After a reboot, my VMs came up with my virtiofs mounts successfully mounted.
As a side note, the updated/fixed qemu-system-data didn't install automatically when selecting qemu-system-x86 whereas all of the other dependencies did. Looking at the dependencies of qemu-system-x86, most of them are pinned to a matching version but qemu-system-data is a ">>".
Just to add a +1 that the packages in jammy-proposed fixed the issue for me. I installed:
qemu-block-extra 1:6.2+dfsg- 2ubuntu6. 14 2ubuntu6. 14 2ubuntu6. 14 2ubuntu6. 14 2ubuntu6. 14 2ubuntu6. 14
qemu-system-common 1:6.2+dfsg-
qemu-system-data 1:6.2+dfsg-
qemu-system-gui 1:6.2+dfsg-
qemu-system-x86 1:6.2+dfsg-
qemu-utils 1:6.2+dfsg-
