It would help to know which operation is not supported.
Could you get the coredump?
Is it possible to run the operation with "QEMU_STRACE" set in the environment?
Normally loop ioctls are supported.
But it seems the following ones are not implemented in QEMU:
LOOP_SET_CAPACITY, LOOP_SET_DIRECT_IO, LOOP_SET_BLOCK_SIZE.

Title:
systemd complains Failed to enqueue loopback interface start request:
Operation not supported

Unknown
Bug description:
This symptom seems similar to
https://bugs.launchpad.net/qemu/+bug/1823790
Host Linux: Debian 11 Bullseye (testing) on x84-64 architecture
qemu version: latest git of git commit hash
eb2c66b10efd2b914b56b20ae90655914310c925

Bug report (closed) to systemd:
https://github.com/systemd/systemd/issues/16359
systemd in armhf and armel (both little endian 32-bit) containers fail to
start with
Failed to enqueue loopback interface start request: Operation not supported
How to reproduce on Debian (and probably Ubuntu):
mmdebstrap --components="main contrib non-free" --architectures=armhf
--variant=important bullseye /var/lib/machines/armhf-bullseye
systemd-nspawn -D /var/lib/machines/armhf-bullseye -b
When "armhf" architecture is replaced with "mips" (32-bit big endian) or
"ppc64"
(64-bit big endian), the container starts up fine.
The same symptom is also observed with "powerpc" (32-bit big endian)
architecture.
