@FMOTrust I had this issue as well on a Slave host in my test environment. I was able to do Network Reset from xsconsole, but then after the Host rebooted to finish the reset, the Host reverted back to not having/seeing the Mgmt network, and...like you, I couldn't see any NICs either. Since this was for testing, and I had no VMs on it, I just reinstalled XCP. I think there's a way to reset XCP I saw in another Forums post by removing the Local SR? Olivier shared that in the post..but I don't remember what post it was. Not sure if this is a test or prod Host/environment for you...but if you can, unless someone from the Vates team comments, I think all that can be done is reinstall.
