I think you should be able specify this within the ovirt-engine, just modify the cluster's cpu compatibility. I hit this too, but i think I just ended up provisioning the older machine first then the newer ones joined with the older model On Thu, Jul 17, 2014 at 11:05 PM, George Machitidze <gmachitidze@greennet.ge> wrote:

1. first the host needs to have a compatible cpu model. what does 'vdsClient -s 0 getVdsCaps | grep -i flag' returns 2. cluster cpu level is easy, but hosted engine vm config resides on the disk, and needs to be manually edited in this case iirc.

Than can you also check the presence of vmx and nx flags in /proc/cpuinfo ? Recently we solved a bug regarding that: https://bugzilla.redhat.com/show_bug.cgi?id=1119145 Hosted engine deploy didn't checked the status of nx flag but some CPU requires also to enable NX to properly support virtualization.
2. cluster cpu level is easy, but hosted engine vm config resides on the disk, and needs to be manually edited in this case iirc.

Simone, Itamar thanks for reply nx flag doesn't exist on second host. should it throw this partucular error and not detect cpu type? What is target release for patch? I will build one more test lab for ovirt. I've already faced about 10 bugs in 3.4.2, but all are already solved in 3.4.3 :) *George Machitidze* 2014-07-22 13:37 GMT+04:00 Itamar Heim <iheim@redhat.com>:

Simone, Itamar
thanks for reply
nx flag doesn't exist on second host. should it throw this partucular error and not detect cpu type?
Yes, on some CPUs if the NX flag is not active host-deploy cannot detect the CPU type due to hardware constraints getting that error.
What is target release for patch?
3.5.0 beta2, but the patch is of course not able to enable nx flag by itself: it simply inform the user about that asking him to enable NX support in the bios. https://bugzilla.redhat.com/show_bug.cgi?id=1103672
I will build one more test lab for ovirt. I've already faced about 10 bugs in 3.4.2, but all are already solved in 3.4.3 :)
