Re: Double fault panic in L2 upon v2v conversion
Thanks Richard for a fast reply. Yes, indeed, im working on a nested environment. I try to run v2v inside a VM (L1) and to create an L2 by the conversion process. And on Intel. As I wrote, it fails once in few times, mainly when there is a memory pressure on L0. Kashyap, can you please share your experience? Why should it crash during nested conversion. I'm not too familiar with libguestfs
