Hi Everyone,

 

I have a use case within the business where a team wants to be able to leverage nested virtualization.

I’m currently running some test within our test environment but wanted to understand if there are implications from nested virtualization such as:

  1. Does having VMs within cpu_passthru=true have any performance impact on that node / cluster
  2. Live migration considerations
  3. Replication considerations

 

I think its pinned to the host so you can’t do any live migrations

definitely you do not want to try nested virtualization in your production environment.

you will be able to do the live migration /replication within the scope of your nested environment.

Hi Jamali,

We are only testing it within our test environment at the moment.

Can you help me better understand the thought process behind the recommendation not to do this in production or what this a general statement of “Don’t test this in production”

Hi Jarrod, 

 

You can test on the production cluster. That is no problem. As long as you understand that replication and live migration is not working. Then it is no problem. So the virtual machine, which had nested virt turned on,  will be shutdown during LCM operations (for example)
