setup vmid 108 (example):
qm set 108 --hookscript local:snippets/virtiofs_hook.pl
qm start 108
systemctl status virtiofsd-108-media@108
in VM:
mkdir -p /media
mount -t virtiofs 108-media /media
in fstab:
108-media /media virtiofs nofail 0 2
Similar to how LXC bindmounts do mapping of uid from 100000 (on Proxmox host) to 0 (on VM_, we try to have mapping uid and gid, modify the systemd service.
Modify:
/etc/systemd/system/[email protected]
at the ExecStart line, append:
--uid-map :0:100000:65536: --gid-map :0:100000:65536:
then
systemctl daemon-reload
systemctl restart virtiofsd-108-media@108
but journalctl -u virtiofsd-108-media@108 shows:
