    @GTwannabe I assume he means using PCI passthrough for the USB port/controller so HA has direct access to that level of the hardware to circle around some USB passthrough problems. In my case this did not helped with the ConBee, but you might try it anyway and it is no problem to reboot the host which is needed to activate the PCI passthrough Another pro for switching to an IP based controller is that you can backup and migrate the VM without any problem.

    @Nevering We used to offer a “hosted Vates Stack” service, but right now we’re rethinking that and don’t have anything "official" to share just yet (though you might wanna keep an eye on our newsletter ). In the meantime, here are two easy options: Head over to our Partner Locator and use the filters to find a CSP (Cloud Service Provider) — some MSPs also offer hosted setups. Shoot us a message at partners@vates.tech or via our Contact Form, and we’ll do our best to point you in the right direction.

    @Riven, What I am not sure is how Xen arrange the CPU, is it core first followed by the SMT/HyperThread Core? or is it alternating ie RealCore, HyperThread Core.

    @2planks said in NIC not working on new HPE DL360 Gen11: Has this issue happened before? I don't remember such an issue on this hardware. Can you share the outputs of lspci -v, lsmod, dmesg, and dmidecode?

    @efny I thought it wouldn't but in fact since I have it (almost a year) I had 0 bug. It's a Core i7-1255U.

    @MJGZ51 Hi! Since 8.3 PCI passthrough is part of the XAPI and come with dedicated xe commands: xe pci-list to have the list of PCI devices and then: xe pci-disable-dom0-access uuid=<pci uuid> to hide th device from dom0 xe pci-enable-dom0-access uuid=<pci uuid> to unhide the from dom0 These are the same API calls made by XO or any XAPI clients No need to edit manually the cmdline anymore! Regards

    @nvs said in XCP-NG server crashes/reboots unexpectedly: Thanks. Unfortunately my machine doesnt have IPMI. So can I just connect a serial cable between this machine and another machine Yes though you would still need to boot using the "XCP-ng (Serial)" grub entry. (you can also add some serial console bits adding them to xen cmdline)

    @yzgulec as people have rightly said above, no hard and fast rule. But when it comes to sizing compute for mixed workloads (or unknown workloads) I have used a 1:4 (pCPU:vCPU) contention ratio. I also try and size 2GB of memory per vCPU (so 8GB RAM per pCPU), and with this 'rough guide' I find that my CPU and memory consumption scale nicely. Obviously it gets difficult when someone has a workload that needs very low CPU but high memory (e.g. I've seen a 2-core VM with 64GB memory) and conversely high CPU and low relative memory (e.g. 8-core VM with 4GB RAM)... but these are typically exceptions. Please share your decisions and build configs here, I'd be interested to see how it worked out in terms of compute:memory, costs, etc.

    @manilx It is not cheaper, but it draws about half the power when idle. When doing work the power still gets up there, they are 60-90 watt computers, which is still less than the 300 watt capable HP servers at full go. If you really stress your lab a lot, real servers are a win as they will draw less power for more performance, but if yours is like mine and it idles a lot, cutting the power is nice. I'm about 200 watts at idle with the above, and that's two labs worth. I was 400 with the single old lab system. Mounts are cheap book ends, drilled and screwed to that specific shelf, and drilled for short m4 thumbscrews to get into the VESA mount on the t740. If anyone reading this wants to duplicate, and they see HP T755 cheap enough, I recommend these because it has 6 cores / 12 threads over the t740 with 4 cores / 8 threads. Both are DDR4 sodimm and top out at 64GB. Both have a PCI 3.0 x8 (x16 slot) that takes half height cards. And if the BIOS is locked, you can write over them with a programmer and enter the data needed to function (see badcaps forum for my guide).

    @DustinB Excuse my ignorance, but I am not sure? I have two NVME drives with one being used by XCPNG/XOA. I was on xen and clicked the PCIE pass through on the host, restarted, and then black screen. I am trying to pass through the other NVME controller so I can have a truenas VM but utilizing the other NVME drive. I didn’t want one big pool because if something happens I’m not reformatting the entire thing and loose the data.

    @davx8342 That's a ton of storage, holy cow! So two pools currently, 6 Servers 31TB Shared, and then 16 servers and 400TB Shared. I honestly don't know if there is an upper or lower limit to the amount of storage supported with XOStor, I'd imagine it would work but someone else would have to confirm.

    @mohammadm said in XCP-ng 8.3 & AMD Firepro S7150x2: Too bad, so at this point we have 4/5 GPU's that are pretty much useless. Any other alternatives for GPU? When using dGPU, PCI-e passthrough to the VM itself, it does work but after a while the whole screen turn black. They have to disconnect and connect to the RDP session again to see the screen again. Looks like a screen suspend issue, have you tried to disable it ?

    @deadman2141 I'm realizing what is happening. After the memory install the system would not boot up, the bios flags the change and forces you to go through the bios setup with a hardware change. My system runs headless so I did not pick this up. After plugging a monitor in I see that message, go into bios and then through the boot sequence. This is when I notice that the system "hangs" after that statement. What I just realized is that xo lite was responding (along with pings) while the system was hung. I pass the GPU to a VM, so once dom0 gets to a certain point the GPU goes away, leaving the monitor stuck, but the system boots just fine.

    Are you on XCP-ng 8.2? Because UI to set passthrough is only possible on 8.3 up to date edit: 122 updates detected you really need to stay up to date

    Also, we might have better roles in the future to be sure other people without the right role couldn't use it.
