Dear PSI Openstack Users, 

We (PSI team) want to identify teams requiring nested virtualization to be enabled in PSI Openstack platform. We are preparing steps to disable nested virtualization for everyone by default, however, understand that some teams have a business it and such a change might drastically disturb your workflows and our aim to minimize the impact with your help.

What are we doing:

Identification of the teams/projects that require nested virt and their respective flavors. Once teams have been identified nested virtualization will be enabled only for required flavors and be disabled for others. 

What should I/you do:

Please let us know if your team (tenant) requires nested virtualization by responding to this email with the name of the tenant, and the flavors.

Also, please pass this message to teams using PSI Openstack platform if they are going to be impacted.

What will be the impact:

After the changes are applied teams requiring nested virtualization will need to use special flavors which will only be visible to the teams/projects that have a business need for it and have contacted us with the details.

If the details are not provided now a ticket has to be created with PnT DevOps (help.redhat.com) to get your tenant & flavor enabled.

Why are we taking this measure: 

Nested Virt is still in tech preview on RHEL, not fully supported on the platform. Lately, this feature has been a source of hard to debug problems in PSI OpenStack platform which is affecting all the users. 

When will the change happen: 

Please respond to this email asap, not later than 21st Aug. 

We are planning to disable nested virtualization on the platform during our next maintenance, tentative: 24th Aug 2019.

If you have any concerns with this, please comment on this JIRA: https://projects.engineering.redhat.com/browse/PSI-7978
