Can i install PCI-e Card on VM
- Thread starter Kujtim
- Start date
kind of both.
some of the settings need to be done on/to HOST (Proxmox) so HOST knows to provide the capability.
in the link provided, everything BEFORE section "Determine your PCI card address, and configure your VM " is for HOST
and most after the section is mixed. i.e. some command are needed for host to get the information and set the host, and some is to configure the VM.
nothing described in the WiKi is targeted for use inside VM. all of it is used to prepare the host and setup the VM for PCI pass-through,
anything you need to do inside VM would work as if you using a real hardware.
If by tuner you mean DVB-cards, I would rather recommend to solve it with LXC.
I also built a VDR with KVM and PCI passthrough, but this was sometimes very unstable and the tuners often got out of tune.
I found this howto (unfortunately in german, but I think the commands are self-explanatory and you can ask me if you have problems understanding it)

Now the VDR runs stable for months like on bare-metal hardware

I am with neonmouse on this one. the link seams very workable, and what you do is open in chrome and click on translate. it will give you a native translation.
Any luck with the pci-e (q35) configuration.. I am having the same issue and getting the error after the <VMID> is configured per the wiki for PCI (pci-e) pass through... The VM actually sees one PCI-e slot of the (dual tuner) device under hardware...
Code:
TASK ERROR: q35 machine model is not enabled at /usr/share/perl5/PVE/QemuServer.pm line 2961.ProxMox on Debian server running Ubuntu 16.4 Server VM
I wouldn't edit the server.pm on line 2961. but... Apparently when ProxMox 5.1-35 initially installed it did not detect the machine type correctly... and I can't figure out after searching for hours to find what would seem to be an elusive yet simple answer.

you can only have virtual pcie devices on the q35 machine type
the i440 does not have an pcie bus
so you have to change the machine type (not on the gui)
qm set <VMID> -machine q35
so, I have 2 pci-e slots. One has a dual gigi Ethernet card.
One channel shows up:
VM (vm-001) PCI device (hospci0) 07:00.1,pcie=1 as set in vm100.conf
The second VM (vm101) shows Hostpci0) 07:00.1,pcie=1 for pci devices. As expected.
The Dual TV Tuner does not show up under hardware in the VM (vm100) as configured.
03:00.0,pcie=1
04:00.0,pcie=1
My question is: Does PCIE=1 designate the physical slot the device is installed in?
hostpci0: 01:00.0,pcie=1

no the '01:00.0' is the physical slot, 'pcie=1' just uses that card as a pcie inside the vm (instead of pci)
I thought that was true but the duel channel DVR card shows as 03:00.0 & 04:00.0 but the dual Gigi NIC is 07:00.0 & 07:00.1?
Yet the DVR card does not show in Hardware for VM 001 but PCI Device (hostpci0) 07:00.1,pcie=1 does?

Here are the LSPCI's & configs from the VM's and the HOST... sorry it's been a bit busy this week...
No but this does... Thank you for the help!
Code:
hostpci1: 03:00.0,pcie=1
hostpci2: 04:00.0,pcie=1
