I created a Windows 11 and a Linux Mint VM on the same system.
The GPU is passed through to both VMs via passthrough, and the USB ports for the mouse and keyboard are routed from the host to the VM.
The GPU is an RX 6600XT installed on an Asus...
Just add iommu=pt at the end of the existing line. intel_iommu/amd_iommu is not needed.
You can check the current boot args with cat /proc/cmdline. Also see docs here.
No, as it would not make sense to disable power management for all SATA controllers. But drivers do get fixes, improvements and occasional new bugs on every new kernel version.
Please note that none of this is Proxmox specific as the PCI(e)...
Thank you.
Than I will stay with rombar=0 and try rombar=1 after the next big PVE update.
Maybe it will work than. Otherwise I hope I never get an problem with rombar=0.
And thanks again for your help with the other issue (other thread).
I...
Congratulations, your hardware works with PCI(e) passthrough which is unfortunately not that common.
Probably not. This is a common option to try enabled and/or disabled when doing PCI(e) passthrough.
Search for libata.force and then lookup...
Thank you, now I understand what I do, when setting libata.force=nolpm.
But I don't understand why deactivating the power management allows using rombar=1.
Could it be possible, that in earlier proxmox kernels the default value was...
You are right. I have the problem now.
So I opened a new thread, because I am not sure what is the better workaround .....
ASM1166 - No passthrough with rombar=1 possible - PVE9 bug?
Hello,
I want to passthrough an ASM1166 M.2.PCIe card to an VM.
It only works, if I set rombar=0.
Also it seems in PVE9 you don't have to blacklist the driver of the ASM1166, because PVE did this alone.
Is it new, that blacklisting the driver...
Hallo,
I passthrough my GPU on an AMD B550 board to an Win11 guest with PVE9.1.1.
Everything works, but in the manual is written, that i have to set "iommu=pt" to the kernel command line.
I have a zfs system. So in my opinion I have to set...
