[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v3] xen/pygrub: grub2/grub.cfg from RHEL 7 has new commands in menuentry.
menuentry in grub2/grub.cfg uses linux16 and initrd16 commands
instead of linux and initrd. Due to this RHEL 7 (beta) guest failed to
boot after the installation.
In addition to this, menuentry has some options as well
(--class red, --class gnu, etc).
Signed-off-by: Joby Poriyath <joby.poriyath@xxxxxxxxxx>
Reviewed-by: Andrew Cooper <andrew.cooper3@xxxxxxxxxx>
v2: Added RHEL 7 grub.cfg in pygrub/examples
v3: Tidied the commit message.
Kindly consider this patch for xen-4.4 as RHEL 7 (beta) fails
to boot on Xen.
