any ballpark comparison with rust-vmm ?
-
-
-
rust-vmm is not a VMM per se. But if we compare it with Firecracker, on the guest side, using microvm, differences are minimal. On the host side, FC has a smaller TCB and is written in Rust, while QEMU provides more features and, even if written in C, has a nice security record.

@slpnix Hi, looks very interesting. Could you please share since which qemu version this machine type is supported? -
It'll be included in the next version, 4.2.

Great work! Do we have a plan to support PCI devices, hot-plug, and live migration?
-
We don't have plans to add support for PCI, ACPI nor live migration to microvm. For that kind of workloads, Q35 is better suited. An arch-independent hot-plug implementation would be interesting, but it's probably going to take some time. A mid-term project, maybe.

Nice! Is it x86_64 only for now, or does it work on arm64?
-
It's x86_64 only. AFAIK, the "virt" machine type for aarch64 is quite clean as it is. I'm not sure if there's much room for improvement there.
