list which iso or template is used/required for vm/ct?

[rcd]

Is there a way to list which iso or template is used/required for vm/ct?

I am carefully taking snapshots but just realize (sometime?) the iso/template used to create it is required in order to restore it. I realize I perhaps should have made a note of it during creation, but I didn't.

I'm sure there must be a way to show it by vmid/ctid or something?

Yes, just use grep:

root@proxmox7 ~ > grep -ri cdrom /etc/pve/nodes/*/qemu-server/ | grep -v none
/etc/pve/nodes/proxmox6/qemu-server/5011.conf:ide2: iso-generator:iso/RHEL_8.7.0_2023-05-08_16-18-23-c182654_x86_64.iso,media=cdrom
/etc/pve/nodes/proxmox6/qemu-server/7098.conf:ide2: local:iso/SNG7-PBX16-64bit-2208-2.iso,media=cdrom,size=2377M
/etc/pve/nodes/proxmox7/qemu-server/2008.conf:ide2: isodump-linux-generell:iso/ipxe.iso,media=cdrom,size=700K
/etc/pve/nodes/proxmox7/qemu-server/2008.conf:ide2: isodump-linux-generell:iso/ipxe.iso,media=cdrom,size=700K
/etc/pve/nodes/proxmox7/qemu-server/5203.conf:ide0: iso-generator:iso/OL_6.9_2017-12-12_15-31-15-49632d2_x86_64.iso,media=cdrom,size=3999884K

You can also edit a snapshot with your favorite editor and change the cdrom manually. Snapshots of the configuration are not frozen and can be edited.

Isn't this just the currenly mounted isos? What if they have been unmounted/ejected, would they still show?

What about containers, they don't need the base iso to restore?

I'm not sure if I understand you correctly, but a restore of a container does not need the original template (it's all in the backup).

EDIT: I'm sorry, I don't understand "base iso". Maybe I should not have tried to answer the question.

 

[rcd]

I've been in the situation of moving a snapshot from one server to another, and got the error that the base iso was missing. I don't recall if it was VM or CT, hence the question.

Yu can move disks around, but not snapshots. What did you do exactly?

Not only currently, also all snapshots, because a snapshot is also a copy of the plain config settings.

What if they have been unmounted/ejected, would they still show?

No, they are set to none.
