Here are the current hardware specs:
AMD Ryzen 7900x
ASUS ROG STRIX 650e-e gaming Wifi
Samsung DDR5 16GB PC5-44800 * 2EA
SK hynix P31 1TB
WD Ultrastar 4TB*2EA
MSI GeForce GTX 1660 SUPER Ventus S OC D6 6GB * 2EA
I tried ESXi 8.0 for this spec, ESXi loaded just fine.
I installed Windows 10 pro here, and tried to PCIPassthrough only one graphics card, but it failed with code 43.
Parameters should not be set to hypervisor.cpuid.v0 FALSE as a workaround for Code 43, nor should SMBIOS.reflectHost = TRUE, pciPassthru0.msiEnabled = FALSE. The GTX 1660 SUPER has 4 types of PCI, so I put all 4 variables in msiEnabled.
I added pciPassthru.use64bitMMIO=TRUE as a parameter, but it failed, and I set pciPassthru.64bitMMIOSizeGB = 16. (Since the graphics card memory is 6 gigabytes, 6 x 2 = 12, the closest number to the square of 2 is 16, so I set it to 16 .)
I also have a 5900x system running (x570), this system has a GTX 1060 3GB, and on this system the ESXi works fine, so the PCIPassthrough is fine. After installing this graphics card on a 7900x system, I tried it, but the same code 43 comes out.
After that, I gave up on the GeForce graphics card and tried with the Radeon 5700XT, but the same code 43 error occurs.
I thought it was a bug in ESXi 8.0, uninstalled 8.0, tried again with 7.0U3 and it failed the same.
I confirmed that the mainboard SVM is enabled, I also enabled the address decoding option of 4GB or more in PCI, I tried enabling and disabling it anyway, although it is not a SR-IOV supported graphics card, I also enabled PCI ARI Support, enabled ACS, and enabled IOMMU. I did it. TPM doesn’t seem to matter much, but I disabled it, but all failed. BIOS has been updated to the latest version.
The only unusual symptom is that if you change the Resize BAR to OFF, and PCIPassthrough the GeForce graphics card to the virtual computer, the same symptom, but Radeon boots normally once.
However, when I try to restart the Radeon virtual machine after shutting it down, I get a DevicePowerOn error and the virtual machine cannot be turned on. In order to run the virtual machine again, the entire ESXi system must be rebooted to turn it back on, but even after turning it back on, the symptoms are the same.
When I installed Proxmox and tried it, I was able to PCIPassthrough normally in Proxmox. I expected it to be a hardware problem, but it seems to be a software problem. Does anyone else have the same symptoms?
