Sorry I'm not sure I understood right - are you saying that you first reboot the guest through the menus in virt-manager, then the next time by running 'reboot' logged into the guest through ssh? As I can't reproduce this yet, it's possible I just need to follow your precise steps more closely.
Your guests are also x86-64 right?
