[Xen-devel] how does xen perform the virtual cpu time accounting and metering of domU?
Hi all, how does xen perform the virtual cpu time accounting and metering of domU? Is there any key function to do this? Is it from virtual timer IRQ or sth else? How does xen deal with the physical timer interrupt? Which function is associated to this? Is this related to domU's CPU time accounting? xm list cmd show the virtual cpu time of domU. Which variable is this cpu time information located in xen tools? Which variable in xen does the xen tools get the CPU time of each domain?
