== Using Legacy pvgrub == | |||
To use Legacy pvgrub you need to use a {{path|/boot/grub/menu.lst}} instead of {{path|/boot/grub/grub.cfg}}. | |||
{{cat | /etc/xen/a1.cfg |<nowiki>default 0 | |||
timeout 2 | |||
title alpine-xen-pv | |||
root (hd0,0) | |||
kernel /boot/vmlinuz-virt root=/dev/xvda3 modules=ext4 console=hvc0 | |||
initrd /boot/initramfs-virt | |||
</nowiki>}} | |||
And in {{path|/etc/xen/a1.cfg}} you need to change the 'kernel' loader to | |||
{{cat | /etc/xen/a1.cfg |<nowiki>... | |||
kernel = "/usr/lib/xen/boot/pv-grub-x86_64.gz" | |||
... | |||
</nowiki>}} | |||
