Hi list After I install xen4.0 in my debian squeezz,it added the following lines into /boot/grub/grub.cfg ### BEGIN /etc/grub.d/20_linux_xen ### menuentry ''Debian GNU/Linux, with Linux 2.6.32-5-xen-amd64 and XEN 4.0-amd64'' --class debian --class gnu-linux --class gnu --class os --class xen { insmod part_msdos insmod ext2 set root=''(hd0,msdos1)'' search --no-floppy --fs-uuid --set ae156f58-edec-4972-bd1c-d6f37a473ddd echo ''Loading Linux 2.6.32-5-xen-amd64 ...'' multiboot /boot/xen-4.0-amd64.gz placeholder module /boot/vmlinuz-2.6.32-5-xen-amd64 placeholder root=UUID=ae156f58-edec-4972-bd1c-d6f37a473ddd ro quiet echo ''Loading initial ramdisk ...'' module /boot/initrd.img-2.6.32-5-xen-amd64 } ### END /etc/grub.d/20_linux_xen ### when I started a VM created by xen , it showed errors: ~~~~~~~~~~~~~~~~~~~~~~~~~~| DirectFB 1.2.10 |~~~~~~~~~~~~~~~~~~~~~~~~~~ (c) 2001-2008 The world wide DirectFB Open Source Community (c) 2000-2004 Convergence (integrated media) GmbH ---------------------------------------------------------------- (*) DirectFB/Core: Single Application Core.

DirectFB/Core: Could not initialize ''system_core'' core! --> Initialization error! Could not initialize SDL - exiting It seems that xen can not find the framebuffer device. I have searched the web about how to enable framebuffer in grub2,someone said : add these two lines into /etc/default/grub and run update-grub2 .(https://wiki.archlinux.org/index.php/GRUB2 ) GRUB_GFXMODE="1024x768x32" GRUB_GFXPAYLOAD_LINUX="keep" I have done it and reboot my server,but the problem remains. My question is : How to enable framebuffer in grub2? Thank you! 2011-05-23 sosogh _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
