How odd. One difference between pvops time handling and the -xen kernels, is that they defaulted to slaving the domU time off the hypervisor at all times, so a system time change would propagate into guests. I don't implement that in pvops kernels, so they'll maintain independent time unless you explicitly sync with some mechanism like ntp.hmm...does this mean, that i have to use ntp in domU if i use the pvops kernel? Because time changes in dom0 doesnt propagate into domUs? It will set its initial time-of-day clock from the hypervisor's at boot, but then proceed independently (but the timebase is derived from the hypervisor's clock). If you want it to track a reference, you need to run ntp. J _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
