Title:
rootwrap daemon with libvirt/xen not working
Status in OpenStack Compute (nova):
Incomplete
Status in oslo.rootwrap:
In Progress
Bug description:
Using:
- SLE12SP1
- xen 4.7
- nova 13.1.2.dev68 (stable-mitaka tarball)
When configuring nova-compute to use the rootwrap daemon and using Xen with
libvirt as hypervisor I get the following error when booting a VM:
