Hi,
Has this been resolved? Is anyone working on this issue?
I had traced down the effect and found a possible solution, see
https://bugs.launchpad.net/nova/+bug/1560965
If you're just trying to start via Horizon, changing
/srv/www/openstack-dashboard/openstack_dashboard/dashboards/project/instances/workflows/create_instance.py ought to fix this for
you:

I'm not aware which side effects this change can have. I started a
similar thread in the mailing list this week

Zitat von "Benjamin, Arputham" <[email protected]>:
Launch of an instance from a bootable volume fails on Xen env.
The root cause of this issue is that Nova is mapping the disk_dev
/disk_bus to vda/virtio
instead of xvda/xen. (Below is the session output showing the launch error)
Has this been resolved? Is anyone working on this issue?
Thanks,
Benjamin
