I thought that should only affect the performance on the virtual drive though, not the passed-though drive?

Ah, sorry, I'm confusing things - actually I tried three ways: 1) Windows host 2) Proxmox host, with tested drive a vfio scsi drive on the nvme I'm interested in (no caching) 3) Proxmox host, with nvme drive passed through. In case 1 and 2, 4k random writes with 32 queue depth are good. In the...

Yes, identical VM - the OS itself is running off a virtual disk.

Just one socket - It's a Ryzen 3900x 1 socket/12 core/24 thread. I set as 1 socket, 12 threads, 'host' cpu type for VM.

I have a Firecuda 530 1TB, which can get ~660 MB/s on 4k random writes with a 32 queue depth. However, I'm only seeing 260 when the whole disk is passed through to a windows VM. All other figures (including read 4k random, and sequential) are fine. The VM itself has 12 threads and plenty of...

Actually, I'm getting confused between what 19-6-pve suffix means vs 19-15 suffix?

Per title, I'm trying to build the kernel with a quirk patch enabled. root@pve:~/sources/pve-kernel# uname -a Linux pve 5.13.19-6-pve #1 SMP PVE 5.13.19-15 (Tue, 29 Mar 2022 15:59:50 +0200) x86_64 GNU/Linux I've thus checked out...

Thanks @fabian That's something to work with.

Thanks again. This is probably venturing into Qemu territory that I should probably find another forum to ask. However, if the VM is "started...in a paused state", and "just reading the full data stored for the guest image", what is Qemu process doing differently that couldn't be achieved just...

Thanks @fabian Do you have any inkling then please, what might contribute to a NVMe or PCI problem either while running the VM, or just backing it up? Does the backup process use the virtio scsi driver? Could there be low level qemu/kvm issues there, or any verbose logging or settings that...

I'm having an issue with my nvme controller going offline https://forum.proxmox.com/threads/proxmox-just-died-with-nvme-nvme0-controller-is-down-will-reset-csts-0xffffffff-pci_status-0x10.88604/page-2#post-471159 As you'll see in that thread, there are lots of possible causes, but I've now...

I check https://git.proxmox.com/?p=pve-kernel.git;a=summary for changes, and there's only been two changes since this thread. One's for an network controller, the other for NFS.

I've seen a number of threads now about issues with Nvidia GPU passthrough after upgrading to Proxmox 7.2 and/or kernel 5.15. There's a few workarounds, with mixed reports about what works, but I'm wondering if it's likely to be fixed properly soon, or whether I should just go ahead and update now.

I'm wondering if any of these fixes are likely to be incorporated into Proxmox, as currently I'm holding off upgrading from 7.1 to 7.2

Side note - what mini pc? What NICs does it have? Just to warn if they are not Intel ones, you’re going to have problems with pfsense throughput otherwise.

I think I may be near the end of the journey https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/focal/commit/?id=47add9f75714fabd3702dca0e5899a56d2f3ee2f Essentially, it seems some deep power states are not working on some SSDs on Linux, and there's a quirk patch. That said...

Looking into this further, I think it might just be an issue with power states: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1705748 https://bugzilla.kernel.org/show_bug.cgi?id=195039...

Ok, I got something after building the ancient it87 out-of-tree driver: root@pve:~/drivers/it87-it8688E# sensors it8688-isa-0a40 Adapter: ISA adapter in0: 276.00 mV (min = +0.00 V, max = +3.06 V) in1: 1.99 V (min = +0.00 V, max = +3.06 V) in2: 1.99 V (min =...

@leesteken - would you believe it, I've asked the same question about sensors before on the x570 (I since moved to b550 to avoid chipset fans) https://github.com/lm-sensors/lm-sensors/issues/154#issuecomment-650662163 Anyway, I think that'll work. I can then monitor voltages and see if they...
