Hello everyone, for a week now I have been trying to solve a problem on a server running proxmox 7.3 ! On December 6th, I found my server completely crashed in Kernel panic, that day I only managed to take one screenshot in IMPI. Since then, the server rebooted once every 24 hours more or less...

Hi all, As the title states, I have a 2nd NIC on my HP ProLiant DL360p Gen8 server (The first NIC is a quad 1Gbps NIC). Upon getting my hands on the NIC, I installed Proxmox 7.1-7 and ran the following script I wrote: #!/bin/bash # Configure apt sources and install necessary packages...

Thank you leesteken. VT-d is for sure enabled. The output of cat /proc/cmdline is: BOOT_IMAGE=/boot/vmlinuz-5.15.74-1-pve root=/dev/mapper/pve-root ro quiet intel_iommu=on iommu=pt And the output of efibootmgr -v is: BootCurrent: 0000 Timeout: 1 seconds BootOrder...

...working fine before the update. Now they won't start and I get the following error: TASK ERROR: cannot prepare PCI pass-through, IOMMU not present When I start the VM from command line, I get the following message: cannot prepare PCI pass-through, IOMMU not present My /etc/default/grub is...

bonjour, Je sollicite votre aide car suite à la mise à jour de proxmox vers la version 7.2.11, la carte réseau de ma vm windows 11 ne fonctionne plus. Je voulais initialement des fenêtres que j'avais migrées de 22h1 à 22h2 mais après réinstallation complète toujours le même problème. donc je...

Hi I'm new to promox and virtualization. I followed the guides that I could find for pcie passthrough and I don't seem to make it to work. I get the bellow: [ 0.012286] ACPI: DMAR 0x00000000C9EC9000 0000A8 (v01 INTEL SKL 00000001 INTL 00000001) [ 0.012324] ACPI: Reserving DMAR...

The kernel version that came with early 7.2 had Intel IOMMU enabled by default, but this change (compared to earlier kernels) was reverted because it caused problems on some systems. Add intel_iommu=on to your kernel paramters (see the manual) and it will probably work well again.

...seems fine other than my TrueNAS VM will not start. I'm getting this error - TASK ERROR: cannot prepare PCI pass-through, IOMMU not present TrueNAS has been running fine prior to the update. Edit, I'm passing through SAS3008 controller. For the four 4TB hard drives. After reboot, the...

...GPU passthrough stopped working all together. When I try to start the VM, I get an error that says cannot prepare PCI pass-through, IOMMU not present and the output of dmesg | grep -e DMAR -e IOMMU -e AMD-Vi is [ 0.014582] ACPI: DMAR 0x000000007BB87000 000088 (v02 INTEL EDK2 00000002...

Hi all, you're my last hope: I have a few HP-branded Mellanox NICs (2 ConnectX-2 and this ConnectX-3). For the past two weeks I tried to make passthrough work, to no avail. I mainly want this in pfSense, but it doesn't work at all. The NICs are all recognized by the host OS, but as soon as I...

...of proxmox (kernel...), I get now the following error when trying to start the VM : TASK ERROR: cannot prepare PCI pass-through, IOMMU not present I tried to follow again this page, https://esfr.atossa.fr:8006/pve-docs/chapter-qm.html#qm_pci_passthrough_vm_config, but when after reboot, I...

I am at a loss on this one. HELP! I have 2 GPU in the system, an AMD RX580 that passes through no problem to Win 10 and a second Nvidia 1660Ti that I can not get to work in a separate Win 11 VM. I use proxmox-boot-tool and have tried pinning kernel 5.15.39-4-pve in addition to using the 5.18.19...

It worked for 1 time, I just restarted the proxmox server and after that I can't start the virtual machine. The card is in an isolated group and "initcall_blacklist=sysfb_init" is already set

Blacklisting prevents the driver from being used but other stuff might still use it like simplefb. Make sure the GPU is in a separate IOMMU group, but if this is the only one and it is in the first PCIe x16 slot then it should be (unless your BIOS breaks passthrough, which is known to happen...

...fire up, and everything looks good. I immediately try and assign the GPU to my VM, however get some errors regarding 'TASK ERROR: IOMMU not present'. I dive down the rabbit hole of PCI Passthrough, following the guides outlined here...

Dear @leesteken Many thanks for your hints that would probably solve the problem but meanwhile, and since the VM was defined to boot on start but nevertheless that took some seconds, I was able to ssh Proxmox just after the boot and check its .conf file: boot: order=scsi0;ide2;net0 cores: 2...

I believe there was a report opened against Ubuntu's kernel on their bugtracker but I can't seem to locate it anymore (or to be more specific, it seems to lead to 404). Not aware of any other reports of this issue and I'm not really in position to perform bisect to find offending change. One...

Hello, my Proxmox Server was running for years and always the PCI pass-through worked like a charm. Yesterday night I did a reboot and today I recognized my fileserver (the vm with the passed through PCI) did not start. I did a journal log but I will not be smarter with it. May I ask you for...
