** Description changed:
- LXD 2.0.6 supports use of distinct sub-uid/gid for each running
- container; nova-lxd has support for this upstream in all stable and
- master branches so we should update nova-lxd in >= Xenial to support
- this feature.
+ [Impact]
+ By default, all LXD containers will run with the same subuid/subgid range, which means that if a single container is compromised, all containers on the same host are potentially compromised as well.
+
+ [Test Case]
+ deploy a nova-lxd based openstack cloud
+ boot multiple instances
+ they all share the same uid/gid mapping within a host
+
+ boot multiple instances with a flavor property of lxd:isolated
+ all containers have different uid/gid mappings within a host
+
+ [Regression Potential]
+ Minimal in nova-lxd itself; we're just adding an additional extra-spec and tweaking the container profile if the underlying LXD daemon supports the isolation feature.
+
+ [Original Bug Report]
+ LXD 2.0.6 supports use of distinct sub-uid/gid for each running container; nova-lxd has support for this upstream in all stable and master branches so we should update nova-lxd in >= Xenial to support this feature.
