Just uploaded a fix to the pvetest repository:

# wget http://download.proxmox.com/debian/dists/squeeze/pvetest/binary-amd64/pve-manager_2.1-3_all.deb
# dpkg -i pve-manager_2.1-3_all.deb

shutdown guest then use "stop backup mode"

So the title should be "In snapshot mode ,vzdump kvm guest clone with stdout parameter, run error"
