http://serverfault.com – I'm trying to install Gentoo into a Xen HVM guest. Everything went fine with the install up to the point where you do the grub-install. Apparently, grub does not know about block devices labeled "xvd" (see https://bugs.gentoo.org/show_bug.cgi?id=424343). The initial error was: livecd# grub-install /dev/xvda /dev/xvda does not have any corresponding BIOS drive After patching the /sbin/grub-install to see xvd devices and modifying /boot/grub/device.map to be: (hd0) /dev/xvda I now get the following error: livecd# grub-install /dev/xvda df: Warning: cannot read table of mounted file (HowTos)
