Hi, 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. Thanks, Wolfgang
