Thank you very much for your quick help on this one.
The patch resolved the issue for both migrations we were struggling on.

It is fantastic to see the teamwork and a resolution developed so quickly.
Really makes us feel confident in knowing we made the right decision with going to XCP-ng for our clients.

Thank you

We have been doing a fair bit of testing on our side with this client, and we have discovered it appears to be an ISP issue of some kind.

What we are finding is utilizing iperf utility a single TCP stream appears to be capping out around 40Mbps on a 1Gbps fiber circuit.

In iperf if we run multiple streams, each stream will be right around 40Mbps, so 4 streams we will get around 160Mbps throughput to our DR location.

Testing on the clients' secondary providers fiber circuit we run just fine.
Little outside of XCP-ng and XOA here and battling that out with our ISP

But that does lead me to a general question about replication.
Is the data mover process a single TCP stream per disk?
If so, is there any way to do a multi stream per disk?

Thanks

When speaking to our Veeam sources, we were told end of July is the target date for 13.1. That is what we are hoping for as Veeam is an important one for us.

Hot damn!!

@flakpyro
For kicks and giggles I tried what you had sent

xe vm-param-add uuid=VM_UUID param-name=platform msr-relaxed=true

And sure enough it worked!!
Not exactly sure the technical details on what setting msr-relaxed=true does but hey if it works it works
