Hi I'm keen to try resizable bar in a Windows 10 guest with passed-through GPU. So far as I know this commit gets it into EDK2 (which if I understand correctly is the source for OVMF BIOS in Promox/QEMU): https://github.com/tianocore/edk2/pull/1351 It looks like Proxmox 6.4 has 2.2020 from...

I think I may have fixed it. In my case I have several devices attached by PCIe, two on the motherboard, and three on a bifurcator: On the motherboard: x4 PCIe 3.0 Samsung 970 Evo Plus x4 PCIe 4.0 WD SN850 On the bifurcator in x8x4x4 mode (all PCIe 3.0): x8 RTX 3080 (with 2x6-pin...

I'm backing up two Windows 10 VMs, both from the same linked Windows VM clone, and both quite recent. Both are linked clones of the same template, and have only been setup for a few days. I'm taking both backups using the same ZSTD / snapshot settings, and both while the VMs are shut down (so...

I was playing a game on a Windows VM, and it suddenly paused. I checked the Proxmox logs, and saw this: [268690.209099] nvme nvme0: controller is down; will reset: CSTS=0xffffffff, PCI_STATUS=0x10 [268690.289109] nvme 0000:01:00.0: enabling device (0000 -> 0002) [268690.289234] nvme nvme0...

I've got linked clones working for both Linux and Windows 10 guests. However, I'm concerned that say one or two years down the line the cumulative updates in the linked clones (that aren't in the base image) will mean a significant performance penalty. Or does it just mean extra storage? Is...

Generally with my Ryzen 3900x I'd use 'host-passthrough', but in Proxmox I only see 'host'. When I used 'host' in Proxmox, my Windows 10 VM crashed. It works with EPYC IBPB however. Which should I use?

Coming from virt-manager I'm used to setting threads as well as cores. So for my 3900x, I sometimes use 1 cpu, 12 cores, 2 threads. However, there doesn't seem to be an option to do that in Proxmox.

May I ask what the rationale is for this please?

I setup a connection to my NAS to store ISOs, and I was surprised to see Proxmox insists on its own directory path on my NAS, rather than me being able to choose. I know I could setup a symlink from template/iso myself, but there's still an odd looking 'template' dir in my root.

One thing leaps out here - 30x “write amplification”. Do you have any more info on that, or why exactly this is please? regarding Proxmox itself, for home use I guess limiting logging might be a good idea (why write so many logs you generally never need to look at), or writing logs to tmpfs...

May I ask if you got this working please? I recently noticed 4k random reads/writes are 25% slower through a VM, and AVIC has been mentioned as a solution.

I have a WD SN850 that shows 3700MB/s random reads and 3000MB/s random writes. I'm using a 64GB LVM partition (no snapshots) on that drive within a Windows VM, and the same test shows only 540MB/s read and 530MB/s write. I've tried using the 'IO thread' option, that made a very small...

Sorry by not working, I mean not working in Proxmox, not physically broken. The newer it is, the more likely. You might see something in dmesg - in my case it was essentially an inherent problem with my NIC model that’s only worked around in newer kernels. Difficult to determine, because it...

What’s actually in the Proxmox-specific kernel? So far as I can tell from the repo it’s just a few patches like ACS. if we don’t need those patches, are we ok to use Debian buster kernel (support notwithstanding)?

Are you sure your NIC is working? I spent ages on a similar issue only to find the NIC on my motherboard had a quirk not fixed or backported to kernel 5.4, which is not on the Proxmox 6.3 ISO. If you have an alternative connection you can update and get kernel 5.11 automatically now. Otherwise...

If it’s all in /var/log can always redirect that to a slower and more robust disk.

I was thinking about this just the other day. Either this, or a cut-down product. I’m essentially using Proxmox as a really good web UI alternative to virt manager, for literally just three or four VMs on a single machine. I don’t use Ceph or multiple nodes, or VM migration.

Update - through sheer brute force fiddling with VM properties, the issue I'm facing seems to be some combination of 'balloon memory' setting in KVM, and passing through GPUs separately. These things work: Single VM with balloon memory on, and either or both GPUs passed-through Two VMs with...

I have Proxmox 6.3 and trying to start a Linux VM. I see the following logs - then the whole PC crashes! I'm not sure how to get more verbose logs, or to see what's happening with 'query-proxmox-support', and why that would be timing out? Mar 26 07:27:46 pve systemd[1]: Started 100.scope. Mar...
