I don't have access to a running Suse SLES, but I am wondering if the 
documentation is up to date.
What I know is that pv_ops kernel in Debian squeeze do not have 
independent_wallclock.
I have not been able to find something related to an independent_wallclock
parameter in a vanilla Linux 3.2 kernel either.

In addition, there is a lot of ressources available on Internet stating 
that independent_wallclock does not exist on pv_ops kernel anymore, 
starting with http://wiki.debian.org/Xen.

Thanks. However, I think the table headers a bit misleading, because in

> Classic XenoLinux Kern (up to 2.6.37)
2.6.37 relates to the kernel version, whereas in

> Paravirt Ops Linux Kern (from 3.0)
it seems to be related to Xen version, if I am not mistaken.
