Hi All, Trying to add a nic to a vm with a specific mac address. [oVirt shell (connected)]# add nic --vm-identifier ov31 --network-name backend --name eth4 --mac-address HH:HH:EE:HH:HH:01 ======== ERROR ============================= status: 400 reason: Bad Request detail: MAC address must be in format "HH:HH:HH:HH:HH:HH" where H is a hexadecimal character (either a digit or A-F, case is insignificant). ============================================= Also interesting is when I change the beginning of the mac address to 00 instead of HH, I get : [oVirt shell (connected)]# add nic --vm-identifier ov31 --network-name backend --name eth4 --mac-address 01:HH:EE:HH:HH:01 ============================================ ERROR ========================================== wrong number of arguments, try 'help add' for help. ============================================================================================= I have tried some things like enclosing in single and double quotes but no success. I have also tried to read the help sections on the shell interface but I also could not figure it out. Thanks in advance,
