How to forward PS/2 port, sound and SATA drives in Proxmox?

Question

linux

There is the following hardware on which Proxmox 5.3 is installed with a forwarded video card:
Processor - i7 8700k
Mother - ASRock Z390M Pro4
Video card - INNO3D GeForce GTX 1070 iChill X4

and if, in principle, a video card, USB ports, in principle, were thrown without any problems, then with PS / 2, integrated sound and hard drives connected to the SATA connectors of the motherboard are still ambush. Advise what to read on setting up?

конкретно мя интересует 00:1f.3

If you throw the sound as a video card, by writing in the virtual machine config for the Audio device: Intel Corporation Device a348 (rev 10):
hostpci2: 00:1f.3,
then everything works, but the web muzzle falls off for proxmox until the reboot and the network falls off in the virtual machine.
In the course of googling for sound forwarding, it turned out that the problem is that there are several devices in one group, hence the network crash ...
kvm: -device vfio-pci,host=00:1f.3: vfio error: 0000:00:1f .3: group 8 is not viable
write that it is necessary to separate them.

Yes, if you are trying to forward some pci device from a group where there are other devices, then they also need to be bound to either vfio or pci-stub, although forwarding to vm is not necessary.

but I haven't found how to do it correctly yet ¶

Answer 1

Read how everything is thrown into kvm, proxmox has nothing to do with it
