Hi, folks,
I've got two problems with grub2 that I thought others might have solved already. My initial attempts haven't been fruitful.
I have an f20 Dom0.
xen-4.3.2-1.fc20.x86_64
grub2-2.00-25.fc20.x86_64
Problem #1
My /etc/default/grub looks like [1].
I try to set the Dom0 to boot with:
grub2-set-default 'Fedora, with Xen 4.3.2 and Linux 3.12.10-300.fc20.x86_64'
and the default non-Xen menuentry gets booted instead.
It's definitely there in the config file [2] and I can boot it manually. I really need the machine to be able to boot unattended. I tried setting it manually in /etc/grub/default but that doesn't work either.
I'm generating the grub.cfg with grub2-mkconfig > /boot/grub2/grub.cfg and have re-installed grub2 on my /dev/sda and /dev/sdb (raid-1 /boot).
Problem #2
When I try to boot from grub manually, I first get an error message saying "xen_rm_opts" unknown command. In each Xen menuentry, I see, e.g.:
echo 'Loading Xen xen ...'
if [ "$grub_platform" = "pc" -o "$grub_platform" = "" ]; then
xen_rm_opts
else
xen_rm_opts="no-real-mode edd=off"
fi
whereas in previous times I remember the first conditional block saying:
xen_rm_opts=
I presume that makes the difference between a statement and an assignment in whatever sh-ish language grub is using. I'm not sure where to fix that as I'm no grub2 expert. I kinda miss the simplicity of 'default=6'. :)
My third possible-grub problem relates to memory and I'm not sure it really is a problem in grub2 yet, so I'll post that separately.
Thanks in advance!
