41c73f66bc storage: move flag setting after declarations 2013-02-24 18:11:40 +01:00

448c93cf98 run: license as LGPL
It makes no sense to prohibit reuse of the wrapper in other LGPL
projects, since most of libvirt is designed to be LGPL.  Of
course, when using the wrapper to wrap a GPL program, the combined
result is still effectively GPL, but that shouldn't force us to
license the wrapper as GPL in isolation.

* run.in: Relicense to LGPLv2+.

1e54685fc7 qemu_migration: Cancel running jobs on failed migration
If a migration fails, we need to stop all block jobs running so
qemu doesn't try to send data to destination over and over again.

ae21b9bde6 qemu_migration: Stop NBD server at Finish phase
At the end of migration, it is important to stop NBD
server and thus release all allocated resources.

7b7600b3e6 qemu_migration: Introduce qemuMigrationDriveMirror
This function does the source part of NBD magic. It
invokes drive-mirror on each non shared and RW disk with
a source and wait till the mirroring process completes.
When it does we can proceed with migration.

Currently, an active waiting is done: every 500ms libvirt
asks qemu if block-job is finished or not.  However, once
the job finishes, qemu doesn't report its progress so we
can only assume if the job finished successfully or not.
The better solution would be to listen to the event which
is sent as soon as the job finishes. The event does
contain the result of job.

86d90b3abd qemu_migration: Introduce qemuMigrationStartNBDServer()
We need to start NBD server and feed it with all non-<shared/>,
RW and source-full disks. Moreover, with new virPortAllocator we
must ensure the borrowed port for NBD server will be returned if
either migration completes or qemu process is torn down.

f1748e34e2 qemu: Introduce nbd-server-stop command
This will be used after all migration work is done
to stop NBD server running on destination.  It
doesn't take any arguments, just issues a command.

is done in later patches.

121d4cfb9a Introduce NBD migration cookie
This migration cookie is meant for two purposes. The first is to be sent
in begin phase from source to destination to let it know we support new
implementation of VIR_MIGRATE_NON_SHARED_{DISK,INC} so destination can
start NBD server. Then, the second purpose is, destination can let us
know, on which port the NBD server is running.

e9a6704f99 qemu: Introduce NBD_SERVER capability

383ebc4694 Add support for <option> tag in network config
This patch adds support for a new <option>-Tag in the <dhcp> block of
network configs, based on a subset of the fifth proposal by Laine
Stump in the mailing list discussion at
https://www.redhat.com/archives/libvir-list/2012-November/msg01054.html.
Any such defined option will result in a dhcp-option=<number>,"<value>"
statement in the generated dnsmasq configuration file.

Currently, DHCP options can be specified by number only and there is
no whitelisting or blacklisting of option numbers, which should
probably be added.

2795813c69 run: use portable shell
Nothing in run required bash, except for the shebang.  On systems
where /bin/bash doesn't exist (I hit it on FreeBSD), using /bin/sh
instead fixes a 'make check' failure:
gmake[3]: Entering directory `/usr/home/dummy/libvirt/python'
  GEN    check-local
/usr/local/bin/bash: ../run: /bin/bash: bad interpreter: No such file or directory

* run.in: Use /bin/sh, not bash.

c2092abfb9 storage: use f_frsize, not f_bsize, for calculating available space
The bfree and blocks fields are supposed to be in units of frsize.  We were
calculating capacity correctly using those units, but the available
calculation was using bsize instead.  Most file systems report these as the
same value specifically because many programs are buggy, but that is no
reason to rely on that behavior, or to behave inconsistently.

This bug has been present since e266ded (2008) and aa296e6c, when the code
was originally introduced (the latter via cut and paste).

82d5fe5437 qemu: check backing chains even when cgroup is omitted
https://bugzilla.redhat.com/show_bug.cgi?id=896685 points out
a regression caused by commit 38c4a9c - libvirt only labels
the backing chain if the backing chain cache is populated, but
the code to populate the cache was only conditionally performed
if cgroup labeling was necessary.

* src/qemu/qemu_cgroup.c (qemuSetupCgroup): Hoist cache setup...
* src/qemu/qemu_process.c (qemuProcessStart): ...earlier into
caller, where it is now unconditional.
