Looks like it tries to read MSR_LASTBRANCH_TOS MSR which kvm does not
support. Do you see something interesting in dmesg? I wonder how
availability of the MSR should be checked.
You are right about the MSR. The log file from the time of occurrence
shows the following:
Jul 4 18:55:12 server kernel: [ 1528.618647] kvm: 3123: cpu1
kvm_set_msr_common: MSR_IA32_DEBUGCTLMSR 0x1, nop
Jul 4 18:55:12 server kernel: [ 1528.619444] kvm: 3123: cpu1
unhandled rdmsr: 0x1c9
You can try
$ rmmod kvm-intel kvm
$ modprobe kvm ignore_msrs=1
$ modprobe kvm-intel
(or kvm-amd, as the case may be)
This will work around the issue, but the application may not function
correctly.
