KVM Guest time management

KVM Guest time management

Host has TSC capability

cat /proc/cpuinfo | grep constant_tsc

The Network Time Protocol (NTP) daemon should be running on the host and the guest virtual machines.

Check current clock source

cat /sys/devices/system/clocksource/clocksource0/current_clocksource 

Host = tsc

Guest = kvm_clock
