I found that support for setting autostart parameters for xend managed

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
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
I just found the following patch which is applied to Xen 3.1 on openSUSE
which sounds like the culprit.
If you can confirm that I'm happy to report a bug over at openSUSE.
