Well, it's been more than a week now and have only good news to report with running 7.6.

In fact, I'm rather stunned - as CPU usage / Load logging clearly demonstrates even significant performance gains on my my HomeLab production system (an i5 7200 Intel NUC-Like system with 6 Intel NICs & 24GB RAM / 500GB Samsung EVO SSD).

Running 4 Linux VMs / a BSD VM / a Windows10 VM on XCP-NG 7.5 - CPU perf was averaging around 25% & Load was around 0.4-5 average when under light load.

Now, running all those VMs on 7.6, CPU perf average has dropped to 10% and Load averages have also dropped to 0.1 - 0.15 under the same VM load as before.

My two other XCP-NG - a Disaster Recovery box and a Test Bed (a laptop from 2009) also appear to have realised similar performance gains as well.

I didn't see any mention of "performance gains" in this maintenance release, but I'm amazed and very impressed.

I did do complete fresh Installs on my production system & DR Box, and only did an upgrade on my Test Bed laptop. All 3 migrations to 7.6 went without a hitch.

Well done contributors and builders - well done indeed!

First off, thanks to @Aimdev and @fjen for providing a good write up of the steps taken to get USB passthrough to work.

I followed them all pretty much with out any difficulty and with no errors on anything for a Broadcom Bluetooth USB card (Broadcom Corp._BCM2045B) that's built into my laptop I'd like to pass through to a Linux VM.

And I get all the way up to where the USB device is correctly presented in the XCP-ng Centre application, but the device doesn't [seem to] appear at the OS level in dmesg | grep usbcore or lusb outputs in my guest OS VM.

However, since I didn't any failure to start the vm or other errors, I had not executed the final command: xe vm-param-set uuid=<VM UUID> platform:device-model=qemu-upstream-compat

But since the Broadcom chip still didn't appear in the guest Linux VM, I shutdown the VM and then executed the above command with the VM UUID.

But after a restart, the VM still doesn't see the Broadcom USB device.

Any idea what could be up or suggestions where I need to dig?

@borzel Okay, I'll wait. I just was very much wanting to help test them. This whole system is a 'test system' for me to play with.

Enjoy your vacation.

@borzel said in [Test] XCP-ng 7.5.0 Windows PV-Drivers and Management Agent:

currently we don't have them

I'm confused now. I thought that's what I was installing....I am running XCP-ng 7.5 here. I haven't downloaded anything from Citrix at all.

Edited to add: Okay, I just went back and re-installed Windows10 from scratch and see I end up automatically with XenServer PV drivers. How do I get the XCP-ng pre-release PV drivers installed then?

@borzel Oh crap, how did I manage that?

Not a problem tho - I have a Snapshot image I can revert this too before the installation of the PV drivers.

Would you be so kind as to direct me to the latest and greatest and proper PV drivers I should be using & I'll revert snapshots and install those.

@borzel

Like this? Or am I still missing something?

@borzel

Okay, posting from a different VM works. Odd that.

Furthermore, although this would bork out with installation errors, running the Installer against offers me the option to Repair the installation, which it claims to do successfully. But upon reboot, it crashes on startup with a BSOD.

A couple of times, I tried to let Windows Repair the damage after it would BSOD, but it would always give up saying it was irreparable.

I screen captured ALL of the Installer logs (lots of screen captures). Rather than posting all 20 or so, is there a particular Installer Log file you'd like to see first?
