CVS commit: src/sys/arch/xen/xen



Module Name:    src
Committed By:   tls
Date:           Fri Jul 16 22:36:33 UTC 2004

Modified Files:
        src/sys/arch/xen/xen: clock.c

Log Message:
Set the system clock (via Xen) in resettodr(), if domain 0.

This has a couple of beneficial effects:

1) The TOD time will be preserved across boots, as one would expect.

2) Newly-started VMs will get the correct time according to domain 0.
   Previously, since we never set the time back to Xen, each VM would
   get the uncorrected system clock time, never even seeing any
   changes made since the current startup.

I don't understand how XenoLinux slaves the other domain's clocks to
the Xen "wall clock" time that we're setting here, so I haven't even
tried.  But now we can run ntpd in each domain without a huge offset
at boot caused by never updating the wall clock time at all...
