[20.04 FEAT] zKVM: Crypto Passthrough Interrupt Support - qemu part

[bugproxy]

Enhance the implementation of Crypto Passthrough for KVM with interrupt support to achieve improved performance and CPU utilization

Available with qemu 4.1

[Frank Heimes (fheimes)]

Changing for now to Incomplete until qemu-kvm 4.1 became available.

[Christian Ehrhardt  (paelzer)]

did this get into qemu 4.1 or at least 4.2 as planned?
Can we call this done once 4.2 is available in Ubuntu or cherry pick this from git - otherwise do you want to punt this to 20.10?
