Package: qemu-system-xen
Version: 1:7.2+dfsg-7+deb12u1
Dear Maintainer,
The Xen build of Qemu lacks 9pfs support, which results in guests unable
to mount 9pfs shares defined in the domU configuration file.
This kind of setup was working correctly in bullseye, before the
binaries were split.
The failure is silent on the host side. Qemu does not error out and Xen
starts the domU as if the 9pfs backend was set up successfully.
Inside the guest, the kernel spits out an error after a 270 seconds
delay (see attachment).
The solution is to compile qemu-system-xen with --enable-virtfs
This option also requires --enable-attr --enable-cap-ng
