I came across with this while I was building a test environment for my testings on Dell R610 server. First of all I was doing my own research before I go and build the VMs straight away. I was read and scratching tons of blog posts and I found below recommendations for the nested virtualization.
- Nested 32 bit VMs – Intel VT-x or AMD-V is required
- Nested 64 bit VMs – Intel EPT or AMD RVI is required
Copy and Paste the below url on your browser and you can search “nestedHVSupported” , note the boolean value right next to the feature. Value should be true if it truly supports to the above Intel and AMD options.
