Allow guest drivers is fine though I guess? > 2) we should > always do things in userspace unless we absolutely have to do things in > the kernel. Wrong. There are often good reasons to do stuff in kernel, even if you can do it in userspace too. > Adding new kernel drivers breaks support for enterprise Linux distros. > Adding a userspace daemon does not.

Ok, so the virtio-serial + usbserial combo should work well then I think. If you have guest drivers you'll go the virtio-serial route. If you don't have guest drivers you can go the usbserial route, either via /dev/ttyUSB or via libusb. We can also have a libvmchannel as abstraction layer on top of this. cheers, Gerd _______________________________________________ Virtualization mailing list [email protected] https://lists.linux-foundation.org/mailman/listinfo/virtualization
