Is there some other guest OS that works w/ 2T qcow2? Did you had enough space on the host? You should have executed the command with werror=stop Please repeat the test with it.

Does this even work on real hardware? 2 TB is the maximum size for the MBR partition table, I wouldn't be surprised if at least RHEL 5 just didn't support that.

Today i tested another scenario. if i create a 2T-1M size images to install rhel5.7. it works fine.
Probably a guest problem. Closing.
