Hi,
I wonder if this addition of qemu-storage-daemon with fuse would be
able to solve the following issue I just opened:
https://bugzilla.proxmox.com/show_bug.cgi?id=6953
"cannot set set-require-min-compat-client to reef, luminous clients
from kernel rbd due to VM with TPM /dev/rbd"
The rbd kernel module feature is stuck to luminous and swtpm use of
kernel /dev/rbd limits the usable features of the whole proxmox/ceph
cluster as soon as a VM with TPM is created on the cluster.
If possible using qemu-storage-daemon to export the rbd image to swtpm
would still allow proxmox to leave the TPM disk on ceph while
benefiting from recent ceph features.
Sincerely,
Laurent GUERBY
PS: ZFS over iSCSI isn't usable for TPM as well

TPM disfunctional with ZFS over iSCSI
