the
example above is simplified to just

    virsh qemu-monitor-command --hmp DOM "info kvm"

Also the result is converted from

    {"return":"kvm support: enabled\r\n"}

to just plain HMP:

    kvm support: enabled

If libvirt talks to qemu in HMP, --hmp flag is obviously a noop.

d9ad8ac392 Add VIR_DIV_UP to divide memory or storage request sizes with round up
Use it in all places where a memory or storage request size is converted
to a larger granularity. This avoids requesting too small memory or storage
sizes that could result from the truncation done by a simple division.

This extends the round up fix in 6002e0406c
to the whole codebase.

Instead of reporting errors for odd values in the VMX code round them up.

Update the QEMU Argv tests accordingly as the original memory size 219200
isn't a even multiple of 1024 and is rounded up to 215 megabyte now. Change
it to 219100 and 219136. Use two different values intentionally to make
sure that rounding up works.

Update virsh.pod accordingly, as rounding down and rejecting are replaced
by rounding up.

f15cad2916 Force guest suspend at timeout
If the memory of guest OS is changed constantly, the live migration
can not be ended ever for ever.

We can use the command 'virsh migrate-setmaxdowntime' to control the
live migration. But the value of maxdowntime is diffcult to calculate
because it depends on the transfer speed of network and constantly
changing memroy size. We need a easy way to control the live migration.

This patch adds the support of forcing guest to suspend at timeout.
With this patch, when we migrate the guest OS, we can specify a
timeout. If the live migration timeouts, auto-suspend the guest OS,
where the migration will complete offline.

dad4b5d47f Re-write virsh console to use streams
This re-writes the 'virsh console' command so that it uses
the new streams API. This lets it run remotely and/or as a

not just the first one.

a2943243c4 virsh: rework command parsing
Old virsh command parsing mashes all the args back into a string and
miss the quotes, this patches fix it. It is also needed for introducing
qemu-monitor-command which is very useful.

This patches uses the new vshCommandParser abstraction and adds
vshCommandArgvParse() for arguments vector, so we don't need
to mash arguments vector into a command sting.

And the usage was changed:
old:
virsh [options] [commands]

new:
virsh [options]... [<command_string>]
virsh [options]... <command> [args...]

So we still support commands like:
"define D.xml; dumpxml D" was parsed as a commands-string.

and support commands like:
we will not mash them into a string, we use new argv parser for it.

But we don't support the command like:
"define D.xml; dumpxml" was parsed as a command-name, but we have no such command-name.
