Hi,

We're currently deploying new nodes in our infrastructure and been trying to migrate some instances to these newly added hosts.

We haven't been able to do so due to the instances being deployed with no "processor compatibility" enabled.

We have taken a look at the nova's configuration file and it appears that "limitcpufeatures" is enabled (true).

Do we have to specify additional arguments when deploying the image file to glance in order to enable cpu compatibility when deploying new instances ?

We're running Ocata using RDO. 3x nodes running 2016 datacenter (core) with a failover cluster + S2D enabled

Thanks,

Hello,

No, there's only the config option you've mentioned. The config option has to be set in the compute nodes' nova.conf files in order for it to take effect. Changing its value won't affect any existing instances (you cannot change this while the VM is running), so if you want to change the CPU compatibility for existing VMs, you'll have to do it manually.

The config option is taken into account when the instance is created (spawn, rebuild, shelve/unshelve).

Best regards,

Claudiu Belu
