Somewhat separately, Alex Agache has already started some preliminary hacking on supporting Xen guests within rust-vmm (on top of Linux/KVM): https://github.com/alexandruag/vmm-reference/commits/xen Being able to run on *actual* Xen would be good too. And we should also aspire to do guest-transparent live migration between the two hosting environments. Where relevant, it would be great to be able to share components (like emulation of the Xen PCI platform device, a completely single-tenant XenStore implementation dedicated to a single guest, perhaps PV netback/blkback and other things).
