@conitrade-as Yes, fixed. Thx! The issue on this VM was we were installing as non-admin. All others were admin by default. Good catch

@kratos said: This may not be best practice. in a two hosts pool, if your replicated VMs live on the Master, and it's gone, you won't be able to start the replicated VMs you will first need to transition slave to master indeed CR is better to another pool

But thank you for your time all the same.

@User-cxs PV drivers / Xen Tools installed? Was the system rebooted cleanly after enabling nested virtualization/Hyper-V?

@rzr Hi. Thank you very much. I will be setting up a new server within the next 2 weeks and will definitely test it. Then I will give you feedback! Thank you again for picking it up!

@Pilow We tried that as well, same problem Also tried with a VM on the same newtork, just another VLAN, and we're seeing the same thing. At first we figured it was because one of the xcp-ng's was on a remote site which is connected through an IPSEC VPN, but that wasn't the case.
