Hello, Do you know what this means : kvm: 2918: cpu0 unhandled rdmsr: 0x345 kvm: 2918: cpu0 unhandled rdmsr: 0x1c9 kvm: 2918: cpu0 unhandled rdmsr: 0x1a6 kvm: 2918: cpu0 unhandled rdmsr: 0x1a7 kvm: 2918: cpu0 unhandled rdmsr: 0x3f6 tap110i0: no IPv6 routers present kvm: 2952: cpu0 unhandled rdmsr: 0x345 kvm: 2952: cpu0 unhandled rdmsr: 0x1c9 kvm: 2952: cpu0 unhandled rdmsr: 0x1a6 kvm: 2952: cpu0 unhandled rdmsr: 0x1a7 kvm: 2952: cpu0 unhandled rdmsr: 0x3f6 I think it causes instability, we had to reboot the server twice and a backup script still fails.

These messages show that the guest has been doing reads on various MSRs that KVM does not support. These can sometimes be the the cause of bugs, but others may be harmless. Best to report these to the KVM community, with details about your host hardware CPU models, and what guest OS you are running Regards, Daniel -- |: https://berrange.com -o- https://www.flickr.com/photos/dberrange :| |: https://libvirt.org -o- https://fstop138.berrange.com :| |: https://entangle-photo.org -o- https://www.instagram.com/dberrange :|
