Oh, I didn't that It's almost what we are doing currently ?

pve.volid : storeid:volname
lxc.rootfs: loop:/var/lib/vz/images/128/vm-128-rootfs.raw



So, it coud be easy to extend it to manage multiple disk

pve.volid1 : storeid:volname:/
lxc.rootfs: loop:/var/lib/vz/images/128/vm-128-rootfs.raw

pve.volid2 : storeid:volname:/home
lxc.mount.entry: /home ....

>>do we really need to have rootfs or ext4fs in filename ? 

for example : lxc.rootfs = .../100/vm-100-rootfs.raw 


if not, why not something generic like ct-$vmid-$i.raw ? 

(ct for container, vm for vms) 

lxc.rootfs = .../100/ct-100-1.raw 





Also, 
I see that currently we put loop,nbd in config with path 

lxc.rootfs = loop:/var/lib/vz/images/100/ct-100-1.raw 

I think we should do like in qemu 

lxc.rootfs = storeid:100/ct-100-1.raw 
Then generate the path , activate_volumes with mounting loop,rbd at ct start. 


I think we can't use this syntax directly because lxc_start need full path for lxc.rootfs or lxc.mount.entry ? 

Maybe can we use 
pve.volid1 = storeid:mountpoint 
pve.volid2 = storeid:mountpoint 
pve.volid3 = storeid:mountpoint 

to store config, 
the at vm_start, update lxc.rootfs && lxc.mount.entry ?

I would like have different names for kvm and lxc images: 

vm-$vmid-rootfs-$i.raw 

or 

vm-$vmid-ext4fs-$i.raw 

or 

vm-$vmid-lxc-$i.raw 

?
