Disk Actions
Command

Action
qm importdisk <vmid> <image_path> <storage>
Attach disk image to VM
qm set <vmid> -<bus><index> <disk_path>
Assign physical disk to VM (passthrough mode)
qemu-img convert -O <format> <input> <output>

Usage Tips
Use lsblk for a quick overview of all block devices
For detailed partition information, fdisk -l provides comprehensive output
Replace <storage> with your storage name when using pvesm commands
LVM commands (pvs, vgs, lvs) provide more concise output than their display counterparts (pvdisplay, vgdisplay, lvdisplay)
When using du -sh /path, replace /path with the directory you want to check
Replace placeholders like <vmid>, <bus><index>, <disk>, <format>, <input> and <output> with the actual values you intend to use.
