+				Guide: How to boot up guests on kvm/ia64
+
+1. Get the kvm source from git.kernel.org.
+	Userspace source:
+		git clone
git://git.kernel.org/pub/scm/virt/kvm/kvm-userspace.git
+	Kernel Source:
+		git clone
git://git.kernel.org/pub/scm/linux/kernel/git/avi/kvm.git
+2. Compile the source code.
+	2.1 Compile userspace code:
+		(1)cd ./kvm-userspace
+		(2)./configure
+		(3)cd kernel
+		(4)make sync LINUX=3D $kernel_dir (kernel_dir is the
directory of kernel source.)
+		(5)cd ..
+		(6)make qemu
+		(7)cd qemu; make install
+	2.2 Compile kernel source code:
+		(1) cd ./$kernel_dir
+		(2) Make menuconfig=20
+		(3) Enter into virtualization option, and choose kvm.
+		(4) make=20
+		(5) Once (4) done, make modules_install
+		(6) Make initrd, and use new kernel to reboot up host
machine.
+		(7) Once (6) done, cd $kernel_dir/arch/ia64/kvm
+		(8) insmod kvm.ko; insmod kvm-intel.ko
+
+Note: For step 2, please make sure that host page size =3D=3D
TARGET_PAGE_SIZE of qemu, otherwise, may fail.
+
+3. Get Guest Firmware named as Flash.fd, and put it under right place:
+	(1) If you have the guest firmware (binary)released by Intel
Corp for Xen, you can use it directly.
+	(2) If you want to build a guest firmware form souce code.
Please download the source from
+		hg clone
http://xenbits.xensource.com/ext/efi-vfirmware.hg
+		Use the Guide of the source to build open Guest
Firmware.
+	(3) Rename it to Flash.fd, and copy it to /usr/local/share/qemu
+Note: For step 3, kvm use the guest firmware which complies with the
one Xen uses.
+
+4. Boot up Linux or Windows guests:
+	4.1 Create or install a image for guest boot. If you have xen
experience, it should be easy.
+
+	4.2 Boot up guests use the following command.
+		/usr/local/bin/qemu-system-ia64 -smp xx -m 512 -hda
$your_image
+		(xx is the number of virtual processors for the guest,
now the maximum value is 4)
+
+5. Known possbile issue on some platforms with old Firmware
+
+If meet strange host crashes, you may try to solve it through either of
the following methods.
+(1): Upgrade your Firmware to the latest one.
+
+(2): Applying the below patch to kernel source.

+6. Bug report:
+	If you found any issues when use kvm/ia64, Please post the bug
info to kvm-ia64-devel mailing list.

+Thanks for your interest! Let's work together, and make kvm/ia64
stronger and stronger!=20
