Re: [Xen-devel] Xen timing mode

The Xen Interface manual for Xen v2.0 (attached) Page 4 defines Domain

de-scheduled. Therefore the share of the CPU that a domain receives is
indicated by the rate at which its virtual time increases."
I am interesting in finding out if any of the timing system
calls/instructions like gettimeofday(), hwclock(), rdtsc() can read
this domain virtual time.
/proc/stat publishes stolen time for each vcpu (second-last column on
the "cpuX" lines); you can subtract that from monotonic time to work out
how much vcpu the domain has got.
