-Currently, kvm module is in EXPERIMENTAL stage on IA64. This means that
-interfaces are not stable enough to use. So, please don't run critical
-applications in virtual machine.
-We will try our best to improve it in future versions!
-
- Guide: How to boot up guests on kvm/ia64
-
-This guide is to describe how to enable kvm support for IA-64 systems.
-
-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/xiantao/kvm-ia64.git
-
-2. Compile the source code.
- 2.1 Compile userspace code:
- (1)cd ./kvm-userspace
- (2)./configure
- (3)cd kernel
- (4)make sync LINUX= $kernel_dir (kernel_dir is the directory of kernel source.)
- (5)cd ..
- (6)make qemu
- (7)cd qemu; make install
-
- 2.2 Compile kernel source code:
- (1) cd ./$kernel_dir
- (2) Make menuconfig
- (3) Enter into virtualization option, and choose kvm.
- (4) make
- (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 == 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, use it directly.
-
- (2) If you have no firmware at hand, Please download its source from
- hg clone http://xenbits.xensource.com/ext/efi-vfirmware.hg
- you can get the firmware's binary in the directory of efi-vfirmware.hg/binaries.
-
- (3) Rename the firmware you owned to Flash.fd, and copy it to /usr/local/share/qemu
-
-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 possible issue on some platforms with old Firmware.
-
-In the event of strange host crash issues, try to solve it through either of the following ways:
-
-(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.
- https://lists.sourceforge.net/lists/listinfo/kvm-ia64-devel/
-
-Thanks for your interest! Let's work together, and make kvm/ia64 stronger and stronger!
