Open Stack

Hi everyone,

I’d like to propose the following driver feature parity blueprint spec for an expection:

https://review.openstack.org/#/c/105042

This blueprint introduces rescue instance support in the Nova Hyper-V
driver for feature parity with other drivers.

The Hyper-V Nova driver is currently not supporting Nova "rescue" commands,
unlike other hypervisor drivers (e.g. libvirt).

The driver can be extended to support the "rescue" feature,
supporting both Linux and Windows images.

Hyper-V uses VHD/VHDX images, not AMI/AKI/ARI. The Nova rescue command will
result in a new temporary image spawned using the same image as the instance to
be rescued, attaching the root disk of the original image as secondary local
disk.

The "unrescue" command will result in the temporary instance being deleted and
the original instance restarted.

Thanks,

Alessandro
