Re: [Xen-users] Xen 3.4.2 on kernel 2.6.32.8 on Lenny

[Dot Yet <dot.yet@xxxxxxxxx>]

Hi Everyone,

Thanks for all the inputs. I am trying to work with Jeremy's
repository with xen 3.4.2 source.

The compilation for kernel 2.6.31.6 as well as xen happens fine. The
system boots fine too. But xend does not start. Earlier, it was
complaining about /proc/xen/capabilities not being present, fixed that
error by adding xenfs to /etc/fstab.

Now, its giving the following error about port 111. I noticed that
portmap service is running on that port. Can you help me find whats
wrong here?

Any help is appreciated.
