Sure, not a problem at all, also because for this year QEMU was not accepted in GSoC, so anybody can work on those projects if they have time > I have gone through QEMU's list of GSoC '24 projects [1] and am > interested in two of them: > > 1.

While vhost-user memory isolation is not really related to migration, but both are related to virtio devices.
