Hi, at the moment I am running this HVM guest config: disk = [ ''phy:/dev/vg/hera_1,ioemu:hda,w'',''phy:/dev/vg/hera_2,ioemu:hdb,w'',''phy:/dev/vg/hera_3,ioemu:hdc,w'',''file:/iso/win2003cd1.iso,hdd:cdrom,r''] So I am not able to add any extra drives. I tried this config: disk = [ ''phy:/dev/vg/hera_1,ioemu:sda,w'',''phy:/dev/vg/hera_2,ioemu:sdb,w'',''phy:/dev/vg/hera_3,ioemu:sdc,w'',''file:/iso/win2003cd1.iso,hdc:cdrom,r''] But after Windows 2003 Server booted from CD and installed all files the disks are not working after the first reboot. The driver windows 2003 uses is "sym_hi". Is it possible to use SCSI on a HVM guest? If yes how to change the virtual SCSI hardware used? greetings Flo _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
