KVM: strip boot=on from IDE CDROM drivers

boot=on forces KVM to use an extboot ROM which has shown poor behaviour with
booting from CD images. IDE CDROM emulation (which is forced by default when
booting from CD) does not need boot=on, so we simply omit it....

KVM: configure bridged NICs at migration start

Commit 5d9bfd870 moved tap interface handling from KVM to Ganeti, partly to
also solve the problem of routed interfaces getting configured too early during
live migrations, causing network anomalies. In that direction, configuration of...

Remove duplicate CDROM_IMAGE_PATH KVM hv param def

Introduced during merge, because of fba7f91. Remove the second definition, as
it broke KVM HTTP CDROM boot.

New Parameters:
- floppy_image_path = "" -> Specify the floppy image to load as
floppy disk.

Make root_path an optional hypervisor parameter

This will allow us an easy migration to pv-grub, because a set root_path
confused pv-grub.

kvm: check that the ISO image is there if it's a URL

Perform a simple urllib2 check on ISO images specified as URL before instance
start, so as to work around qemu bug #597575 [1].

KVM: use cache=none for shared disk templates

Disable host cache for externally mirrored disks to avoid cache incoherency.
Without this, migrations between the same two nodes may end up in disk
corruption.

This is a runtime override of cluster defaults, mostly a workaround....

Allow KVM to boot from HTTP

New versions of KVM support booting from HTTP-hosted ISO
images, via libcurl. This patch adds a proper check to
allow defining either a sane, absolute path or an HTTP
URL as an iso image path.

Remove "format=raw" from the cdrom device options when iso_image...
