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”
message for KVM, but otherwise not prevent the migration. For Xen (which...

TLMigrateInstance: add error messagess during Exec

Currently the migration of an instance doesn't show any error until the
end. We add two messages that show better the progress:

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...

hypervisors: change MigrateInstance API

Currently the $hypervisor.MigrateInstance takes the instance name. This
patch changes it to take the instance object, such that other instance
properties (especially hvparams) are available to it.

Revert the instance IP conflicts

Since instances can live in different VLANs from nodes (especially in
routed mode), based on the 'link' parameter, we shouldn't always
restrict having duplicate IPs. Thus we only check the node IPs/cluster
IP for now.

Introduce a wrapper for hostname resolving

Currently a few of the LU's CheckPrereq use utils.HostInfo which raises
a resolver error in case of failure. This is an exception from the
standard that CheckPrereq should raise an OpPrereqError if the error is
in the 'pre' phase (so that it can be retried)....

Add a configuration verify check for duplicate IPs

Workaround fake failures in drbd+live migration

This patch is an attempt to fix the ugly issue during migration:
Cannot resync disks on node …: [True, 100]

If my understanding is correct, sometimes we poll the /proc/drbd file at
an inoportune moment, while it's being updated, or while the DRBD device...
