-Elilo update for Xen/ia64 HowTo 9/20/2005
+Elilo update for Xen/ia64 HowTo 2005/12/01
+
+ Xen support is committed to ELILO CVS as of Dec 1, 2005. This support
+ should be in version 3.5pre2 when it is made available. To build from
+ source:
1. Build the new elilo
- a. Get the elilo RPM
-
http://fedora.mirrors.pair.com/linux/core/development/SRPMS/elilo-3.4-11.src.rpm
-
- b. Get the elilo-3.4.11.xen.patch
-
- c. Create elilo development tree
- > mkdir elilo
- > cd elilo
- > rpm2cpio ../elilo-3.4-11.src.rpm | cpio -div
- > tar xvfz elilo-3.4.tar.gz
- > cd elilo-3.4
- > // read elilo.spc for deatiled patch steps
- > patch -p1 < ../elilo-3.3a-makefile.patch
- > patch -p1 < ../elilo-3.4-debug.patch
- > patch -p2 < ../elilo-initrd-size-fix.patch
- > patch -p1 < ../elilo-argv-fix.patch
- > patch -p1 < ../elilo-kill-warnings.patch
- > patch -p1 < ../../elilo-3.4.11.xen.patch
- > make <=== get the elilo.efi
+ a. Get current elilo CVS from http://sourceforge.net/projects/elilo
+ b. make (Note that gnu-efi is a build dependency)
2. How to run with the new elilo.efi?
a. Example to run
modify elilo.conf with following entry
- image=XenoLinux.uncompressed
+ image=XenoLinux.gz
label=xen
vmm=xen.gz
