Hi,
We're running oVirt 3.5.3.1-1. One of our users is trying to create a
new VM. However, he gets the following warning:
2015-11-05 17:33:12,596 WARN

Is there a way to increase the MAC Pool?
There are 2 settings to play here:
# engine-config -g MaxMacsCountInPool
MaxMacsCountInPool: 100000 version: general
# engine-config -g MacPoolRanges
MacPoolRanges: 00:1a:4a:ab:64:00-00:1a:4a:ab:64:ff version: general
You're probably exhausting the MacPoolRanges. You can either extend the
current range or add a new range, using commas between the ranges:
# engine-config -s
"MacPoolRanges=00:1a:4a:ab:64:00-00:1a:4a:ab:64:ff,00:1A:4A:97:5F:00-00:1A:4A:97:5F:FF"
Then restart ovirt-engine service.
Iirc, this setting is changing to the UI in ovirt 3.6.
Thanks.
