Subject: Half a usb-redir idea
Date: Tue, 16 Mar 2021 17:21:02 +0000 [thread overview]
Message-ID: <YFDo/oHikOEcXFcg@work-vm> (raw)
Hi,
I've got a half-baked idea, which I thought might be worth mentioning.
How hard would it be to give qemu a usbredir server rather than client?
It would have nothing guest visible but would look logically like the
front (?) half of a usb interface; then you could use all of the
existing qemu emulated and passthrough device code, to build a usb
hierarchy and present it to a remote qemu.
You'd get the ability to do emulated USB CDROM/storage, audio, network
and the glue for host USB connection (and smart cards??) - all in one
client that you can then use for connecting to a remote qemu.
The next step of that is to make something analogous to a
qemu-storage-daemon, but for USB, so you have something that can
do all that USB stuff without actually having any processors.
The even crazier step would then be to add a VNC client, and then you
have an almost complete remote client.
Dave
