Hi All,

I have just started looking at the code for Xen so please bear with me.

A domU Linux kernel running with independent_wallclock=1 seems to sync
its time with dom0 after every "xm unpause" (obviously preceded by an
"xm pause").

I don't see where the xtime variable is being updated after an "xm
unpause", i.e., domain_unpause_by_systemcontroller(). Right after the
unpause, it seems to me that the xtime in the domU should be what it
were just prior to the pause.

Any response would be greatly appreciated.
