There is no overlay on ext4-based virtual routers. # mount|grep ext4 /dev/mapper/pve-vm--501--disk--0 on / type ext4 (rw,relatime,stripe=512) The /overlay directory exists just like the /rom one does but they're empty: # ls -l /|grep -E 'overlay|rom' drwxr-xr-x 2 root root 1024 Jan 27 23:53 overlay drwxr-xr-x 2 root root 1024 Jan 27 23:53 rom These are empty directories (there is a note file in /rom with some info for those using squashfs which is not applicable to these installations).
