Re: [PVE-User] windows remote desktop services as VM on proxmox

["Daniel Plominski" <dpl@ass.de>]

Hello Daniel Bayerdorffer,

Long story briefly explained on the example of an AMD server with NVIDIA 
graphics card (on Proxmox 6.4 / 7):

1. activate IOMMU, deactivate framebuffer

root@assg25:~# cat /etc/kernel/cmdline
root=ZFS=rpool/ROOT/pve-1 boot=zfs amd_iommu=on iommu=pt video=efifb:off
root@assg25:~#
root@assg25:~# update-initramfs -u -k all

2. deactivate (nativ) Kerneldrivers

root@assg25:~# cat /etc/modprobe.d/blacklist.conf
blacklist radeon
blacklist nouveau
blacklist nvidia
blacklist nvidiafb
blacklist snd_hda_intel
root@assg25:~#

3. load vfio drivers

root@assg25:~# cat /etc/modules
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

vfio
vfio_iommu_type1
vfio_pci
vfio_virqfd

# EOF
root@assg25:~#

4. search for the appropriate graphics card entry

root@assg25:~#
root@assg25:~# lspci -v > /tmp/GPU_INFO
root@assg25:~#
root@assg25:~# grep -A 30 "Quadro P1000" /tmp/GPU_INFO

root@assg25:~# lspci -n -s 27:00
27:00.0 0300: 10de:1cb1 (rev a1)
27:00.1 0403: 10de:0fb9 (rev a1)
root@assg25:~#

5. configure vfio.conf

root@assg25:~# cat /etc/modprobe.d/vfio.conf
options vfio-pci ids=10de:1cb1,10de:0fb9 disable_vga=1
root@assg25:~#

6. host reboot

sync
update-initramfs -u -k all
proxmox-boot-tool refresh
sync; reboot

7. create a windows vm in ovmf (uefi) mode, machine type: pc-q35-5.2, 
cpu with hidden and hv-vendor-id flag and gpu (hostpci) passthrough

root@assg25:/etc/pve/qemu-server# cat 216.conf
#
#term41gpu
#
#GPU - PCIe 27%3A00
#
agent: 1,type=virtio
balloon: 0
bios: ovmf
boot: order=virtio0;net0
cores: 12
cpu: host,hidden=1,hv-vendor-id=proxmox
efidisk0: local-zfs:vm-216-disk-1,size=1M
hostpci0: 27:00,pcie=1
machine: pc-q35-5.2
memory: 73728
name: term41gpu
net0: virtio=XX:XX:XX:XX:XX:XX,bridge=vmbr107,firewall=1
numa: 1
ostype: win10
scsihw: virtio-scsi-single
smbios1: uuid=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX
sockets: 2
startup: order=116
virtio0: local-zfs:vm-216-disk-0,iothread=1,size=256G
vmgenid: XXXXXXX-XXXX-XXXX-XXXXXXXXXXXX
root@assg25:/etc/pve/qemu-server#

8. install the windows server drivers from nvidia

9. activate the necessary RemoteFX settings using the active-directory 
group policies (or the local ones)
