Hi, all I''m using NBD to install HVM in xen 3.4.0, the following is my HVM config file. #cat /etc/xen/hvm1conf import os, re arch_libdir = ''lib'' arch = os.uname()[4] if os.uname()[0] == ''Linux'' and re.search(''64'', arch): arch_libdir = ''lib64'' kernel = "/usr/lib/xen/boot/hvmloader" builder=''hvm'' memory = 512 name = "hvm1" vif = [ ''type=ioemu, bridge=eth0'' ] disk = [ ''file:/home/chenpeng/tmp/hvm1disk,hda,w'', ''nbd:192.168.1.109 9000,hdc:cdrom,r'' ] device_model = ''/usr/'' + arch_libdir + ''/xen/bin/qemu-dm'' boot="d" sdl=0 opengl=1 vnc=1 vnclisten="0.0.0.0" vncconsole=1 vncpasswd='''' stdvga=0 serial=''pty'' usb=1 usbdevice=''mouse'' usbdevice=''tablet'' On my nbd-server, I have exported an iso file on port 9000. When I type #xm cr /etc/xen/hvm1conf, I got the following error message. Error: Device 5632 (vbd) could not be connected. /etc/xen/scripts/block failed; error detected. 2009-08-31 Chen Peng _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
