[pve-devel] [PATCH cluster/guest-common/qemu-server v5] virtio-fs

Dominik's "schema/config array support" patch-series is required.

I did get numa to run with virtiofs. I just needed to replace
memory-backend-ram with memory-backend-file on mem-path=/dev/shm. However I did
not find a way to use hugepages with virtiofs.

I will send the other patches for api, access-control, check_local_resources,
doc and so on, when Dominik's patches for cluster mapping are applied.

 * allow numa settings with virtio-fs
 * added direct-io & cache settings
 * changed to rust implementation of virtiofsd
 * made double fork and closed all file descriptor so that the lockfile
 gets released.

 * created own socket and get file descriptor for virtiofsd
 so there is no race between starting virtiofsd & qemu
 * added TODO to replace virtiofsd with rust implementation in bookworm
 (I packaged the rust implementation for bookworm & the C implementation
 in qemu will be removed in qemu 8.0)

 * replaced sharedfiles_fmt path in qemu-server with dirid:
 * user can use the dirid to specify the directory without requiring root access
