I got the following error when backing up overnight: ERROR: Backup of VM 114 failed - PCI device '0000:15:00.0' already in use by VMID '107' Now I know why this is - just as it says, the PCI device (a GPU in this case), is already in use. However, I wonder what the recommended solution is? I...

I've found that selecting "restart" on a particular Windows 10 VM from Proxmox UI will freeze and restart the whole system. To start with I thought I selected the wrong thing, and restarted the node. However, I've found this is reproducible. The only different log I get from a normal VM restart...

I'm trying to run a Windows 10 VM clone from a template I've been using absolutely fine. When I passthrough an Nvidia GPU I get these errors in the logs: [Fri May 17 08:31:12 2024] x86/PAT: memtype_reserve failed [mem 0xf800000000-0xf801ffffff], track uncached-minus, req uncached-minus [Fri...

I have a strange Windows 10 guest issue. I don’t have any native Windows systems to just try it. When I copy a 20GB file over SMB, Windows 10 stutters - not just the mouse pointer, but animations in a running browser (for instance). I tried copying the file locally, while also running iPerf...

I just added a new node to my cluster. Usually, I have both the LVM and LVM-thin storage on the same SSD. On my new node I wanted to have a one small SSD for just proxmox root, and a second for the VM data. So what I've ended up with is: nvme0n1 259:0 0 3.6T 0 disk...

I have a 4TB disk I'd like to use for VMs/LXCs, as well as just local storage (mostly to mount to the LXCs - as a form of shared storage). Ideally I don't want to have to arbitrarily partition the drive, just dynamically allow either the VMs/LXCs use as much as they need, and the rest to be...

After upgrading from 8.0 to 8.1, I only got a couple of log lines in the console after rebooting. It stops at the message about initialising ramdisk. I therefore assumed it had hung, rebooted fine in a 6.2 kernel, and checked previous boot logs, only to find no errors. I then rebooted with the...

Host: Proxmox 8.0.4, Ryzen 5700x, 64GB Both Guest VMs: Windows 10, all latest updates. 32 GB assigned. Both with 'host' CPU type. Both same virtual SSD settings When I run one of the VMs, and let it settle down with task manage open, I see it idling as expected. Looking at 'top' on the host I...

EDIT - Fixed turning of CSM support (somehow it turned on randomly in BIOS). However, still want to understand the behaviour Original Post: I've suddenly started noticing, when booting a Windows 10 VM, that I don't see the Proxmox/Tianco core boot screen. I do however still see Windows once...

I usually run Ubuntu server in my LXC containers, but wanting to try Podman, which really only works well on a Redhat/Fedora base. Even though this is working, when I run podman commands in the LXC guest, I see two errors/warnings in the host logs: overlayfs: conflicting options...

I just upgrade my CPU from a Ryzen 5700G to a 5900X, and noticed the idle frequency rocketed from 900MHz to 2200MHz. As far as I know, on the 5700G the 900MHz was even there with default Proxmox settings, which I believe is "performance" (though I don't know where that's set). Anyway, I tried...

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...

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...

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'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.

Whenever I update, I'm always curious what the changes are in the packages. I'm especially interested in KVM/qemu changes, in case there are fixes that might improve performance. Is there an easy way to tell please? EDIT - Actually, in this specific case, I think I did eventually find it...

I'm having difficulty getting good LAN and WAN performance at the same time on a virtualised opnsense firewall. I'm unsure if it's a Realtek problem, an Proxmox/KVM problem, or a FreeBSD/OPNsense problem (or combination thereof) What I know is that if I enable CRC in the OPNsense VM, then: *...

I've noticed in both Safari and Firefox, and both macOS and Windows, the Proxmox web ui has some kind of memory leak. It starts of around 200MB, but will grow over a few days to >1GB. I like to just leave that tab pinned - is there some known fix for this? Are there any logs I can provide as...

Just to be clear, Promox 7 is working very well for me. I'm posting here because I know there's lots of Qemu experience. I'm finding using a particular tool called AquaSuite causes my Windows 10 VM to crash with VIDEO_DXGKRNL_FATAL_ERROR, but only after 10 minutes or so. It works fine...

I don't understand why my Promox server shutdown. In the logs I see the 'replication runner' over and over, until then I see things are shutting down cleanly. Thing is, I don't understand what triggered that? 103 is a Windows VM. I see some UPS messages, but UPS didn't lose power, and the...
