guest rhel5.7 installation error
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.

boot guest rhel5.7 64bit with werror=stop option, still have the same issue. host free space is 64G.

boot guest rhel6.2 fails with 2T size image
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.

we have no real hardware that support 2T disk. so i am not sure if it works in real hardware. 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.
