Converting Xen VM to KVM

In recent days, it's become clear that LimeTech plan to support only KVM virtualisation in unRAID 6 (as well as Docker). When they started out with version 6, Xen was the only virtualisation available and that's the one I went with.

I've been anxious about the learning curve required to migrate to KVM but since Xen is likely to disappear sooner rather than later, I figured it was time to bite the bullet.

LimeTech have published a 'how to' guide on migrating a Win7 VM from Xen to KVM so I decided to record myself following it;

Overall, it's a breeze with just a couple of small hiccups, one relating to not being clear on how to set up KVM support in unRAID and the other not figuring out how to ad an additional virtual disk in the UI. Apart from that, all good - though the new VM UI doesn't seem to support all PCI/PCIe devices for passthrough so I need to figure out how to do that now...
