That's a pretty beefy update! It's great to see the live storage migration performance improving by a very nice margin

@JamesG Thanks. I'll let @teddyastie see. I think he would be more confortable with having the card in our lab, which should be imminent now, but I won't speak for him.

@mike.potapov blktap-3.55.5-11.1.xcpng8.3 was released today in xcp-ng-testing with the fixed to avoid stalled IO. (Announce in https://xcp-ng.org/forum/post/108803). Can you give it a try?

I get out of my silence to confirm that I'm indeed working on AMD MxGPU driver and AMD iGPU passthrough issues.
I confess that I have not communicated since a while on this work, but I'm making progress and I'm very close to publish a call to testing PoC packages that should improve the iGPU passthrough situation.

@pandusen said:

But I would in any case where PCI passthrough for edge cases like the GPU marked kind of is, is not a requirement, Always recommend XCP-ng over the others.

Thanks for that :).

There's no problem to state faithfully what works and what doesn't with a solution, and adapt the advice to the actual needs.

I just felt compelled to react because I didn't find it entirely right to state that GPU passthrough has low priority. It's supported in general, but there are devices that come with technical challenges not fully addressed yet in Xen or in XCP-ng, and we treat that as part of the general hardware support we aim for.

Same as we work on device drivers for devices mostly found in home labs, without dismissing them as low priority.

And it's a good point to state that the needs around GPUs are growing fast due to AI, indeed.

@flakpyro Note that various important Viridian settings are not yet settable via Xen Orchestra, so you might want to confirm using xe instead.

@flakpyro These template updates only concern new "from scratch" VMs. Older VMs should not be impacted at all.

But if some of your VMs are missing Viridian settings, you may run into poor performance and/or odd Windows issues. You can correct them using the instructions documented here: https://docs.xcp-ng.org/vms/#enabling-viridian-extensions

@ovicz I was wrong, it's already in testing. So you could simply install the testing updates for that.
