Regression introduced in 0.8.5, commit c1564268. The command
'virsh freecell 0' quit working when it changed from an optional
string to an optional integer.
This patch introduces a slight change that specifying an option
twice is now detected as an error. It also changes things so
that a command that has more than 1 required option will not
complain about missing options if one but not all of the options
were given in long format, as in 'virsh vol-create --pool p file',
as well as making positional parsing work for all optional
options (each positional argument is associated with the earliest
option that has not yet been seen by name).
Optional boolean options can appear before required argument
options, because they don't affect positional argument parsing,
and obviously a required boolean option makes no sense.
Technically, this patch renders VSH_OT_STRING and VSH_OT_DATA
redundant; but cleaning that up can be a separate patch.
No command should ever need more than 32 options, right? :)
* tools/virsh.c (vshCmddefGetData, vshCmddefGetOption)
(vshCommandCheckOpts): Alter parameters to use bitmaps.
(vshCmddefOptParse): New function.
(vshCommandParse): Update for better handling of positional
arguments.
(vshCmddefHelp): Allow unit tests to validate options.
The current state of virsh parsing is that:
$ virsh vol-info /path/to/image
$ virsh vol-info --pool default /path/to/image
$ virsh vol-info --pool default --vol /path/to/image
all lookup the volume by path (technically, the last two also attempt
a name lookup within a pool, whereas the first skips that step, but
the end result is the same); meanwhile:
$ virsh vol-info default /path/to/image
complains about unexpected data. Why? Because the --pool option is
optional, so default was parsed as the --vol argument, and
/path/to/image.img doesn't match up with any remaining options that
require an argument. For proof, note that:
$ virsh vol-info default --vol /path/to/image
complains about looking up 'default' - the parser mis-associated both
arguments with --vol. Given the above, the only way to specify pool
is with an explicit "--pool" argument (you can't specify it
positionally). However, named arguments can appear in any order, so:
$ virsh vol-info /path/to/image --pool default
$ virsh vol-info --vol /path/to/image --pool default
have also always worked. Therefore, this patch has no functional
change on vol-info option parsing, but only on 'virsh help vol-info'
synopsis layout. However, it also allows the next patch to 1) enforce
that required options are always first (without this patch, the next
patch would fail the testsuite), and 2) allow the user to omit the
"--pool" argument. That is, the next patch makes it possible to do:
$ virsh vol-info /path/to/image default
which to date was not possible.

optional cellno requires --cellno.
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.

When the new maximum memory size becomes less than the current memory size,
I think it is not the libvirt client but the each driver that decides the behavior
(reject the operation or shrink the current memory size).

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.
Commit 78ba748ef1 claims to fix
documentation for swap_hard_limit virsh memtune option but it only fixes
documentation in formatdomain.html and libvirt.h. This patch completes
the task by fixing "virsh help memtune" output and memtune section of
virsh man page.

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.

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.

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

The app would call
virEventRegisterDefaultImpl()
And then have a thread somewhere calling
static bool quit = false;

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

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.
* src/fdstream.c (virFDStreamOpenFile, virFDStreamCreateFile):
Use VIR_FORCE_CLOSE instead of close.

* src/util/util.c (__virExec): Special case preservation of std

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.
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.
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.

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).

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.
The event watches need to be removed before the event loop
terminates, otherwise they cause a dangling reference to
be held on the virStreamPtr, which in turns holds a reference
on virConnectPtr, which in turn causes errors like
"Failed to disconnect from the hypervisor"
* tools/console.c: Remove watches before event loop quits
* tools/virsh.c: Print out dangling reference count
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
* tools/virsh.c: Support choosing the console name

* tools/virsh.c (vshParseArgv): Use NULL instead of 0 for pointer,
and symbolic names for has_arg. Give --version an optional arg.
(vshUsage): Document this.
* tools/virsh.pod: Likewise.
Using automated replacement with sed and editing I have now replaced all
occurrences of close() with VIR_(FORCE_)CLOSE() except for one, of
course. Some replacements were straight forward, others I needed to pay
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.
