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://bugzilla.redhat.com/show_bug.cgi?id=605757.

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.

@Mark,

thanks for reporting this bug and helping to make Ubuntu better. I believe this is the same issue as bug 574665. Could you please verify (or refute) the proposed fix so we can get it SRU'd to lucid-proposed?

Serge,

You are correct -- this appears to be a duplicate. In the mean time, I will be running 0.12.5 on my servers.
