Maverick has libvirt 0.8.1 now, so support for dynamically attaching of scsi devices is deprecated. -- dynamic block storage should use virtio https://bugs.launchpad.net/bugs/588410 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to eucalyptus 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

Right, as Jamie says, any distro that includes libvirt = 0.8.1 will not work with scsi for hot attach. If upstream Eucalyptus would like to see scsi supported for hot attach, they should perhaps open (another) discussion with upstream libvirt and qemu.

Yes, I understand. I was replying to this part: As an added benefit, performance should increase significantly. This is not necessarily true, and in some cases, we have seen 10% performance degradation by moving to virtio. It will be a while until all distros move to libvirt 0.8.1. From an upstream point of view, we intend to support both options until dynamic attach for scsi is dropped from all distros that Eucalyptus runs on. -- dynamic block storage should use virtio https://bugs.launchpad.net/bugs/588410 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to eucalyptus 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 588410] Re: dynamic block storage should use virtio
Just as a warning, we have seen cases where enabling virtio for disks actually degrades performance when compared to scsi for dynamically attached disks. We will be enabling virtio for the next release, but it important (from the upstream's point of view) that it be an option. -- dynamic block storage should use virtio https://bugs.launchpad.net/bugs/588410 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to eucalyptus 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

Dave, Could you go ahead an prepare a Eucalyptus upload for Maverick with this patch, and ask for sponsorship? Scott or I should be able to help with that.

Dustin et al, Just FYI, we're definitely adding virtio support, for both network and disk, in the next release (Ye is working on it right now). It will be an option that can be turned on by default on Ubuntu.

I'm attaching a patch that I tested, which generally seems to work. ebs attached volumes are then attached as virtio devices. ** Patch added: patch for using virtio for ebs devices http://launchpadlibrarian.net/49623427/ebs-virtio-debdiff.diff -- dynamic block storage should use virtio https://bugs.launchpad.net/bugs/588410 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to eucalyptus 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
