No solution, but a similar problem has been described here: https://ask.openstack.org/en/question/112521/how-to-launch-a-vm-that-use-devvda-and-busvirtio-using-nova/. -----Original Message----- From: Danny Rotscher [mailto:danny.rotscher at tu-dresden.de] Sent: Monday, February 19, 2018 4:55 PM To: openstack at lists.openstack.org Subject: [Openstack] Newton - os update Hello, after we updated the os, we cannot create any new instance. We found out, that when ever we create a new vm, libvirt tries to start a vm with bus type iscsi instead of virtio. We also try to set the bus type in the image, but it does not work. Could anybody help me with that problem? Kind regards, Danny -------------- next part -------------- A non-text attachment was scrubbed...
