Bug Description
Binary package hint: qemu-kvm
The qemu package in 10.04 LTS (0.12.3) has a bug which corrupts virtio disks 2TB and larger. This is corrected in qemu 0.12.5, which is present in 10.10. The corruption happens quickly, after about 80GB of files copied, with no I/O errors on the host or the guest VM.
There are more details in the redhat bug report https:/
I believe that this is something that should be fixed for LTS.

In my situation, the ext4 filesystem detected something was wrong and re-mounted the fs read only.
