Description of problem:Already Set a range of MAC addresses(About 8000) for use by using engine-config -s MacPoolRanges ...but when deploy the VM with predefined OS template with 2 Network card attached..upto 893 VM's can be deployed but after that VM failed with "Insufficient amount of free MACs"..

[root@ccr01 ~]# engine-config -g MacPoolRanges
MacPoolRanges: 00:1A:4A:FA:F1:00-00:1A:4A:FA:F1:FC,00:1A:4A:FB:F2:00-00:1A:4A:FB:F2:FC,00:1A:4A:FC:F3:00-00:1A:4A:FC:F3:FC,00:1A:4A:FD:F4:00-00:1A:4A:FD:F4:FC,00:1A:4A:FE:F5:00-00:1A:4A:FE:F5:FC,00:1A:4A:FF:F6:00-00:1A:4A:FF:F6:FC,00:1A:4A:EA:F7:00-00:1A:4A:EA:F7:FC,00:1A:4A:EB:F8:00-00:1A:4A:EB:F8:FC,00:1A:4A:97:5A:00-00:1A:4A:97:5A:FD,00:1A:4A:97:5B:00-00:1A:4A:97:5B:FE,00:1A:4A:97:5C:00-00:1A:4A:97:5C:FE,00:1A:4A:97:5D:00-00:1A:4A:97:5D:FE,00:1A:4A:97:6A:00-00:1A:4A:97:6A:FE,00:1A:4A:97:6B:00-00:1A:4A:97:6B:FE,00:1A:4A:97:6C:00-00:1A:4A:97:6C:FE,00:1A:4A:97:6D:00-00:1A:4A:97:6D:FD version: general

Inside the Engine the free mac address :-

-bash-4.2$ psql -h localhost -U engine -d engine
Password for user engine:
psql (9.2.7)
Type "help" for help.
     
engine=> select count(*) from vm_interface where mac_addr is not NULL;

Upto 893 VM can be deployed with the same OS templates but after 893 can not be deployed with 2 Network card... 


Version-Release number of selected component (if applicable): 3.5.1.1-1.el7 


How reproducible:100%


Steps to Reproduce:

1. Create one VM with two Network card attached..once all done...make an template with it..
2. Set MAC Pool Range to a known(like 4000 mac address) range using engine-config (and restart ovirt-engine service)
3. Attempt to create 893 VM from this mac address pool range..
4. 894th VM will fail with the error "Insufficient amount of free MACs" 

Actual results:-VM failed to create through OS template with error "Insufficient amount of free MACs"..actually there are lots of Macs are free..

Expected results:- Should allow 2 NICs to be created with auto-assigned MACs..

Additional Info :- The VM can be create either i will remove both the network card from the template or remove one network card from template...
