crash does not support recent qemu save-vm formats

Hi,

I've been trying to diagnose a livelock-like condition (no response to ping, serial console dead, KVM process consumes 100% CPU) of KVM virtual machines on Ubuntu 9.10 (Ubuntu AMD64 kernel 2.6.31-17-server, QEMU 0.11.0 and libvirt 0.7.0).

"virsh dump" generates a dump file that crash cannot read:

crash: qemu-load.c:501: cpu_init_load_64: Assertion `version_id >= 4 && version_id <= 9' failed.

Indeed, CPU_SAVE_VERSION in this dump file is 10.
