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.
