Introduce 'global hypervisor parameters' support

Remove the KVM_MIGRATION_PORT param

Since this is easily configurable at run-time, we remove the
configure-time parameter. If anyone is building custom packages, then
the default can be tweaked by a one-line patch to

Note that this also fixes the type of parameter, the default from...

Add new “daemon-util” script to start/stop Ganeti daemons

Until now, Ganeti started and stopped its own daemons using custom functions.
To start, the daemon was just executed and then sent the appropriate signals to
stop it again. Init scripts would have to pay attention to the PID file and...

kvm console: use socat raw mode with escape

If this is enabled at configure time, we pass in different parameters to
the socat console, making it a lot more manageable.

Migration: add check for listening target

This patch adds a check for listening on the remote port in Xen and KVM
migrations. This will be generating a single “load of migration failed”

hypervisors: switch to using HV_MIGRATION_PORT

This changes KVM to use HV_MIGRATION_PORT instead of KVM_MIGRATION_PORT
and enables passing the port for Xen migrations.

Since KVM_MIGRATION_PORT is not used anymore, we stop exporting it from

Introduce HV_MIGRATION_PORT hypervisor parameter

This parameter will replace the direct use of KVM_MIGRATION_PORT and the
implicit use of the Xen migration port.

While it doesn't make sense to change this at instance level, we don't
have any other infrastructure for cluster-wide hypervisor parameters, so...
