[ovirt-users] kernel parameter "spectre_v2=retpoline"

Hi, I'm planning to upgrade my installation from CentOS 7.6/oVirt 4.3.5 to CentOS 7.7/oVirt 4.3.7. According to https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/htm... there's a new default setting for Spectre V2 mitigation in new RHEL 7 installs. Shall I switch my hypervisor hosts to this setting when upgrading? Would newly installed CentOS 7 oVirt hosts have that kernel parameter? thx Matthias
