Add a node powercycle command

This (somewhat big) patch adds support for remotely rebooting the nodes
via whatever support the hypervisor has for such a concept.

For KVM/fake (and containers in the future) this just uses sysrq plus a
‘reboot’ call if the sysrq method failed. For Xen, it first tries the...

Move to data-based hvparam checks instead of code

Currently the hypervisor parameters are checked using hard-coded snippets in

Move more hypervisor strings into constants

This patch adds constants for the mouse and boot order strings; while
there are still some issues remaining, we're trying to cleanup hardcoded
strings from the hypervisors.

Since the formatting of frozensets is currently wrong, we also add an...

Move HVM's device_model to a hypervisor parameter

This moves yet another hardcoded value to a hypervisor parameter. I
removed the 64/32 difference as it doesn't seem valid to me - it's more
of a local site config rather than arch config.

Fix xen-hvm and KERNEL_ARGS

xen-hvm doesn't have KERNEL_ARGS, and I just changed blindly all old

Remove the extra_args parameter in instance start

This patch removes the extra_args parameter and instead switches the

This is a big change, but it's a needed cleanup, this extra parameter on

Simplify a little the hypervisor routines

Instead of “instance.hvparams”, we use a shorter “hvp” name to make readability

GetShellCommand: get hvparams and beparams
