2bbda1444d libvirt-guest.init: handle domain name with spaces
awk splits the line on consecutive spaces, which breaks getting the name

2d70a46911 setmem: add the new options to "virsh setmem" command
This patch adds the new options (--live and --config)  to "virsh setmem" command.
The behavior of above options is the same as that of "virsh setvcpus" and so on.
That is, when the --config option is specified, a modification is effective for
the persistent domain. Moreover we can modify the memory size of inactive domains
as well as that of active domains.

d03f199595 virsh: Change option parsing functions to return tri-state information
This is needed to detect situations when optional argument was
specified with non-integer value: '--int-opt foo'. To keep functions
uniform vshCommandOptString function was also changed, because it
returns tri-state value as well. Given result pointer is updated only
in case of success. If parsing fails, result is not updated at all.

2ed6cc7bec Expose event loop implementation as a public API
Not all applications have an existing event loop they need
to integrate with. Forcing them to implement the libvirt
event loop integration APIs is an undue burden. This just
exposes our simple poll() based implementation for apps
to use. So instead of calling

   virEventRegister(....callbacks...)

The app would call

   virEventRegisterDefaultImpl()

And then have a thread somewhere calling

    static bool quit = false;
    ....
    while (!quit)
      virEventRunDefaultImpl()

6db98a2d4b build: don't require pod2man for tarball builds
Right now, 'man libvirtd' includes information that depends on
configure results, so it must be generated on the fly and live
in $(builddir); however, requiring pod2man on all end user
machines is overkill.  Meanwhile, 'man virsh' doesn't mention
any configure results, so it can be built at 'make dist' time.
If that situation changes in the future, we can generate virsh.1
in the same way that we generate libvirtd.8.

* daemon/Makefile.am (libvirtd.8.in): New rule, to run pod2man in
advance of distribution.
(libvirtd.8): Use only sed from tarball.
(EXTRA_DIST): Ship new file.
(libvirtd.pod): Delete unused rule.
(man8_MANS): Let automake know which section to use.
(CLEANFILES, MAINTAINERCLEANFILES): Adjust to new files.
* tools/Makefile.am (dist_man1_MANS): Distribute pre-built man
pages, fine since they don't require any substitution.
(virt-xml-validate.1, virt-pki-validate.1): Change input source.

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.

8e6d9860cd Cancel migration if user presses Ctrl-C when migration is in progress
While migration is in progress and virsh is waiting for its
completion, user may want to terminate the progress by pressing
Ctrl-C. But virsh just exits on user's Ctrl-C leaving migration
in background that user isn't even aware of. It's not reasonable.

This patch changes the behaviour for migration. For other
commands Ctrl-C still terminates virsh itself.

4d0350fc38 Remove bogus port handling code in virsh
The "find-storage-pool-sources-as" command takes two arguments,
a hostname and a port number. For some reason the code would
also then look for a port number appended to the hostname
string by searching for ':'. This totally breaks if the user
gives an IPv6 address, and is redundant, since you can already
provide a port as a separate argument

38afe8f5ec build: fix autobuild failures on gcov upgrade
Last time I ran ./autobuild.sh was on F13; and upgrading to F14
exposed these leftovers due to a newer gcov than what was in the stale

981d2cdab4 maint: improve i18n on non-Linux
Per the gettext developer:
http://lists.gnu.org/archive/html/bug-gnu-utils/2010-10/msg00019.html
http://lists.gnu.org/archive/html/bug-gnu-utils/2010-10/msg00021.html

gettext() doesn't work correctly on all platforms unless you have
called setlocale().  Furthermore, gnulib's gettext.h has provisions
for setting up a default locale, which is the preferred method for
libraries to use gettext without having to call textdomain() and
override the main program's default domain (virInitialize already
calls bindtextdomain(), but this is insufficient without the
setlocale() added in this patch; and a redundant bindtextdomain()
in this patch doesn't hurt, but serves as a good example for other
packages that need to bind a second translation domain).

This patch is needed to silence a new gnulib 'make syntax-check'
rule in the next patch.

8e3051af84 replace last instances of close()
I am replacing the last instances of close() I found with VIR_CLOSE() / VIR_FORCE_CLOSE respectively.

The first part patches virsh, which I missed out on previously.

The 2nd patch I had left out intentionally to look at it more carefully:
The 'closed' variable could be easily removed since it wasn't used anywhere else. The possible race condition that could result from the filedescriptor being closed and not set to -1 (and possibly let us write into 'something' totally different if the fd was allocated by another thread) seems to be prevented by the qemuMonitorLock() already placed around the code that reads from or writes to the fd. So the change of this code as shown in the patch should not have any side-effects.

  "Failed to disconnect from the hypervisor"

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
non-root user. This requires that virsh be linked against
the simple event loop from libvirtd in daemon/event.c
As an added bonus, it can now connect to any console device,
not just the first one.

* tools/Makefile.am: Link to event.c
* tools/console.c, tools/console.h: Rewrite to use the
  virDomainOpenConsole() APIs with streams

attention. I hope I payed attention in all the right places... Please
have a look. This should have at least solved one more double-close
error.
