[ovirt-users] No MAC addresses left in the MAC Address Pool

2015-11-06 Thread nicolas 

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

null, Custom Event ID: -1, Message: No MAC addresses left in the MAC 
Address Pool.

for user XXX@YYY. Reasons: 
VAR__ACTION__ADD,VAR__TYPE__VM,MAC_POOL_NOT_ENOUGH_MAC_ADDRESSES


Is there a way to increase the MAC Pool?

Thanks.

There are 2 settings to play here:

# engine-config -g MaxMacsCountInPool
MaxMacsCountInPool: 10 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.
