oki its over.
after some fail of updating a (host) nic driver under windows, i got kvm equipment connected and made a fresh install from cd.
sure now theres everything up-to-date, even vmware server is now in version2.
the old virtual machines all ran exept the router for the gameservers had some packet loss.
no coccinella septempunctata so far from here to report.
the solution was btw to have a new driver for the NICs in VM.
thx for being strong in lagi times, at least it seems to have a positive effect for creativity
