you can get the solution here https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/12106 in summary, just get the i915_vbt from host (before passthrough activated) copy it the VM guest, and load it from there. ready through my post in gitlab then you should know how to do.

for my experience, high IO delay only occur when intensive read write happen to HDD (but this can be solved if passthrough the SATA controller to VM).

This is just to share, if you are using intel iGPU passthrough to a Linux VM, you might encounter a problem that no HDMI output if you upgrade your Linux VM to kernel 6.10 onward. the solution will be here: https://bugzilla.kernel.org/show_bug.cgi?id=219193 i have Alderlake iGPU passthrough to...

set the Display to none in VM hardware tab. i have 3 passthrough working correctly. 2 nvidia and 1 intel igpu.

a checkbox to allow enable or disable the device, this will allow quick change without to add PCI or remove PCI in testing environment. appreciate if this can be considered.

ok, disabled secure boot in BIOS will still allow proxmox host to boot. no other configuration needed. i will just disable Secure Boot function.

I performed latest kernel update this morning for proxmox host, and went for host restart, now i ended up having this problem during BIOS boot up and the system shutdown immediately after this. i have secure boot enabled and what will happen if i reset secure boot? will it stop my system for...

it happen again today in the middle of the night where no one is using the server nor VM...... May 18 04:17:50 proxmox pvestatd[2081]: pbs: error fetching datastores - 500 Can't connect to 192.168.1.13:8007 (No route to host) May 18 04:18:00 proxmox pvestatd[2081]: pbs: error fetching...

the second reboot today which did not show any error: May 16 15:38:36 proxmox pvestatd[1871]: pbs: error fetching datastores - 500 Can't connect to 192.168.1.13:8007 (No route to host) May 16 15:38:43 proxmox kernel: [UFW BLOCK] IN=vmbr0 OUT= MAC=01:00:5e:00:00:01:c8:7f:54:c2:c1:30:08:00...

you m you may also share your config.

make sure you remove the Proxmox VGA adaptor, any software emulated VGA adaptor will stop VM from booting when you passthrough Hardware VGA. make sure you have VNC or NoMachine or XRDP installed so you can login.

with kernel 6.8, i having problem to run a grafana container. error code below, not sure if this related to change of apparmor, any suggestion? Starting btb_grafana_dashboard ... error ERROR: for btb_grafana_dashboard Cannot start service btb_grafana_dashboard: failed to create task for...

try nomachine, i am usign intel GPU passthrough to ubuntu, vm display set to none, gpu set to primary display. if you do not have a monitor connected then get a HDMI dummy plug. my only problem is i cannot get HW encoding to work....

intel 12400 for my case

stuck at this screen forever, reboot to previous kernel work.

this problem still exists, any solution?

perhaps the PCI ID will also change. my suggestion is you can: 1. install the proxmox on Xeon, build up all your VM. 2. install PBS on another PC, backup all you VM in PBS before your ready to switch, you can install PBS in another PC running another VM like Hyper-V or virtualbox. 3. when...
