Nested virtualization caveat
If you intend to run nested KVM/Docker
Core Idea
Nested virtualization caveat is If you intend to run nested KVM/Docker, confirm the guest sees vmx/svm flags (grep vmx /proc/cpuinfo). Some CPU types mask these flags; switch to host only when you are certain migration is irrelevant. It usually makes the most sense alongside Core count template, Changing CPU types.
