Looks good, but I am not to much familiar with p9. Will it provide us
with stream semantics?
Sure. It has read and write operations. You just have to implement
them in the same sort of way you'd implement them for a character device.
How much work is needed to support this in
Windows (what is your estimation)?
If you structure your guest applications to use a library, sort of like
libsysfs, then on Windows, you could implement a 9P client in
userspace. I have a 9P client that can be used for this. You just need
some way to get the stream to userspace. You could write a virtio
windows driver that exposed the stream down to userspace. You could
also use an alternative transport for Windows (like a serial port).
Will migration be transparent to
in guest users?
There's no better migration story for vmchannel backends implemented
outside of QEMU. For the ones in QEMU, migration should be transparent.
