[SOLVED] Zentyal 2.2 error creating hard disk for VM

[acon]

I am testing 2.2 to migrate my server.
In test machine, i have created a VM but when i add the virtual disk, when i save changes i get tis error:
"element no existente: mac"
In /var/log/zentyal/zentyal.log i get:
2011/11/01 08:16:16 DEBUG> Row.pm:409 EBox::Model::Row::elementByName - element no existente: mac.
Iny idea?

Thanks

May be something related to upper case in HD or VM names?
Deleted the VM and created a new one with lower case names and everithing works as expected.
