Failed to restart the vm

Description of problem:
I reboot a virtual machine(para-virt)  using two different methods: click the reboot button and input reboot in terminal of the guest. But the vm can't restart successfully with both methods. 
 After reboot, the vm still run but can't restart, and there's a prompt
says: Console not configured for guest"(Please catch the attachment). So I click
the "Hardware" tab, and find "Display" disappears. But if I force off this vm,
and run it again, it will restart successfully. And the "Display" hardware will
appear again.

terminal
