Abend zusammen, Wie „sicher“ ist eigentlich PCI-Passthrough? Ich bin aktuell am überlegen folgende Konstellation zu bauen: 1 Host mit einer zusätzlichen Netzwerkkarte. Die Karte hat 2x 10G. Die beiden Ports sollen per PCI-Passthrough an eine Virtuelle OPNsense weiter gereicht werden. Hinter...

Hi all, I tried to PCI passthrough a SATA controller (not the onboard one) to my vm and found a significant performance drop, the write speed was dropped to 8x MB/s. But when I mount it directly on PVE, the writing speed came back to normal. Can someone help me on this issue? Thank you! Here...

Hi all, I read a lot of reports here that GPU passthrough or RAID systems do not work any more with PVE 7.2 and kernel 5.15 when using intel_iommu=on and the advice is to go back to kernel 5.13 or turn intel_iommu=off - iI understood all the posts correctly. i have however not seen a posting...
