I sloved the problem. I modify the libvirt /src/qemu_conf.c. Add the arch ia64 into the

static const struct qemu_arch_info const arch_info_hvm[] = {}
as berrange said. So the libvirt passing -M ia64.

But the kvm binary only experts '-M itanium'.

So i replaced the ia64 by itanium in the file /src/qemu_conf.c. 

Then the virt-manager finally could work on the arch of Itanium.

Thank you for your help.

Thank you, everyone here.
