Re: [MirageOS-devel] Possible to build for Xen HVM?

[Andrew Stuart <andrew.stuart@xxxxxxxxxxxxxxxxxx>]

Hi Anil,

Iâd like to execute the unikernel on KVM or Xen HVM or EC2 HVM, all of which I 
understand to be compatible.

The direction at EC2 is HVM rather than PV and the new instance types are all 
HVM.

Various other cloud providers are KVM so it would be good to be able to execute 
on such targets.

Iâm familiar wih rumprun so maybe thatâs the right way to go for KVM/HVM 
functionality. I was wondering if MirageOS unikernels were able to do 
standalone HVM without needing rump.

PVâs need for a specific kernel is less flexible than HVM/KVM


thanks
