Re: [Xen-devel] Why set time on dom0, but takes no effect on

["xiaoyun.maoxy" <xiaoyun.maoxy@xxxxxxxxxxxxxx>]

Thanks

First I get this when run in domain 0.

root@xmao # hwclock --debug
hwclock from util-linux-2.13-pre7
hwclock: Open of /dev/rtc failed, errno=19: No such device.
No usable clock interface found.
Cannot access the Hardware Clock via any known method.

Later I follow

But after reboot, time is still the old one
