But after more than 24h, the 2'17 gap between hwclock and date has not reduced a bit. I guess this is not the place for me to debug my ntp issues, apart maybe from what could be related to the virtualization itself. I understood from my readings (can't remember where precisely) that the fact that ntp wouldn't work was "normal", but if it is not, maybe trying to have it working is the way to go, rather than searching for a way to automatize guest-set-time. -- Jérôme _______________________________________________ libvirt-users mailing list libvirt-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvirt-users
