I will explain it step by step what solved my problem which works for both, win7 and debian squeeze guest's: network card / network ********************** the guest network works brilliant only with that configuration: auto brX iface brX inet static address 10.41.10.42 netmask 255.255.255.0 network 10.41.10.0 broadcast 10.41.10.255 gateway 10.41.10.1 bridge_ports eth0 bridge_stp on bridge_maxwait 0 vif = [ 'bridge=brX,mac=xx:xx:xx:xx:xx:xx' ] strange is that I now have to configure a bridge interface. with older xen version it was enough to setup "bridge=eth0". now I had to setup "bridge=brX"! disk controller *************** for a windows 7 x64 guest system I got it running with: disk = [ 'phy:/dev/vgmain/lv_server01,hda,w','file:/var/xen/win7.iso,hdc:cdrom,r' ] for a debian squeeze guest system I needed to change it into: disk = [ 'phy:/dev/vgmain/lv_server01,sda,w','file:/var/xen/debian-6.0.1a-amd64-netin st.iso,hdc:cdrom,r' ] even here is strange that debian squeeze guest's now see the qemu disk as a "SDA". squeeze used to see qemu disk in older xen versions (< 4.2) as "HDA" and that definitely doesn't work anymore. I found that out having a deeper look at the debian installer log. guy's, thank you very much for your help, had become a lot of new input's. I hope I could give some useful feedback back to you too. finally I only would like to know, if this SDA-behavior is now a new behavior of xen 4.2 ++? thanks a lot, walter *** original guest config file *** name = 'server01' kernel = 'hvmloader' builder = 'hvm' device_model = 'qemu-dm' maxmem = 1024 memory = 1024 vcpus = 1 acpi = 1 apic = 1 vif = [ 'bridge=eth0,mac=00:16:3e:1a:b3:4b' ] #vfb = [ 'type=vnc,vnclisten=0.0.0.0,vncunused=0,vncdisplay=1' ] disk = [ 'phy:/dev/vgmain/lv_server01,hda,w','file:/var/xen/debian-6.0.1a-amd64-netin st.iso,hdc:cdrom,r' ] boot = 'dc' usbdevice = 'tablet' sdl = 0 stdvga = 1 serial = 'pty' on_poweroff = 'destroy' on_reboot = 'restart' on_crash = 'restart' vnc = 1 vnclisten = '0.0.0.0' vncviewer = 1 *** -----Original Message----- From: Stefano Stabellini [mailto:stefano.stabellini@eu.citrix.com] Sent: Mittwoch, 20.

What exactly are the network card and disk controller that you are seeing in your guests?
