It assumes UUIDs as an non optional slot in NIC object.

(2.10) Allow instances to obtain externally reserved IPs
The administrator should be able to assign an externally reserved IP
to a Ganeti instance manually, if desired. Currently this is not
supported. External reservations should act as holes in the pool and
not just as IPs already used by someone outside of Ganeti.
Automatic allocation with ip=pool will continue to exclude those IPs
as happens now.
To allow such functionality the administrator needs to pass explicitly
the desired IP along with the ``--no-conflicts-check`` option, or else
an error will be produced as happens now.
The aforementioned require the following changes:
- Make IsReserved() to look either in reservations or external ones.
- Make Reserve() and Release() to use IsReserved() with external
argument True or False.
- Pass extra option to ReserveIp() to bypass checking of external reservations
- Update man pages and design doc for this change.
Furthermore, a side effect of this patch is that it fixes the
following problem:
Currently, one could not mark an IP as external if it was already
reserved (i.e. belonged to an instance). The code would produce a warning
and fail silently.
Fix config_mock.py so that if network and ip is given then reserve it in

Disk hotplug supports add and remove. Before hotplugging a Disk it
must be assembled. Use blockdev_assemble RPC, get the device link_name
and then call hotplug RPC command.
In order to remove a disk (with blockdev_remove) it must be shutdown. So
after unplugging the disk ShutdownDiskInstanceDisks() must be invoked.
For both device types we use the generic RPC call_hotplug_device.
Also adapt unit tests to follow the change.

(2.10) Helper methods for PCI slots and device ids
Device naming:
QEMU monitor expects devices to be uniquely named. Device ids derive
from the following function:
kvm_devid = <device_type>-<part of uuid>-pci-<pci_slot>
Device ids must be reproduce-able when we want to remove them.
For that reason we store the pci slot inside the runtime file and
in case we want to remove a device we obtain its pci slot by
parsing the corresponding runtime enrty and matching the device
by its uuid.
Finding the PCI slot:
For newly added devices Hypervisor parses existing PCI allocations
(via _GetFreePCISlot() and eventually ``info pci`` monitor
command) and decides the PCI slot to plug in the device. During
instance startup hypervisor invokes _UpdatePCISlots() for every
device of the instance. Initial PCI reservations derive from KVM
default setup, that allocates 4 slots for devices other than disks
and NICs.

Ganeti.Rpc: use brackets for ipv6 addresses
We detect an IPv6 vs V4 address based on columns, rather than passing
the family from the cluster object to be more future proof (in case
we'll ever support mixed clusters).
Unfortunately quite a bit more code is required to test this: we need an
arbitrary node that does the right thing w.r.t. ip addresses and also
test-only exports. As such we'll do this out of the stable branch.

Fix socket permissions after master-failover
When using gnt-cluster master-failover, on the soon-to-be-master the
luxi daemon is started by the node daemon. This makes the luxi
daemon inherit the node daemon's umask 077, making the communication
socket unreadable to group members. When using Ganeti with non-root
users, this causes problems, as reported in issue 477.
To fix this, the socket permissions are set explicitly.

DRBD: ensure peers are UpToDate for dual-primary
DrbdAttachNet supports both, normal primary/secondary node operation, and
(during live migration) dual-primary operation. When resources are newly
attached, we poll until we find all of them in connected or syncing operation.
Although aggressive, this is enough for primary/secondary operation, because
the primary/secondary role is not changed from within DrbdAttachNet. However,
in the dual-primary ("multimaster") case, both peers are subsequently upgraded
to the primary role. If - for unspecified reasons - both disks are not
UpToDate, then a resync may be triggered after both peers have switched to
primary, causing the resource to disconnect:
kernel: [1465514.164009] block drbd2: I shall become SyncTarget, but I am
primary!
kernel: [1465514.171562] block drbd2: ASSERT( os.conn == C_WF_REPORT_PARAMS )
in /build/linux-rrsxby/linux-3.2.51/drivers/block/drbd/drbd_receiver.c:3245
This seems to be extremely racey and is possibly triggered by some underlying
network issues (e.g. high latency), but it has been observed in the wild. By
logging the DRBD resource state in the old secondary, we managed to see a
resource getting promoted to primary while it was:
WFSyncUUID Secondary/Primary Outdated/UpToDate
We fix this by explicitly waiting for "Connected" cstate and
"UpToDate/UpToDate" disks, as advised in [1]:
"For this purpose and scenario,
you only want to promote once you are Connected UpToDate/UpToDate."
