Recently Grub has been changing to a high resolution mode. On some systems this is really slow, presumably due to having a crap BIOS. On kvm/qemu systems it doesn't work with -display curses.
How do I get grub to stick to 80x25 text?
On Debian, Ubuntu etc, edit /etc/default/grub and 1. un-comment the line: GRUB_TERMINAL=console 2. optionally comment out the line starting with: GRUB_GFXMODE= (i can't remember if this is required or not. I think it isn't) 3. save & exit, run "update-grub" On non-debian machines, dunno. probably fuck around with files in /etc/grub.d/ BTW, for kvm you might also want to enable a serial console. I usually enable two serial consoles per VM, one to log the VM's boot up to a text file on the host, the other for console access with 'virsh console' (this is also how console access is provided in a javascript web by openstack and similar virtualisation wrapper systems). Remember to actually configure both grub and a getty (via inittab or systemd) to use the serial console as well as adding the console "hardware" to the VM. craig -- craig sanders <cas@taz.net.au>
