Hi all, Has anyone seen guest crashes/freezes associated with KVM unhandled rdmsr messages in dmesg on the hypervisor?
We have seen these messages before but never with a strong correlation to guest problems. However over the past couple of weeks this is happening almost daily with consistent correlation for a set of hosts dedicated to a particular HPC workload. So far as I know the workload has not changed, but we have just recently moved the hypervisors to Ubuntu Xenial (though they were already on the Xenial kernel previously) and done minor guest (CentOS7) updates. CPU mode is host-passthrough. Currently trying to figure out if the CPU flags in the guest have changed since the host upgrade... Cheers,
