I’m running a debian based XEN box to host various virtual machines. Lately I’ve been having an issue when running update-grub. All the partitions for the virtual machines are found and added to grub:
1 2 3 4 5 6 | # update-grub2 [...] Found Debian GNU/Linux (7.7) on /dev/mapper/vg0-vm01--disk Found Debian GNU/Linux (7.7) on /dev/mapper/vg0-vm02--disk Found Slackware Linux (Slackware 14.1) on /dev/mapper/vg0-vm03--disk [...] |
It’s not a big issue as the xen kernel is still default but it’s annoying. Turns out the fix is simple enough, you have to add one line to /etc/default/grub like this:
1 | GRUB_DISABLE_OS_PROBER=true |
After that re-run update-grub
