[xenpreview-dev] Fix for Xen Paravirtualized Guest Installation (SLES 10 Beta 10 / SL 10.1 RC1)

[Clyde Griffin]

There are two major Xen issues in SLES 10 Beta 10 and SUSE Linux 10.1
RC1.  Workarounds are described below.  Please pass this email on to
anyone doing SUSE Linux testing with Xen.  

First Issue:
The /boot/grub/menu.lst entry for booting the Xen hypervisor may not
get created automatically.  

Workaround:
1) Run the YaST "Virtual Machine Management (Xen)" tool in the YaST
"System" category to install the Xen hypervisor and kernel modules. 
(One time only.)
2) Add an entry to /boot/grub/menu.lst that looks like the example
below.  (Please refer to your existing menu.lst for specifics.)
3) Reboot and select Xen at the Grub menu.

Second Issue:
SLES 10 Beta 10 and SUSE Linux 10.1 RC1 paravirtualized guest
installations do not work in the official builds.  

Workaround:
1) Create an install source.
2) Replace the install-initrd... RPM in your install source tree with
the appropriate RPM located on the Novell/SUSE Xen Technical Preview
site at 
http://forge.novell.com/modules/xfmod/project/?xenpreview 
(install-initrd-1.0-14.i586.rpm or install-initrd-1.0-14.x86_64.rpm.)
3) Run the YaST "Virtual Machine Management (Xen)" tool in the YaST
"System" category to install a paravirtualized guest.
