So I used good old Lilo instead. When running Suse in virt-manager Lilo fails with LILO - Keytable read/checksum error on bootup When I go kvm -m 512 -hda SLES-10.3.imglibvirt won't have such a simple command line. There could be other KVM options which affect things at boot. I have a couple of suggestions: (1) Find out the full libvirt command line. Easiest is to start the domain under virt-manager and quickly use the 'ps ax' command. (There is a more "official" way to convert libvirt XML into a qemu command line but I cannot recall what that is at the moment).
Smart! I did that and found out that it is the boot=on drive option that is the cause of the problem:
-drive file=/root/SLES-10.3.img,if=ide,index=0,boot=onFor some reason it only works when it is set to boot=off. I tried <boot>off</boot> and boot="off" in the target tag in the corresponding disk tag in the XML file, but with no luck. I also tried to remove the <boot dev='hd'/> from the os tag. I did do a "/etc/init.d/libvirt-bin reload" just in case. Is there any way to get control the boot option from the XML file?
(2) Use virt-rescue or guestfish and see if you can install grub in the domain. In guestfish it'd be something like this: guestfish -i GuestName ><fs> mkdir-p /boot/grub ><fs> grub-install /boot /dev/sda1 (You might need to change those command slightly and read the man page for virt-rescue, guestfish and/or grub-install).
Ok, thanks for the tip. I will consider it if it impossible to control the boot option as explained above. Or maybe I'll just settle with being annoyed and start the machine from the command line :)
