I'm guessing there's a problem with timers or timer interrupts.
What is the host cpu?
4 entries like this in /proc/cpuinfo:
processor : 3
vendor_id : AuthenticAMD
cpu family : 15
model : 65
model name : Dual-Core AMD Opteron(tm) Processor 2212
That's probably the kvmclock issue that hit older AMDs. It was fixed
in kvm-84, please try that.
I've been running it for about a week now with kvm-84 and no guest got
slow.
Can it be related to using cpufreq and ondemand governor?
Something fishy here :(
After a week or so, network in one guest got slow with kvm-84 and no
cpufreq.
