akerb:~ # dmesg | grep kvm-clock
[ 0.000000] kvm-clock: Using msrs 4b564d01 and 4b564d00
[ 0.000000] kvm-clock: cpu 0, msr 1:3ff18001, boot clock
[ 0.000000] kvm-clock: cpu 0, msr 1:3ff18001, primary cpu clock
[ 0.004000] kvm-clock: cpu 1, msr 1:3ff18041, secondary cpu clock
[ 0.004000] kvm-clock: cpu 2, msr 1:3ff18081, secondary cpu clock
[ 0.004000] kvm-clock: cpu 3, msr 1:3ff180c1, secondary cpu clock
[ 0.134685] Switched to clocksource kvm-clock
This is the client
root# cat /sys/devices/system/clocksource/clocksource0/current_clocksource
I have on the Server
tsc
This is a original YaSt Installation
can I change this manual ?
