a54f25a946 virsh-domain: Refactor error paths for cmdCPUStats
This patch fixes the following issues in the cpu-stats virsh command:

1) Renames label failed_params to no_memory to match coding style
2) Uses proper typed parameter cleanup in error paths to avoid leaks
3) Adds a ret variable and simplifies error labels
4) Changes error message to a slightly more descriptive one and gets rid
   of the newline at the end:

Before:
$ virsh cpu-stats tr
error: Failed to virDomainGetCPUStats()

error: Requested operation is not valid: domain is not running

After:
$ tools/virsh cpu-stats tr
error: Failed to retrieve CPU statistics for domain 'tr'
error: Requested operation is not valid: domain is not running

3d1596b048 Introduce an LXC specific public API & library
This patch introduces support for LXC specific public APIs. In
common with what was done for QEMU, this creates a libvirt_lxc.so
library and libvirt/libvirt-lxc.h header file.

The actual APIs are

  int virDomainLxcOpenNamespace(virDomainPtr domain,
                                int **fdlist,
                                unsigned int flags);

  int virDomainLxcEnterNamespace(virDomainPtr domain,
                                 unsigned int nfdlist,
                                 int *fdlist,
                                 unsigned int *noldfdlist,
                                 int **oldfdlist,
                                 unsigned int flags);

which provide a way to use the setns() system call to move the
calling process into the container's namespace. It is not
practical to write in a generically applicable manner. The
nearest that we could get to such an API would be an API which
allows to pass a command + argv to be executed inside a
container. Even if we had such a generic API, this LXC specific
API is still useful, because it allows the caller to maintain
the current process context, in particular any I/O streams they
have open.

NB the virDomainLxcEnterNamespace() API is special in that it
runs client side, so does not involve the internal driver API.

462a69621e build: use common .in replacement mechanism
We had several different styles of .in conversion in our Makefiles:
ALLCAPS, @ALLCAPS@, @lower@, ::lower::
Canonicalize on one form, to make it easier to copy and paste
between .in files.

Also, we were using some non-portable sed constructs: \@ is an
undefined escape sequence (it happens to be @ itself in GNU sed,
but POSIX allows it to mean something else), as well as risky
behavior (failure to consistently quote things means a space
in $(sysconfdir) could throw things off; also, Autoconf recommends
using | rather than , or ! in the s||| operator, because | has to
be quoted in shell and is therefore less likely to appear in file
names than , or !).

Fix all of these uses to follow the same syntax.

* daemon/libvirtd.8.in: Switch to @var@.
* tools/virt-xml-validate.in: Likewise.
* tools/virt-pki-validate.in: Likewise.

8b9bf7879b Add support for offline migration
Offline migration transfers inactive definition of a domain (which may
or may not be active). After successful completion, the domain remains
in its current state on source host and is defined but inactive on
destination host. It's a bit more clever than virDomainGetXMLDesc() on
source host followed by virDomainDefineXML() on destination host, as
offline migration will run pre-migration hook to update the domain XML
on destination host. Currently, copying non-shared storage is not
supported during offline migration.

Offline migration can be requested with a new migration flag called
VIR_MIGRATE_OFFLINE (which has to be combined with
VIR_MIGRATE_PERSIST_DEST flag).

bf72095954 virsh: Report errors if arguments of the schedinfo command are incorrect
Libvirt's helper API's when called directly don't raise the error so
that virsh remembers it. Subsequent calls to libvirt API's might reset
the error.

In case of schedinfo virDomainFree() in the cleanup section resets the
error when virTypedParameterAssignFromStr() fails.

This patch adds function vshSaveLibvirtError() that can be called after
calling libvirt helper APIs to ensure the error is remembered.

snapshots, such as offline external).

2cd4d8e506 virsh: add snapshot-create-as memspec support
External checkpoints could be created with snapshot-create, but
without libvirt supplying a default name for the memory file,
it is essential to add a new argument to snapshot-create-as to
allow the user to choose the memory file name.  This adds the
option --memspec [file=]name[,snapshot=type], where type can
be none, internal, or external.  For an example,

virsh snapshot-create-as $dom --memspec /path/to/file

is the shortest possible command line for creating an external
checkpoint, named after the current timestamp.

* tools/virsh-snapshot.c (vshParseSnapshotMemspec): New function.
(cmdSnapshotCreateAs): Use it.
* tests/virsh-optparse (test_url): Test it.
* tools/virsh.pod (snapshot-create-as): Document it.

9d91a18ebf virsh: make ,, escape parsing common
So far, none of the existing callers of vshStringToArray expected
the user to ever pass a literal comma; meanwhile, snapshot parsing
had rolled its own array parser.  Moving the comma escaping into
the common function won't affect any existing callers, and will make
this function reusable for adding memory handling to snapshot parsing.

As a bonus, the testsuite was already testing snapshot parsing, so
the fact that the test still passes means that we are now giving
testsuite exposure to vshStringToArray.

* tools/virsh-snapshot.c (vshParseSnapshotDiskspec): Move ,,
parsing...
* tools/virsh.c (vshStringToArray): ...into common function.
Also, vshStrdup can't fail.

5f75bd4bbe snapshot: Add flag to enable creating checkpoints in live state
The default behavior while creating external checkpoints is to pause the

space saving for creating the memory save image while the guest is live
to minimize downtime.

This patch adds a flag that causes the guest not to be paused before
taking the snapshot.

def31e4c58 qemu: fix attach/detach of netdevs with matching mac addrs
This resolves:

   https://bugzilla.redhat.com/show_bug.cgi?id=862515

which describes inconsistencies in dealing with duplicate mac
addresses on network devices in a domain.

(at any rate, it resolves *almost* everything, and prints out an
informative error message for the one problem that isn't solved, but
has a workaround.)

A synopsis of the problems:

1) you can't do a persistent attach-interface of a device with a mac
address that matches an existing device.

2) you *can* do a live attach-interface of such a device.

3) you *can* directly edit a domain and put in two devices with
matching mac addresses.

4) When running virsh detach-device (live or config), only MAC address
is checked when matching the device to remove, so the first device
with the desired mac address will be removed. This isn't always the
one that's wanted.

5) when running virsh detach-interface (live or config), the only two
items that can be specified to match against are mac address and model
type (virtio, etc) - if multiple netdevs match both of those
attributes, it again just finds the first one added and assumes that
is the only match.

Since it is completely valid to have multiple network devices with the
same MAC address (although it can cause problems in many cases, there
*are* valid use cases), what is needed is:

1) remove the restriction that prohibits doing a persistent add of a
netdev with a duplicate mac address.

2) enhance the backend of virDomainDetachDeviceFlags to check for
something that *is* guaranteed unique (but still work with just mac
address, as long as it yields only a single results.

This patch does three things:

1) removes the check for duplicate mac address during a persistent
netdev attach.

2) unifies the searching for both live and config detach of netdevices
in the subordinate functions of qemuDomainModifyDeviceFlags() to use the
new function virDomainNetFindIdx (which matches mac address and PCI
address if available, checking for duplicates if only mac address was
specified). This function returns -2 if multiple matches are found,
allowing the callers to print out an appropriate message.

Steps 1 & 2 are enough to fully fix the problem when using virsh
attach-device and detach-device (which require an XML description of
the device rather than a bunch of commandline args)

3) modifies the virsh detach-interface command to check for multiple
matches of mac address and show an error message suggesting use of the
detach-device command in cases where there are multiple matching mac
addresses.

Later we should decide how we want to input a PCI address on the virsh
commandline, and enhance detach-interface to take a --address option,
eliminating the need to use detach-device

* src/conf/domain_conf.c
* src/conf/domain_conf.h
* src/libvirt_private.syms
  * added new virDomainNetFindIdx function
  * removed now unused virDomainNetIndexByMac and
    virDomainNetRemoveByMac

* src/qemu/qemu_driver.c
  * remove check for duplicate max from qemuDomainAttachDeviceConfig
  * use virDomainNetFindIdx/virDomainNetRemove instead
    of virDomainNetRemoveByMac in qemuDomainDetachDeviceConfig

    in qemuDomainUpdateDeviceConfig

* src/qemu/qemu_hotplug.c

    qemuDomainDetachNetDevice.

ab54581549 virsh: Remove --flags from nodesuspend
We always expose individual bits from flags as separate options rather
than exposing a raw flags options. Since virNodeSuspendForDuration does
not currently support any flags, the only way of using this --flags
options that would not fail is "--flags 0", which is equivalent to
omitting the option. Thus it is highly unlikely anyone would actually be
using it and removing it should be safe.

fe7872827f virsh: new net-update command
This command uses the new virNetworkUpdate() API to modify an existing
network definition, and optionally have those modifications take
effect immediately without restarting the network.

An example usage:

  virsh net-update mynet add-last ip-dhcp-host \
   "<host mac='00:11:22:33:44:55' ip='192.168.122.45'/>" \
   --live --config

If you like, you can instead put the xml into a file, and call like
this:

  virsh net-update mynet add ip-dhcp-host /tmp/myxml.xml
   --live --config

virsh will autodetect whether the argument is itself an xml element,
or if it's a file, by looking at the first character - the first
character of an xml element is always "<", and the first character of
a file is almost always *not* "<" (in the rare case that it is, the
user could specify "./<filename...").

A --parent-index option is also available (to give the index within a
list of parent objects, e.g. the index of the parent <ip> element when
updating ip-dhcp-host elements), but is optional and at least for now
will probably be used rarely.

--live, --config, and --current options - if you specify --live, only
the live state of the network will be updated. If you also specify
--config, then the persistent configuration will also be updated;
these two commands can be given separately, or both together. If you
don't specify either (you can optionally specify "--current" for the
same effect), then the "current" config will be updated (i.e. if the
network is active, then only its live config is affected, but if the
network is inactive, only the persistent config is affected).

chain is committed.  Existing 'virsh blockjob' commands can then
track the status, change the bandwidth, or abort the commit job.

With a bit more on the command line, 'virsh blockcommit $dom $disk
--wait --verbose' can be used for blocking behavior, with visual
feedback on the overall status, and can be canceled with Ctrl-C.

The overall design, including the wait loop logic, borrows heavily
from the existing blockpull command.

51907779ee virsh: Update only changed scheduler tunables
When setting the cpu tunables in virsh you are able to update only a
subset of them. Virsh while doing the update updated all of the
tunables, changed ones with new values and unchanged with old ones.
This is unfortunate as it:
a) might overwrite some other change by a race condition (unprobable)
b) fails with range checking as some of the old values saved might be
   out of range

This patch changes the update procedure so that only the changed value
is updated on the host.

This patch also fixes a very unprobable memory leak if the daemon would
return a string tunable parameter, as the typed parameter array was not
cleared.

Most likely this problem arose because of the patch I pushed
in gnulib commit e07d7c40f3ca5ec410cf5aa6fa03cfe51e712039.
Previously, gnulib required timeval's tv_sec to be
the same size as time_t.  But now, it requires only that
tv_sec be big enough to hold a time_t.

This patch was needed for Emacs.  Without the patch, gnulib
replaced struct timeval on OpenBSD, and this messed up
utimens.c, and Emacs wouldn't build.

Alternatively, gnulib could substitute its own struct timeval
for the system's, wrapping every struct timeval-using function
(gettimeofday, futimesat, futimes, lutimes, etc.  That'd be
more work, though.  And it would introduce some performance
issues with gettimeofday, which is supposed to be fast.

I've been trying to get away from using struct timeval,
and to use the higher-resolution struct timespec instead,
so messing with these obsolescent interfaces has been
lower priority for me.  But if someone wants to take the
more-ambitious approach that'd be fine, I expect.

For this particular case, though, how about if we avoid
the problem entirely?  libvirt doesn't need to use struct
timeval here at all.  It makes libvirt smaller and probably
faster, and it ports to OpenBSD without messing with gnulib.

70e608918e virsh: Improve checking for connection when running commands
Almost each virsh command uses the function vshConnectionUsability
before doing anything, to check if the connection is "alive".  Commands
that don't need an conection are already conveniently marked with
VSH_CMD_FLAG_NOCONNECT. We can automaticaly check for the connection
before calling any remote command so we don't forget to do so.

This patch also upgrades the connection check to use virConnectIsAlive
along with the current approach.

output, but maybe this can be a starting point for someone.

79ca7e4e57 libvirt-guests: systemd host shutdown does not work
I originally postet this into the Fedora bugzilla
https://bugzilla.redhat.com/show_bug.cgi?id=843836

Currently gracefully shutting down guest vms on host shutdown does not work on
Fedora 17, the guests are killed hard on system shutdown.

The reason is systemd considers libvirt-guests.service to be stopped when the
system is running:

$ systemctl status libvirt-guests.service
libvirt-guests.service - Suspend Active Libvirt Guests
          Loaded: loaded (/usr/lib/systemd/system/libvirt-guests.service;
enabled)
          Active: deactivating (stop) since Fri, 27 Jul 2012 15:47:31 +0200;
2min 48s ago
         Process: 1085 ExecStart=/etc/init.d/libvirt-guests start
(code=exited, status=0/SUCCESS)
         Control: 1150 (libvirt-guests)
          CGroup: name=systemd:/system/libvirt-guests.service
                  └ control
                    ├ 1150 /bin/sh /etc/init.d/libvirt-guests stop
                    └ 2257 sleep 1

libvirt-guests.service is defined as type "simple" in systemd (the default).
That means systemd will shut down the service when the start executable is
terminated after starting is done. Systemd will not call stop again on system
shutdown because it thinks it is already stopped.

The solution is to define it as type "oneshot" and set the flag
"RemainAfterExit". Then systemd will consider the service as active after
startup and will call the stop function on host shutdown.

a4bcefbcff maint: Use consistent copyright.
This is a follow up patch of commit f9ce7dad6, it modifies all
the files which declare the copyright like "See COPYING.LIB for
the License of this software" to use the detailed/consistent one.

And deserts the outdated comments like:

 * libvirt-qemu.h:
 * Summary: qemu specific interfaces
 * Description: Provides the interfaces of the libvirt library to handle
 *              qemu specific methods
 *
 * Copy:  Copyright (C) 2010, 2012 Red Hat, Inc.

Uses the more compact style like:

2751ab289b virsh: Fix error resetting on fallback paths
On some fallback paths in virsh, error reported by the previously failed
API is cleared by virResetLastError() that doesn't free error stored by
virsh. This patch changes this to clear it using vshResetLibvirtError().

3df9626c40 virsh: Refactor error clearing on graceful fallback paths
Virsh uses an error handler to save errors from libvirt. On some code
paths it's needed to clear libvirt errors and continue on fallback code
paths without reporting failure.

This patch adds function vshResetLibvirtError() that clears error
returned by libvirt and updates all places where the old two-line method
was used.

dcfb7050c4 virsh: Check for existence of storage before undefining the domain
When undefining a domain and removing associated storage using "virsh
undefine --storage" the domain was at first undefined and after that the
storage removal proces was started. If the user specified an invalid
disk to remove, the error could not be corrected.

This patch moves enumeration and filtering of volumes that should be
removed before the domain is undefined, but the removal process is still
kept after the domain has been undefined.

bc80977144 Fixup manpage names and copyright dates
The copyright dates in the manpages haven't been updated in awhile.

Also, when pod2man converts a pod file into a manpage, it will only
remove the extension from the filename if it is ".pod". Some of the
libvirt pod files are named *.pod.in, and that filename is placed
unchanged into the manpage. This patch uses pod2man's --name option to
fix that.

Believe it or not, there's even a BZ for this:
