[Bug 574665] Re: kvm + virtio disk corrupts large volumes (>1TB).

[masc]

Even though there's no corruption, ide cannot be considered an
acceptable workaround with kvm.

Ata exceptions will occur mostly when writing large files. (eg.
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/279693). Proposed
workarounds like putting cd in drive don't work with kvm. All processes
which currently have io requests pending will freeze for ~10 seconds
when this happens. And it does, a lot.
