hi stefano, hi konrad, thanks for replying :-) i followed your suggestions and changed the guest config file. I have now the following test szenario: server01 > should be a debian squeeze 6.0.1a amd64 netinst installation server02 > is a successfully installed windows 7 x64 installation bellow I paste the both config files. as you can see from the screen shots: server01 installation ********************* sh11: server01_debian-installer-1.JPG sh12: server01_debian-installer-2.JPG sh13: server01_debian-installer-3.JPG the debian installation has some difficulties to find a harddisk. strange is, that the networkcard was found straight away and I became a dhcp lease from my infrastructure. server02 installation ********************* sh21: server02_xen_win7.JPG the windows has been successfully installed onto my xen guest, but!!!!! Q U E S T I O N S ***************** - why do I see my server HP DL320G5 network card and disk controller? - I thought, HVM means fully virtualized?! I expected to see something like qemu/xen harddrive and qemu/xen network card!? - Is here my xen really doing HVM - how can I do HVM, I need my guests to be transferred to any different hw boxes without need to deal with guest disk and network card drivers? many thanks, walter server01 ******** name = 'server01' kernel = 'hvmloader' builder = 'hvm' device_model = 'qemu-dm' maxmem = 1024 memory = 1024 vcpus = 1 acpi = 1 apic = 1 vif = [ 'bridge=eth0' ] disk = [ 'phy:/dev/vgmain/lv_server01,hda,w','file:/var/xen/debian-6.0.1a-amd64-netin st.iso,hdc:cdrom,r' ] boot = 'cd' usbdevice = 'tablet' sdl = 0 stdvga = 1 serial = 'pty' ne2000 = 1 on_poweroff = 'destroy' on_reboot = 'restart' on_crash = 'restart' vnc = 1 vnclisten = '0.0.0.0' vncviewer = 1 *** server02 ******** name = 'server02' kernel = 'hvmloader' builder = 'hvm' device_model = 'qemu-dm' maxmem = 1024 memory = 1024 vcpus = 1 acpi = 1 apic = 1 vif = [ 'bridge=eth0' ] disk = [ 'phy:/dev/vgmain/lv_server02,hda,w','file:/var/xen/win7.iso,hdc:cdrom,r' ] boot = 'cd' usbdevice = 'tablet' sdl = 0 stdvga = 1 serial = 'pty' on_poweroff = 'destroy' on_reboot = 'restart' on_crash = 'restart' vnc = 1 #vncunused = 0 vnclisten = '0.0.0.0' #vncdisplay = 2 #vncconsole = 1 #vncpasswd = '123456' vncviewer = 1 ne2000 = 1 *** -----Original Message----- From: Stefano Stabellini [mailto:stefano.stabellini@eu.citrix.com] Sent: Montag, 18.

Also it is probably not a good idea to disable acpi. > boot = 'cd' > usbdevice = 'tablet' > > extra = 'swiotlb=force iommu=soft' this is an hvm guest so extra is not going to do much, you need to pass these parameters directly to the guest kernel from grub if you want them.
