So,you have edited the vm conf file manually ?

But you are not allowed to choose a name (gui or qm create), as proxmox create itself the disks with vm-<vmid>-disk-<diskid>


in RBDPlugin.pm
->rbd_ls()

 if ($line =~  m/^((vm|base)-(\d+)-disk-\d+)\s+(\d+)(M|G|T)\s((\S+)\/((vm|base)-\d+-\S+@\S+))?/) {

also

>parse_volname()
  if ($volname =~ m/^((base-(\d+)-\S+)\/)?((base)?(vm)?-(\d+)-\S+)$/) {



If you have edited manually the vm config file with custom name, I think qemu can start, 
but I'm not sure of the behaviour of proxmox when you add/remove/resize,... disk if the name is wrong.

This template has no disk. And the Name base- was chosen by me while 
creating the VM. I didn't know that i'm not allowed to choose this name 
for a normal VM. Bug?
