I want to delete the VM itself not just iso file. under PVE there are some test VM.How is this questions different from your previous question here: https://forum.proxmox.com/threads/should-keep-all-iso-even-after-create-vm.134726/?
That's weird. Please share the output ofit deletes the SDD and drives and crahses other VM's too as it says the referenced disks also gets destroyed.
qm config 101
. DId you create a template? Why would it delete "the SDD and drives and crahses other VM's too"?Why do you think it would delete "the SDD and drives and crahses other VM's too"? The VM has (private) virtual disks which will be removed. If this is (again) about the ISOs: it will not remove those (they are references, not copies or owned).
