[Users] DL380 G5 - Fails to Activate

[Tom Brown]

Hi

I have a couple of old DL380 G5's and i am putting them into their own cluster for testing various things out.
The install of 3.1 from dreyou goes fine onto them but when they try to activate i get the following

Host xxx.xxx.net.uk moved to Non-Operational state as host does not meet the cluster's minimum CPU level. Missing CPU features : model_Conroe, nx

KVM appears to run just fine on these host and their cpu's are

Intel(R) Xeon(R) CPU            5140  @ 2.33GHz

Is it possible to add these in to a 3.1 cluster ??

thanks
