@rzr but why.... what example use case would this be useful in?
-
Ah nice! I did a similar test few years ago on a similar CPU, but with twice or 4 times the RAM

At least (stress) testing purposes...
It could make sense for edge computing eventually... or DiY "battery operated solar powered portable environments"

There's many use cases, and VMs are great for isolation but also capabilities to monitor with a central XOA, restore/backup and much more.
-
Unikraft would a a good fit for ram-constained devices.
Being able to have useful VMs with 32-64 MB each. -
I wonder to which extend we could lower dom0 memory, eventually reduce the set of features for this kind of usecases.
I can definitely see a pool of machines (x86 or ARM) for industrial purpose where that could make sense, and that could be managed and update through XOA. -

As such I think that the handling of this should be an install time choice, as changing an already existing host to a MicroVM capable one can be messy. Doing it this way will enable a lot of capabilities for use with Xen Orchestra, in the handling of such MicroVMs.
A hyperscaler already has this technology (Amazon AWS) with their Firecracker software technology.

HP T740 with 64g of ram, 256g sata for OS, optional nvme for faster storage, optional 10gbe networking through low profile card. Works great for my lab.
Ran vSphere8 on three of them, running Harvester on 3 of them now. XCP-ng and vSphere8 work great, Harvester is a bit more resource hungry. Only the bottom three have nvme and currently have Harvester 1.7.0 running while I try to find time to learn more about this system.

Nice "little" machines!

I wish I had newer generations of the big HP DL360 on the bottom, mine do not support uefi, and that's getting in the way. Sitting power off to keep the bios battery from running down. Those are 20 cores with 128gb each, and again 10gbe networking.
