Hello, I can confirm that there are problems with the clock in PV domUs. I've setups like as follows: * Debian lenny dom0s running Debian squeeze and Debian lenny domUs (PV) * Debian squeeze doms running Debian squeeze and Debian lenny domUs (PV) I only have clock/time problems with my squeeze domUs. They use 2.6.32-5-amd64 and 2.6.32-5-686 kernels from Debian squeeze. It doesn't matter if they run on lenny (2.6.26-*-xen-686) or squeeze (2.6.32-*-xen-686) dom0s. With my Debian lenny dom0s I've set clocksource=jiffies and my lenny domUs also have clocksource=jiffies and independent_wallclock set to 0. All is fine here. I've running ntpd on the dom0s and the domUs use the time from the dom0s. (I've tested to change the time in the dom0 and the time change also show up in the domUs.) so I've no Problems with lenny domUs and time. With debian squeeze there's no clocksource jiffies anymore, so I use the default clocksource=xen in squeeze doms and squeeze domUs. Also there's no independent_wallclock anymore. So here's the problem I see: The time in my squeeze domUs is running slightly slower than the time on my dom0. Changing the time on the dom0 doesn't change the time in the squeeze domUs. But I can run ntpdate/ntp in my squeeze domUs and time gets correct. I'm wondering if I can set the former behavior of the domU clock to use the dom0s clock? -- greetings eMHa
