Re: [Libguestfs] 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 logic - maybe you
can point for me, according to the logs, at what stage of the conversion
the failure happens.
Thanks,
Rom

Are you using nested KVM?
Kashyap (CC'd) has done a lot of testing on nested KVM on *Intel*,
never with satisfactory results. It just doesn't work very well.
On AMD is a different story -- nested KVM just works.
