[libvirt] looking again at add nested HVM to libxl

I agree that it needs to be done the right way. I am willing to help where I can but my basic knowledge of the code is badly lacking so there is no reasonable way for me to contribute in a significant way. I am ok keeping my own hacks to the code that let me work along on my projects and hope that some day this will get fixed. On 10/02/2015 10:03 AM, Daniel P.
