ifdown: Introduce helper methods

Until now Ganeti upon TAP creation, a NIC file was created
under $RUNDIR/kvm-hypervisor/nic/<instance_name>/<nic_index>

Since NICs have obtained a UUID, we are going to create another
file named after its UUID. This will be needed during ifdown...

Change kvm-if* scripts

  • Rename kvm-vif-bridge to kvm-ifup-custom
  • Search if /etc/ganeti/kvm-if*-custom is available
    and execute it instead
  • Pass positional argument to custom script

Add example kvm-ifdown script

This script currently does nothing more that calling user the
user provided one if it exists.

User provided script should be placed under /etc/ganeti/
and named `ganeti-kvm-ifdown`.

(kvm) Hotplug a device found only in config.data

A device can be added only in config.data by omitting `--hotplug`
option. With this patch we allow this device to be hot-plugged
in the future by issuing `gnt-instance modify --net <index>: --hotplug`
command. HotModDevice() will search the runtime entry of the device...

(2.10) Workaround for monitor bug related to greeting msg

QMP may return multiple greeting messages upon connection.
This is reported on qemu-devel. The fix is one-liner but
until it get's released this is a quick and dirty workaround
that flushes the client's buffer after getting the first...

(2.10) hotplug: Verify if a command succeeded or not

Just after issuing _CallHoplugCommands() we invoke
_VerifyHotplugCommand() which parses `info pci` result
and searches for given PCI slot and device id.

If we previously had removed a device but it is still there...

(2.10) hotplug: Each hotplug qemu commmand with a separate socat

Previously we issued one socat command with two "\n" separated
actions (e.g. netdev_add ...\ndevice_add...)

After having observed a strange monitor behavior [1] splitting
those commands and introducing a sleep time in between, may reduce...

(2.9) Gracefully handle degraded instances in verification

The current code assumes that every instance either is of type
diskless or has at least one disk. However, with the option to
remove individual disk degraded 0-disk non-diskless instances
can occur. While such instances usually are not useful, Ganeti...

(2.9) Preserve disk basename on instance rename

For file-based instances, upon rename, the directory containing
the instance disks is moved. Therefore, the basename needs to
be preserved in this case. Fix this. Note that so far, this
worked by accident as before 94e252a3 file names used to be...

(2.9) Be aware of the degraded case when cleaning up an instance

In the case of a degraded file-based instance, the file storage directory
for that instance cannot be obtained by looking at the first disk. Use
the standard location, computed from first principles, in this case....
