Hi Xiantao, The Guest network enabling patch has not been checked in by Avi. So we can not get network in VTI guest. We appended the patch and gave a verification for the other four P1 bugs. They are still existing in the latest commit: kernel-ia64: ec7c27790e75397e1e91488a18beadc60926e818 kvm-userspace: 619ca34310a8968b6939fa6aba5b85a16b20315e Bugs info: ==================== [KVM-IPF] guest domain can not boot up network http://otc-qa.sh.intel.com/kvm/bugzilla/show_bug.cgi?id=73 1.[KVM-IPF] FAIL to boot up Windows-2008server guest http://otc-qa.sh.intel.com/kvm/bugzilla/show_bug.cgi?id=85 2.[KVM-IPF] IA64-KVM Guest will crash at restore http://otc-qa.sh.intel.com/kvm/bugzilla/show_bug.cgi?id=95 3.[KVM-IPF] Guest can not be booted with > 2 vcpus http://otc-qa.sh.intel.com/kvm/bugzilla/show_bug.cgi?id=96 4.[KVM-IPF] Can not boot up guest with 4G memory http://otc-qa.sh.intel.com/kvm/bugzilla/show_bug.cgi?id=97 ==================== BTW Xiantao, could you please have a look at 3 trivial issues which does not happen on x86 arch. [issue1] "qemu-system-ia64 -hda ***.img" will report error "Unknown network device: user". [issue2] the default memory (128M) by qemu-system-ia64 can not boot up VTI guest, for it will reserve 100M. [issue3] When we type booting command in PUTTY, it will complain "Could not initialize SDL -exiting". (only for ia64 side) Thanks, Zhang Jingke -- To unsubscribe from this list: send the line "unsubscribe kvm-ia64" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
