IMPORTANT NOTE: this series should be applied on top of my previous series "Introduce a shared base for application VMs" [1]. This is a bit inconvenient I know, but I haven't committed the other series yet due to wanting to take a second pass at it. This series adds the Spectrum-side support for running VMs that can display Wayland windows on the host compositor, using virtio-gpu. There are various small things still to be resolved, but it's ready for other people to try out and test. The easiest way to test this out is to run "vm-start hello-wayland" on the Spectrum host. If everything goes well, a small window with a picture of a cat (hello-wayland) should appear. This window is running in a VM. One particular known issue is that on one run of the new appvm-hello-wayland, I got this error: [12:11:52.107] libwayland: error in client communication (pid 863) I'm not yet aware of what would cause such an error. It went away after I rebooted and tried again. There are some other known issues with my cloud-hypervisor patch too. See the other thread for information on those.
