70f8299285 ch: Report VIR_DRV_FEATURE_NETWORK_UPDATE_HAS_CORRECT_ORDER as supported
Even though the CH driver doesn't implement virNetworkUpdate()
API, when it does it will see the arguments in correct order.
This is similar to other drivers that don't implement the API,
like ESX, libxl, LXC, etc. Enabling this driver feature stops
clients from swapping the arguments (see comment in the API for
more info).

83cf648ced ch_process: Check whether domain is already running before starting it
There are two places where a domain can be started in CH driver:
chDomainCreateXML() and chDomainCreateWithFlags(). Both acquire a
job (good), but neither of them checks whether the domain isn't
already running. This is wrong. Fortunately, both function call
the very same virCHProcessStart() rendering it the best place for
such check.

22a96eac7c ch_driver: Introduce and use virCHDomainRemoveInactive()
There are few places where a call to virDomainObjListRemove() is
guarded with !vm->persistent check. And there are some places
which are missing this check completely (leading us to losing a
domain). To prevent such mistakes introduce
virCHDomainRemoveInactive() which does the check for us. Also
replace all occurrences of virDomainObjListRemove() with the call
to the new function.

31ef66f12e ch_driver: Don't lock driver when getting version
In chConnectGetVersion() the CH driver is locked in order to read
driver->version. This is needless, because not only is the
version set with driver unlocked (chStateInitialize() calls
chExtractVersion() which sets the version), but the version is
practically immutable. Once driver initialized itself it's never
changed.

105dace22c Revert "report error when virProcessGetStatInfo() is unable to parse data"
This reverts commit 938382b60ae5bd1f83b5cb09e1ce68b9a88f679a.

Turns out, the commit did more harm than good. It changed
semantics on some public APIs. For instance, while
qemuDomainGetInfo() previously did not returned an error it does
now. While the calls to virProcessGetStatInfo() is guarded with
virDomainObjIsActive() it doesn't necessarily mean that QEMU's
PID is still alive. QEMU might be gone but we just haven't
realized it (e.g. because the eof handler thread is waiting for a
job).

8eb4461645 remove sysconfig files
sysconfig files are owned by the admin of the host. They have the
liberty to put anything they want into these files. This makes it

Remove the sysconfig file and place the current desired default into

Local customizations can now go either into /etc/sysconfig/name
or /etc/systemd/system/name.service.d/my-knobs.conf

Attempt to handle upgrades in libvirt.spec.
Dirty files which are marked as %config will be renamed to file.rpmsave.
To restore them automatically, move stale .rpmsave files away, and
catch any new rpmsave files in %posttrans.
