Enable VT-d(Intel Virtualization Technology for Directed I/O), for IOMMU(Input Output Memory Management Unit) services, and SR-IOV (Single Root IO Virtualization), a technology that allows a physical PCIe device to present itself multiple times through the PCIe bus, in motherboard BIOS in Chipset, e.g. ASRock Z790 Riptide WiFi.
Enable SR-IOV for Mellonax network adapter e.g. Mellanox ConnectX-4 MCX455A-ECAT PCIe x16 3.0 100GBe VPI EDR IB in the same motherboard BIOS.

Download Linux i915 driver with SR-IOV support for Linux kernel:
Add a PCI device for Ubuntu VM, and choose one Virtual GPU; Enable Primary GPU and PCI Express in options; Choose none in Display and host in Processors options:
Setup remote desktop connection to Ubuntu:
1 2 3 4 5
root@nucleus:~# apt install ubuntu-desktop
root@nucleus:~# apt install xrdp
root@nucleus:~# systemctl enable xrdp
Fix Remote Desktop audio over HDMI issue with the script, enable the sound redirection:
1
terrence@nucleus:~$ ./xrdp-installer-1.5.1.sh -s
then reboot VM.
Now Audio device becomes xrdp input / output.
Windows Server 2022
Windows Server 2022 is similar to Windows 11 setup in Proxmox. A few issues like GPU:
just disable GPU then enable it, it will work correctly.
And no sound after installation, but can enable Windows Audio Service and choose Remote Audio:
then audio over HDMI to remote desktop can work.
In addition, can setup User Auto Logon after Windows Server 2022 startup. And check Windows license by running:
1
PS C:\Users\Administrator> slmgr -dlv
Now can remote desktop access Ubuntu, Windows 11 and Windows Server 2022 VMs both run in Proxmox:
