Hi, colleagues, just would like to share that yesterday successfuly upgraded my ubuntu 14.04 kvm cloud to custom built linux 4.14.11 keenel with ubuntu 2018/01/08 intel cpu microcode update. Compute CPUs - Xeon E5-2670, Xeon X5650, everything works nice, no claims from customers, no sensitive load change. Live migration between new and old kernels goes well, back migration too. It seems that kvm, libvirt and qemu patches are not here yet for Ubuntu. Waiting for additional updates. Btw, It is CS4.3.
Have a nice migration.
