OpenBSD’s NTPD inside a Debian domU

To get the package openntpd installed was easy, but to get it to work, required some search. In order to have a domU use an independent clock, you have to set a kernel variable. In a running system you do this via the following line:

echo 1 > /proc/sys/xen/independent_wallclock

and to make this setting persistent, add the following line to your /etc/sysctl.conf:

xen.independent_wallclock = 1

Then restart the OpenBSD NTP daemon or install it just after those changes. This will ensure that NTP works properly. Before, I got no complaints from the daemon or in the log files, but the time was off by ~2:10 min … in each and every domU.
