USE_VIRTIO_DISK config option ignored for EBS volumes

[Kiall Mac Innes]

Ubuntu 10.10 / eucalyptus-2.0+bzr1241-0ubuntu4 / amd64

After setting USE_VIRTIO_DISK="1" (the default actually..) in /etc/eucalyptus/eucalyptus.conf and performing a clean restart virtio is not used while attaching an EBS volume.

I discovered this due to a related bug preventing non-virtio volumes from attaching correcting until after the instance reboots (I'll file this one as soon as I find out if its in kvm or ecua!)

I made a *very* dirty hack to node/handlers_kvm.c on L452 / L459 to ensure bus='virtio' was added to the XML .. suddenly it works :) providing an /dev/vda (I'd prefer the device name I specified .. but one step at a time!)

And .. As always with filing a bug. I just noticed a mistake on my part! L436 of node/handlers_kvm.c forces the use of a non-virtio mount thanks to me specifying a sdX device name rather than vdX .. I'll dig around for the close button!

Thank you for taking the time to report this bug and helping to make Ubuntu better.

Does this mean this bug should be marked as Invalid?
