[pve-devel] UUID for VM's and disks

[Andrew Thrift]

Hi,

Have the Promox VE team thought about using UUID's for VM's as well as
for Disks ?

The use of VMID's for disks is becoming an issue for us with Ceph.  We
cannot have multiple PVE clusters sharing the same pool on Ceph as
there will be duplicate VMID's across the clusters that will result in
a clash of RBD names on Ceph.  I am sure this would be an issue with
iSCSI+ZFS as well.

Using UUID's for VM's would have benefits when using an external
application to manage multiple PVE clusters.

VMID's could be retained for ease of management when using the local
PVE web management, but via the API and internally UUID's could be
used.


Regards,



Andrew
