- KVM < 1.0
 - existing devices in the cluster
 - python-fdsend module is not installed (NIC hotplug)
 - chroot (Disk hotplug)
 - security mode other than None (Disk hotplug)...

Hepler 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....

Prepare block_devices runtime entry

With this patch we add another entry in runtime files along with
kvm_cmd, kvm_nics, and hvparams. block_devices that used to be
encapsulated inside kvm_cmd, live now separately just like nics do
but in tupples of (L{objects.Disk}, dev_path)....

Prepare kvm options to support -device for disks

Newer kvm version support -device driver,... option where available
drivers can be found by running kvm -device ? command. Currently
ganeti uses `if` property of driver to define the disk type to use
which is also passed as hvparam. This patch prepares the use of...

block_devices = (disk, link, uri)

Do not pass BlockDev instance to hypervisor. Instead calculate the
drive_uri (if any) in backend level and pass only the string to
hypervisor.

Hypervisor should not be aware of the entire block device but only
the final path it can be reached....

Hardcode default access mode to kernelspace

Hardcode constants.KERNELSPACE as the default access method for
KVM disk templates, rather than allowing a change to the RBD default
access mode to affect all disk templates for KVM.

At some point in the future it might make more sense to have this...

Handle scenarios where access is not set

It should not be possible to reach _GenerateKVMRuntime without having
the access method set, but if it does happen this commit makes sure
the default value is used anyway.
