Support Xen on ARM #97

Open CoderSherlock opened 7 years ago

CoderSherlock commented 7 years ago

I noticed that currently Xen only support running on x86 machines. Is there any way can make bake arm-Xen images which can be run on an arm hypervisor?

There is nothing in principle stopping this.

I think the biggest work item is probably that the rumpkernel project has a forked copy of mini-os, which doesn't support ARM. Upstream mini-os does seem to have some ARM support, although I don't know its status.

If the rumpkernels could be switched to using upstream mini-os (which would necessarily involve sending some changes from rump back upstream) then most of the functionality ought to come out in the wash.

I'm CCing the minios maintainer and also some Xen ARM folks. Hopefully they will correct me if I'm wrong about any of this.

Various stakeholders worked on Mini-OS support for ARM but unfortunately nothing has been made upstream yet.

I am aware that ARM is interested in providing 64-bit ARM support to Mini-OS. I have CCed some ARM people to give more feedback here.

Hi,

Currently, we are investigating the minios support on Xen ARM64 and we have planned to support it in the beginning of Q3.

Thanks Kaly

Any further news on this front?

CoderSherlock commented 6 years ago

No further information about it. As far as I know, upstream Mini-OS has integrated ARM X64 support.
