Hi,
as you probably noticed, CentOS 7.3 is rolling out right now and will be announced pretty soon.
Please note that due to new libvirt shipped within CentOS 7.3, it is required to update qemu-kvm-ev to 2.6 at the same time.

If you're using CentOS Virt SIG rpms / repos for oVirt this should happen automatically. 
If you're using only ovirt repositories be sure to have qemu-kvm-ev 2.6 if you update to CentOS 7.3.

In terms of ovirt repositories, qemu-kvm-ev 2.6 is available right now in ovirt-master-snapshot-static, ovirt-4.0-snapshot-static, and ovirt-4.0-pre (contains 4.0.6 RC4 rpms going to be announced in a few minutes.)

Thanks,

Hello,
where to find details about this info?
I ask because on my tests in a nested environment with 4.1 beta on CentOS 7.2 + CR (that should match upcoming 7.3) I was not able to power on the SHE VM using qemu-kvm-ev-2.6.0-27.1.el7.x86_64.rpm manually downloaded by http://buildlogs.centos.org/centos/7/virt/x86_64/kvm-common 

Got error
warning: host doesn't support requested feature: CPUID.07H:EBX.erms [bit 9]

While I was able to install and run self hosted engine using the provided qemu-kvm-ev-2.3.0-31.el7_2.21.1.x86_64 (not tested yet powering on a "normal" VM)

Currently on this server
