Thinking about it the IDE emulation may be the problem. If I remember it well the disk timeout messages on the guest had 'ata' in it. This is not really my cup of tea but I know that ATA and IDE are related.
But please remember that my problem is only one example of what can happen when using CFQ on servers. For lots of common server tasks using CFQ is not recommended, so I still think this is a valid bug report. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1008400 Title: Ubuntu server uses CFQ scheduler instead of deadline To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1008400/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
