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

just out of curiosity, 0.12.5 works well, why not just use it? even dist-upgrade to 10.10 which has 0.12.5 would probably be less painful than having to test/deal with this bug. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm

Seems more tricky to patch than expected, more things contributing to this defect. There was some regression on gentoo as well, patched/fixed in -r1 and re-introduced in -r2 although the previous patch was in. Most efficient solution will be not to patch. Update to 0.12.5 which fixes the problem

@steven: what you're describing seems to be a different issue though, sounds rather host related. anyway the whole ide guest story is a bit offtopic here, Ill open a new bug for this as soon as I have time to do more tests. -- kvm + virtio disk corrupts large volumes (>1TB). https://bugs.launch

try to patch qemu-kvm 0.12.4, seemed to me there were other changes contributing to this fix in 0.12.4. I verified that it works on gentoo http://bugs.gentoo.org/show_bug.cgi?id=321005, at least using 1.5TB disk. ** Bug watch added: Gentoo Bugzilla #321005 http://bugs.gentoo.org/show_bug.cgi?

yes, writing is not enough though. try copying 60 GB from one ide disk to another. there's plenty of those ata exception bugs floating around, I just picked the closest example. failures during WRITE_DMA_EXT are most common. -- kvm + virtio disk corrupts large volumes (>1TB). https://bugs.laun

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 proces
