This thread explains where to find special devices that correspond to ZFS disk image in Proxmox:

whether or not virt-customize can handle such paths, I dont know. Try it.

Can't get that to work.
My issue is I have a ZFS virtual machine that has no network interfaces I need to install netplan how would I go about doing that on ZFS? Maybe @Dunuin can save me again
If it wasn't ZFS normally I would just shutdown the VM and run
Maybe I can chroot in?

I dont know what exactly you cant get to work, but in theory you can convert the ZFS based disk to qcow or raw, edit it and then convert back.

Something like qm guest exec can work if the VM is running? But the QEMU Guest Agent needs to be installed first.
That would require the network on the VM to be working though.
The solution was
Code:
mkdir -p /mnt/100
mount /dev/zvol/zfs/vm-100-disk-0-part2 /mnt/100Then chroot in
Code:
chroot /mnt/100and finally run commands
Code:
apt install netplan -yNo, it does not. You only need access to the Proxmox node and QEMU GA needs to be running inside the VM. But glad you got it working anyway.
By the way...
Still the question if it would have helped. I guess a guest without a network interface also can't use apt to install packages without a internet connection.
You can copy the contents of the package (or an archive of multiple ones) via stdin, or use virtio-fs or 9p to provide a file share. I guess there is little you can't do via a virtual PCI(e) device... ;-)
@harmonyp You almost had it, just use the raw
zvol:
Bash:
$ virt-customize -a /dev/zvol/zfs/vm-104-disk-0 --install netplan
[ 0.0] Examining the guest ...
[ 2.1] Setting a random seed
virt-customize: warning: random seed could not be set for this type of
guest
[ 2.1] Setting the machine ID in /etc/machine-id
[ 2.1] Installing packages: netplan
[ 9.1] Finishing off
# You may want to reset the machine-id afterwards
$ virt-customize -a /dev/zvol/zfs/vm-104-disk-0 --run-command "echo -n > /etc/machine-id"
