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: 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: 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: 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...

    and execute it instead
  • Pass positional argument to custom script

(ext) Override disk_cache hvp with disk param in ext

This is a hack that brings disk_cache hypervisor param
at disk level. This is supported only for disks of ext
template that allow arbitrary params. The corresponding
param that should be used is 'cache'....

(ext) Pass disk geometry in kvm command

Currently we allow this feature only for ext templates that
allow arbitrary params per disk. If both 'heads' and 'secs'
params are given then 'cyls' is calculated from the disk size.

TODO: export these params in IDISK_PARAMS since the can be...

(grnet) Move disk options before nic ones in kvm command

Older versions of Ganeti did ensure that during startup
disk devices will be inserted before nic devices in PCI
configuration space. KVM inserts devices to PCI slots
depending on the order of command line options....

(2.13) kvm: Add migration capabilities as an hvparam

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