[sorry= for the possible format issues]

I am sorry to jum= p into the conversation too late.

Sorry for the late reply.

> What do we need in order to move on on this?

The next steps would be
=C2=A0 1) Write a PoC to confirm the approach is feasible
=C2=A0 2) Write a design document

Unfortunately, I will not have time to work on it any time soon. Is it
something you plan to work on?

I am wor= king on this PoC on Xen on Arm right now taking into the account the detail= s that we initially discussed on the IRC, unfortunately,=C2=A0I had to post= pone this activity several times due to the limited bandwidth,
bu= t this time, I hope, I will be able to finish this PoC without interruption= ) I will try to share Xen+Linux changes in a week, so we will able to discu= ss them.=C2=A0=C2=A0
