Severity: normal
Hi,
grub2 does not add entries for xen hypervisor and kernels. After
reading the docs I managed to create an entry manually like this:
menuentry "Xen 3.4, kernel 2.6.31.5 git 20091113" {
insmod ext2
set root=(hd0,1)
search --no-floppy --fs-uuid --set 69c9f9d8-4772-4391-9111-e66ef6b49ac6
multiboot /xen-3.4-amd64.gz dom0_mem=512M
module /vmlinuz-2.6.31.5-xen-00513-g47dfde5 nomodeset
module /initrd.gz
}
I would suggest adding new variables to /etc/default/grub:
# Options for the xen hypervisor and kernel command line
#GRUB_CMDLINE_XEN_HYPERVISOR="dom0_mem=512M"
GRUB_CMDLINE_XEN_KERNEL="nomodeset"
and this in 10_linux ($3 == /boot/xen-3.4-amd64.gz for example):
xen_linux_entry ()
{
cat << EOF
menuentry "$1" {
EOF
prepare_grub_to_access_device ${GRUB_DEVICE_BOOT} | sed -e "s/^/\t/"
cat << EOF
multiboot ${rel_dirname}/"$3" ${GRUB_CMDLINE_XEN_HYPERVISOR}
module ${rel_dirname}/${basename}
root=${linux_root_device_thisversion} ro $2
EOF
if test -n "${initrd}" ; then
cat << EOF
module ${rel_dirname}/${initrd}
EOF
fi
cat << EOF
}
EOF
}
Now the tricky part is when to call that. There can be multiple
hypervisors installed (/boot/xen-<x>.<y>-<flavour>.gz). Also multiple
kernels (/boot/vmlinuz-*xen*). Xen kernels can also be for domU or
dom0+domU. In dom0 adding a domU kernel makes no sense. On the other
hand in domU adding non-xen kernels makes little sense.
So maybe /etc/defaults/grub should have a variable listing the pattern
for images that should be added:
# Add a menuentry for every linux kernel:
GRUB_PATTERN_LINUX="vmlinu[xz]*"
# Add a menuentry for every xen kernel:
GRUB_PATTERN_XEN="vmlinu[xz]*xen*"
# Add a menuentry only for dom0 xen kernel:
#GRUB_PATTERN_XEN="vmlinu[xz]*xen0*"
# Add a menuentry only for domU xen kernel:
#GRUB_PATTERN_XEN="vmlinu[xz]*xenu*"
and 10_linux could then use those to build its list of images.
How does that sound? Should I prepare a patch along those lines?
