Subject [GitHub] cloudstack issue #1542: CLOUDSTACK-9379: Support nested virtualization at VM...
Date Wed, 28 Sep 2016 21:24:12 GMT
Github user jburwell commented on the issue:
    @rhtyd good idea to check the CPU flags.  There is a part of me that would like to see
a VM actually spin up inside a VM, but there are also many things that could go wrong that
are not related to CloudStack.  Plus, it would be slow.  Therefore, checking the CPU flags
is an excellent compromise.  
    Another thing that I see in this PR is that nested virtualization seems like a capability
that should be more generally expressed and managed in CloudStack's core abstractions.  @rhtyd
could you open a ticket to extract the aspects of this enhancement that are common across
all hypervisors that support nested virtualization?
