Can you send the error message you are getting from Windows?

Vadim and I monitor qemu-devel, you can also open bug in bugzilla.redhat.com <http://bugzilla.redhat.com/> for virtio-win component or report an issue here: https://github.com/YanVugenfirer/kvm-guest-drivers-windows/issues <https://github.com/YanVugenfirer/kvm-guest-drivers-windows/issues> > > > Some more background for our migration procedure: > > - The VM was installed some years are on Xen. > - The GPLPV drivers were added afterwards. > - For the migration the GPLPV drivers were disabled and then removed. > - A 2nd VirtIO hard-disk was added in KVM to trigger Windows to request > the virstor driver. > > If you need any more data, just ask. > > Thanks in advance > Philipp Hahn > > PS: data was copied by hand from Windows, so it might contains > copy-paste-errors. > -- > Philipp Hahn > Open Source Software Engineer > > Univention GmbH > be open. > Mary-Somerville-Str. 1 > D-28359 Bremen > Tel.: +49 421 22232-0 > Fax : +49 421 22232-99 > h...@univention.de > > http://www.univention.de/ > Geschäftsführer: Peter H.
