I found that support for setting autostart parameters for xend managed guests has been added to libvirt
(https://www.redhat.com/archives/libvir-list/2008-May/msg00060.html)

So I tried that but failed with virsh's autostart command (and also virt-manager) like this:

virsh # autostart saruman
libvir: Xen Daemon error : POST operation failed: (xend.err "Error creating domain: VM name 'saruman' already exists as domain 32") libvir: Xen Daemon error : failed Xen syscall Failed to redefine sexpr 6508560
error: Failed to mark domain saruman as autostarted


So yes, the domain is indeed running but I understood it should be changeable during a domain's lifetime.

Any ideas?
That is a libvirt CVS snapshot from yesterday and a Xen 3.1 installation.

Hmm, I thought redefining the sexpr in place was an a-okay thing to do,
and this worked on my f8 machine. I'll look into this.

Yes it is an OK thing todo. It is explicitly supported as it is *required*
in order todo installations - we boot the guest with the install config,
and defnie the guest with its persistent config. What exact version of Xen
is being used here ? It looks like it has overzealous duplicate checking

The Xen package is called 3.1.0_15042 and is packaged with openSUSE 10.3.

Thanks,
Wolfgang
