The 'virsh man' description of send-key was incomplete and used the
old style (literal 'optional name' instead of '[name]' metasyntax).
Meanwhile, none of the other virsh help texts include examples, so
I moved it out of virsh help and into the man page.
* tools/virsh.pod (send-key): Give better details.
* tools/virsh.c (info_send_key): Drop example from here.
There have been several instances of people having problems with
a broken managed save file, and not aware that they could use
'virsh managedsave-remove dom' to fix things. Making it possible
to do this as part of starting a domain makes the same functionality

Knowing whether 'virsh start' will resume a saved image or do
a fresh boot is useful enough to expose via 'virsh list'.
Also, translate the state column.
* tools/virsh.c (cmdList): add --managed-save flag
* tools/virsh.pod (list): Document it.
Based on a suggestion by Miklos Vajna.
Call me lazy, but:
virsh qemu-monitor-command dom --hmp info status
is nicer than:
virsh qemu-monitor-command dom --hmp 'info status'
* tools/virsh.c (cmdQemuMonitorCommand): Allow multiple arguments,
for convenience.
Down the road, I want to add virDomainSnapshotGetParent, and use
the new API rather than xml scraping; but this virsh command can
be implemented even without the new API.
* tools/virsh.c (cmdSnapshotParent): New command.
* tools/virsh.pod (snapshot-parent): Document it.
Sometimes, full XML is too much; since most snapshot commands
operate on a snapshot name, there should be an easy way to get
at the current snapshot's name. For example:
virsh snapshot-revert dom `virsh snapshot-current dom --name`
* tools/virsh.c (cmdSnapshotCurrent): Add an option.
* tools/virsh.pod (snapshot-current): Document it.
The description of the list command seemed to suggest that it could
take a set of domains as an argument, which is not correct in the
current HEAD. If virsh list is intended to take a list of domains,
then this patch should be NAK'd and a bug opened against virsh list.
Reported by hachi on #virt
v2:
Change language to include transient domains
Osier pointed out that transient domains are not defined, so what I
had originally proposed wasn't quite correct.
Rename the existing --current flag to the new name --active,
while adding a new flag --current to expose the new
VIR_DOMAIN_AFFECT_CURRENT flag of virDomainGetVcpusFlags.
For backwards compability, the output does not change (even
though the label "current" no longer matches the spelling of
the option that would trigger that number in isolation), and
we accept "--current --live" as an undocumented synonym for
"--active --live" to avoid breaking any existing clients.
* tools/virsh.c (cmdVcpucount): Add --active flag, and rearrange
existing flag handling to expose VIR_DOMAIN_AFFECT_CURRENT support.
* tools/virsh.pod (vcpucount): Document this.
Now you can edit a saved state file even if you forgot to grab
a dumpxml file prior to saving a domain. Plus, in-place editing
feels so much nicer.
* tools/virsh.c (cmdSaveImageDumpxml, cmdSaveImageDefine)
(cmdSaveImageEdit): New commands.
* tools/virsh.pod (save-image-dumpxml, save-image-define)
(save-image-edit): Document them.
Also, migrate was missing documentation for the --xml option
added in commit ec5301cb.
* tools/virsh.c (cmdSave, cmdRestore): Add xml argument.
* tools/virsh.pod (save, restore, migrate): Document it.
Wire up the new flag to several virsh commands. Also, the
'dump' command had undocumented flags.
* tools/virsh.c (cmdSave, cmdManagedSave, cmdDump, cmdStart)
(cmdRestore): Add new flag.
* tools/virsh.pod (save, managedsave, dump, start, restore):
Document flags.
If the domain has managed save image, and --managed-save is
not specified, then it fails with an error telling the user
that a managed save image still exists.
If the domain has managed save image, and --managed-save is
specified, it invokes virDomainUndefineFlags. If
virDomainUndefineFlags fails, then it tries to remove the managed
save image using virDomainManagedSaveRemove first, with
invoking virDomainUndefine following. (For compatibility between
new virsh with this patch and older libvirt without this patch).
Similarly if the domain has no managed save image. See the codes for
detail.
NOTE: Have not removing the codes checking if the domain is running
in function "cmdUndefine", it will go along with qemu driver's fix
(allow to undefine a running domain).
* tools/virsh.c: new column "Managed save" for "cmdDominfo".
* tools/virsh.pod: Update document of "managedsave" to tell one can
use "dominfo" to query whether a domain has any managed save image.
We can make the virsh migrate UI friendlier by supplying the
missing bit automatically instead of erroring out when requesting
--tunnelled without --p2p.
* tools/virsh.c (doMigrate): Make --p2p optional when using
--tunnelled.
* tools/virsh.pod (migrate): Tweak wording accordingly.
"optional" is not a very good meta-syntactic construct in our man
page. I scrubbed this, and additionally improved some documentation
on mutually exclusive options. For example,
[[--live] [--config] | [--current]]
implies a set of optional flags, where within the set you can have
either --current or a choice of 0, 1, or both --live and --config.
* tools/virsh.pod: Use "[name]" rather than "optional name" for
optional arguments.
This adds four options for virsh command attach-disk.
--cache option allows user to specify cache mode of disk device
from virsh command line when attaching a disk device.
--serial option allows user to specify serial string of disk device
from virsh command line when attaching a disk device.
--shareable option allows user to specify whether the disk device is
shareable between domains when attaching a disk device from virsh
command line.
--address option allows user to specify address of disk device when
attaching a disk device.
This patch adds the --current option to "virsh setvcpus"
command. Currently "virsh setvcpus" command supports
"--live" and "--config" , but "--current" option.
From view of consistency, it's reasonable to support
"--current" option too.
When --current is specified, it affects a "current"
domain.

If an application is using libvirt + KVM as a piece of its
internal infrastructure to perform a specific task, it can
be desirable to guarentee the VM dies when the virConnectPtr
disconnects from libvirtd. This ensures the app can't leak
any VMs it was using. Adding VIR_DOMAIN_START_AUTOKILL as
a flag when starting guests enables this to be done.
* include/libvirt/libvirt.h.in: All VIR_DOMAIN_START_AUTOKILL
* src/qemu/qemu_driver.c: Support automatic killing of guests

When resetting vcpupin setting, we have to specify all host physical

When using vcpupin command, we have to speficy comma-separated list as cpulist,
but this is tedious in case the number of phsycal cpus is large.
This patch improves this by introducing special markup "-" and "^" which are
similar to XML schema of "cpuset" attribute.
The example:
# virsh vcpupin Guest 0 0-15,^8
is identical to
# virsh vcpupin Guest 0 0,1,2,3,4,5,6,7,9,10,11,12,13,14,15
NOTE: The expression is sequentially evaluated, so "0-15,^8" is not identical

This patch adds the new option (--live, --config and --current) to
"virsh vcpupin" command. The behavior of above aption is the same as
that of "virsh setmem", "virsh setvcpus", and whatnot.
When the --config option is specified, the command affects a persistent
domain, while --live option is specified, it affects a running (live) domain.
The --current option cannot be used with --config or --live at the same
time, and when --current is specified, it affects a "current" domain.
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
* include/libvirt/libvirt.h.in: defines the new flags
* tools/virsh.c: adds support at virsh level
* tools/virsh.pod: updates virsh documentation

This patch adds the new options (--live, --config, and --current) to

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

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.

the persistent domain. Moreover we can modify the memory size of inactive domains
as well as that of active domains.

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.
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.
The virt-mem program is no longer shipped, but was still being

BZ# 639603:
https://bugzilla.redhat.com/show_bug.cgi?id=639603
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.
To ease debugging this trivial patch allows to find what was compiled
in in the local version of libvirt, this doesn't work for remote access
but that's probably sufficient. With the patch I get on my machine:

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.

Call me lazy: some shells use exit (e.g. sh), others use quit (e.g. ftp),

Common Unix practice is to prefer VISUAL over EDITOR, particularly if
the editor of choice spawns a new window. Thus, it is also common to
see settings like EDITOR='emacs -nw', with the expectation that the
shell will parse this as an argument to 'emacs' and not try to invoke
a file containing a space.
If a user puts junk in EDITOR, they deserve what they get (much more
than virsh will misbehave); furthermore, sudo scrubs EDITOR by
default. So the blind use of metacharacters in EDITOR should not be
considered too much of a security issue.
* tools/virsh.c (editFile): Prefer VISUAL over EDITOR. Don't
