[Bug 404394] Re: kvm-84: virtio on qcow2 broken (regression)
I revoke my previous comments. Meanwhile it turned out that the server I was testing with had HW problems (namely it couldn't handle 6x2GB RAM despite of the motherboard docs claiming it would). So my error reports are unreliable ... they might have been caused by HW issues. -- kvm-84: virtio on qcow2 broken (regression) https://bugs.launchpad.net/bugs/404394 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to kvm in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 404394] Re: kvm-84: virtio on qcow2 broken (regression)
I hope I'm not getting lynched :-), but I'd like to reopen this bug as not fixed. Previously you wrote that Karmic is not affected, however I've experienced filesystem corruption inside qcow2 images. It's a bit hard to reproduce since I had it in Windows 2003 guests, but I'll try to create a test case with an Ubuntu (eg. Karmic) guest too. The host OS is Ubuntu 9.10 Karmic and kvm is version 84+dfsg-0ubuntu16+0.11.0+0ubuntu6.3. The corruption occurs only during high I/O (as described by others before). It's irrelevant whether the high I/O is in the host OS or in the guest. I'll post again once I've an easily reproduceable test case, preferably in a linux guest OS. -- kvm-84: virtio on qcow2 broken (regression) https://bugs.launchpad.net/bugs/404394 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to kvm in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

I'm also hit by bug#448694 which was the reason for using qcow2 images in the first place. Now I'm pretty much left in the cold ... cannot use RAW or LVM ... and neither qcow2.
