04c721f22d qemu: Always set async job when starting a domain
We only started an async job for incoming migration from another host.
When we were starting a domain from scratch or restoring from a saved
state (migration from file) we didn't set any async job. Let's introduce
a new QEMU_ASYNC_JOB_START for these cases.

2bf5333f45 qemu: Introduce qemuProcessIncomingDef
Incoming migration may require quite a few parameters (URI, fd, path) to
be considered while starting QEMU and we will soon add another one.
Let's group all of them in a single struct.

Introduce a new helper function "virDiskNameParse" which extends

A test is also added for this function testing both valid and

6472e54a98 libxl: implement virDomainMemorystats
Introduce support for domainMemoryStats API call, which
consequently enables the use of `virsh dommemstat` command to
query for memory statistics of a domain. We support
the following statistics: balloon info, available and currently
in use. swap-in, swap-out, major-faults, minor-faults require
cooperation of the guest and thus currently not supported.

We build on the data returned from libxl_domain_info and deliver
it in the virDomainMemoryStat format.

867f34a683 virSetUIDGID: Don't leak supplementary groups
The LXC driver uses virSetUIDGID() to become UID/GID 0.
It passes an empty groups list to virSetUIDGID()
to get rid of all supplementary groups from the host side.
But virSetUIDGID() calls setgroups() only if the supplied list
is larger than 0.
This leads to a container root with unrelated supplementary groups.
In most cases this issue is unoticed as libvirtd runs as UID/GID 0
without any supplementary groups.

ea542455b4 lxc: Don't make container's TTY a controlling TTY
Userspace does not expect that the initial console
is a controlling TTY. systemd can deal with that, others not.
On sysv init distros getty will fail to spawn a controlling on
/dev/console or /dev/tty1. Which will cause to whole container
to reboot upon ctrl-c.

This patch changes the behavior of libvirt to match the kernel
behavior where the initial TTY is also not controlling.

The only user visible change should be that a container with
bash as PID 1 would complain. But this matches exactly the kernel
be behavior with init=/bin/bash.
To get a controlling TTY for bash just run "setsid /bin/bash".

bd3e16a3cf locking: Add io_timeout to sanlock
https://bugzilla.redhat.com/show_bug.cgi?id=1251190

So, if domain loses access to storage, sanlock tries to kill it
after some timeout. So far, the default is 80 seconds. But for
some scenarios this might not be enough. We should allow users to
adjust the timeout according to their needs.

d3fa510a75 storage: Don't assume storage pool exists for FC/SCSI refresh thread
https://bugzilla.redhat.com/show_bug.cgi?id=1277781

The virStoragePoolFCRefreshThread had passed a pointer to the pool obj
in the virStoragePoolFCRefreshInfoPtr; however, we cannot assume that
the pool exists still since we don't keep the pool lock throughout
the duration of the thread.

Therefore, instead of passing the pool obj pointer, pass the UUID of
the pool and perform a lookup.  If found, then we can perform the
refresh using the locked pool obj pointer; otherwise, we just exit
the thread since the pool is now gone.
