[ovirt-users] Is there a way hot to reserve MAC address ?

Hey Guys, is there a way how to reserve MAC address for VMs created from the pool ? I have a workaround via ansible playbook which works fine but I am wondering if there is any other solution how to achieve this. And btw if i use predefined instance type other than Custom there are no network interfaces in newly created machines. Is it right behavior ? Thank you so much !! Cheers -m
