Hi all, I have installed a CentOS-8 server to accomplish some tests using kvm guests … All these guests are centos8 also. When these guests starts, I always see errors like: [ 589.687915] kvm [2133]: vcpu0, guest rIP: 0xffffffff81a5bc98 disabled perfctr wrmsr: 0xc2 data 0xffff [ 596.210773] kvm [2201]: vcpu0, guest rIP: 0xffffffffb885bc98 disabled perfctr wrmsr: 0xc2 data 0xffff Is this a bug? I am not using virt-manager to create guests configuration … Any idea? Kernel release is: 4.18.0-80.11.2 -- Regards, C. L. Martinez
