Hi folks,
I was doing some work at one of our host machines, the one that runs
upstream (Fedora 14, kvm.git as the kernel and qemu-kvm.git as
userspace), and I noticed the kernel message:
kvm: unreliable cycle conversion on adjustable rate TSC
kvm: SMP vm created on host with unstable TSC: guest TSC will not be
reliable
Yes, the message is a warning; without TSC trapping, SMP VMs will have
unreliable TSC. In this case, you are advised to use kvmclock or
another non-TSC clocksource in the guest.
