    GPU passthrough issue

    Not much to to work with here, indeed, all looks good. Not sure if this line should read passthrough instead, i know it shows passthrough with my setup. [Sat Jun 20 00:01:24 2020] iommu: Default domain type: Translated In the past i noticed reordering kernel boot paramters does make a...

    Help for hardware

    Very nice specs. Much more than you need for 5 VPN connections :) Running a firewall in a vm is okay but if the VM server is in a highly sensitive area i would advise against it. Just because VM breakouts happen and if it takes the server down there is no more firewall. You could consider...

    Help for hardware

    Running with a 1700x 8 cores and 32GB of ram, a 1.13TB zfs pool built on 3 cheap ssd drives (2x sata, 1x nvme) works great, but i think 64GB or even 48GB would be just right. CPU is amazingly little in use, RAM is forced to run at 2666Mhz instead of 3200Mhz since upgrading to 32GB from 16GB...

    [SOLVED] sometimes it is just maddening

    Just one hour ago. The machine froze again. The system which rebooted fine multiple times before is now (as per usual) showing "vfio-pci ...... vgaarb: changed VGA decodes: olddecodes=io+mem, decodes=none:eek:wns=none" as the last line on the screen, strangely it reboots almost immediately on...

    [SOLVED] sometimes it is just maddening

    Ah, thanks.May i suggest to document that not-mounting bit and such ? OOPS From the page you mentioned, i missed this 3 times. The ESPs are not kept mounted during regular operation, in contrast to grub, which keeps an ESP mounted on /boot/efi. This helps to prevent filesystem corruption to...

    [SOLVED] sometimes it is just maddening

    Thanks Stoiko. I had a read again on this page now i slept a few hours. Typical as for many open source 'documentation' it is informative, not helpful. That much i could learn with 'man bootctl' and 'man systemd-boot' What has me stumped is systemd-boot works fine but the /boot/efi partition...

    [SOLVED] Install qemu-guest-agent - Debian 7 Wheezy

    also a possiblity is to enable backports on Wheezy or to check with apt-cache policy qemu-guest-agent which versions are available then install with apt install qemu-guest-agent=<versionnumberyouwanthere>

    [SOLVED] sometimes it is just maddening

    Am i correct in assuming this is simply how systemd-boot works ? The system boots fine now, except for this. bootctl status Couldn't find EFI system partition. It is recommended to mount it to /boot or /efi. Alternatively, use --path= to specify path to mount point. Even after reinstalling...

    [SOLVED] sometimes it is just maddening

    maybe i am just impatient, may i just lack common sense how on earth does one fix systemd-boot after doing upgrade-grub ? running bootctl simpy lists the partition which holds the ESP mounting this partition on /boot/efi and running bootctl again shows success still, no boot the ESP/EFI...

    [SOLVED] sometimes it is just maddening

    aaah. the sweet agony of systemd-boot. What works once, does not work again. for example module_blacklist=vfio-pci would i dare to consider systemd has somehow something to do with this time consuming event ? because yeah, i did run update-grub and that is not what i was supposed to do, huh

    [SOLVED] sometimes it is just maddening

    because i fail to understand i share my clumsly learnings with proxmox For some reason or other i wanted to explore how to configure two bridges using a single NIC. Eventually this resulted in the faint hearted decisions to set the gateway of vmbr0 to 0.0.0.0, because who knows, it might just...

    with multiple PCI devices the .conf file gets "rewritten" and the VM no longer boots

    this is no longer an issue now, i have absolutely no idea why not anymore. If it resurfaces i will update the thread. to know, i have not customized vmid.conf in any way, simply using the web interface. The only manual configurations i made were the corrections required after observing the...

    with multiple PCI devices the .conf file gets "rewritten" and the VM no longer boots

    this happens for any VM i attempt passthrough with for both GPU and Audio (same ID.x) latest VE 6.2 fully updated qm start simply states the device was allready assigned/associated, which is how i found out about this happening in the first place

    with multiple PCI devices the .conf file gets "rewritten" and the VM no longer boots

    While struggeling with PCI passthrouhg (it does work, eventually) i found something peculiar. Sometimes the VM would not boot because the PCI.id for a device was alread in use. This was because the pci-id for the vga and the audio were written as the same. So instead of 0000:17:0.0 and...

    GPU PCIe Passthrough stopped working after update

    It is demanding to get it working but i can say nothing is broken, at least not for my system. This machine is running on Proxmox VE 6.2 since about one month. GPU passthrough is quite demanding in my experience but if it works, it works very close to native speed. Staring a VM from the shell...
