This morning I noticed the message about updates availalble for my CentOS 7.3 host. A yum update on it proposed qemu-kvm-ev 2.6.0-28.el7_3.3.1 and related packages The changelog from the current one (2.6.0-27.1.el7) seems quit big (see below)... I applied it and I'm going to test. After working on the first host and activatinh inside the cluster, do you think I can live migrate a VM from a 2.6.0-27.1.el7 host to a 2.6.0-28.el7_3.3.1 in your opinion?
