Intel meltdown/spectre kvm upgrade results
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.

Hi, I don't see spontaneous reboots yet, but have heard that some people
met them with new intel ucode.

Thx Ivan for sharing, no reboot issues because of problematic Intel
microcode ?
This is just Meltdown fix for now, and btw congrats on courage to do so
this early (since no final solution yet).
FYI, CentOS/RHEL has already patched everyhing (kernel and qemu/libvirt)
but we are also on Ubuntu..
Cheers

Good!
Thanks for sharing it, nice iniciative!
We have to upgrade the VMware clusters, but vmware is changing daily the
patch policy...
Once done I will try to remember to share too.
Regards.
Atentamente,
