Latest QEMU versions support various migration capabilities. Each
can be enabled/disabled with 'migrate_set_capability' monitor
command.

(2.10) Fix conflict between virtio + spice or soundhw

With regard to PCI slot occupied by a KVM instance we have
observed the following:

1) Slot 0 will always be Host bridge.
2) Slot 1 will always be ISA bridge.
3) Slot 2 will always be VGA controller (even with -display none)....

(2.10) Fix bitarray ops wrt PCI slots

Introduce new method `_GetFreeSlot()` responsible only for bitarray
operations. It fixes search in case of bitarray is either '0000..'
or '1111..'.

Use it instead of `_UpdatePCISlots()` and in `_GetFreePCISlot()`.

ifdown: Use new methods to unconfigure NICs

We unconfigure a NIC (invoke ifdown script) during:

  • instance cleanup
  • finalizing successful migration on source node
  • hot-unplugging a NIC

In case of migration we do only a local cleanup.

ifdown: Use new methods to create NIC files

NIC files containing corresponding tap name are created during:

  • instance startup
  • NIC hot-add

For compatibility we continue creating indexed based NIC files along
with uuid based ones.

ifdown: Make Read/LoadKVMRuntime classmethods

.. and make LoadKVMRuntime() take instance_name rather than the
whole instance object as first argument. This will be needed during
instance cleanup where we the instance object is not available.

We are going to retrieve current NIC configuration from the runtime...

ifdown: Introduce _UnconfigureNIC() helper method

This method takes a NIC object, creates the proper invironment
and invokes ifdown script.

It takes an extra boolean argument only_local which is passed
to ifdown script as the second positional argument. It states...

ifdown: Extract env creation from ConfigureNic()

Introduce new helper method that creates the environment passed
to ifup/ifdown scripts. Instance tags and NIC index will be passed
only during ifup script since only then are available and
valid. Both can change until a NIC gets removed and thus will not...

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...

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
