The Xen Interface manual for Xen v2.0 (attached) Page 4 defines Domain - virtual time as
" The time that progresses at the same pace as system time, but only while a domain is executing -- it stops while a domain is 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.
