@lavamind good. I was following a different thread of the bug. Back to try iscsi again.

I been using xenserver in a hobbiest role for years. I too was disappointed in the removal of features as I was looking forward to using some, such as gpu pass through. I just recently installed xcp-ng over xs7.4 and stared to play with it with XO. While my servers are server grade but storage is still not up there. I tried using iscsi to freenas over 10gig in xs but tripped over that iscsi bug in xs and hanging up on reboot. So I went back to local storage using software raid. I look forward in contribute to the community to improve xcp-ng.
