Pleae help what needs to be do in this situation. You have not provided information on what is happening. Are you getting an error message during boot from the 1.2TB guest? Is the 1.2TB guest even being autostarted (use "virsh autostart <domain>" to enable autostart on a domain)? Please send support questions like this to qemu-devel@nongnu.org in the future.
