Question about virtualization...

[jagdtigger]

Hi all.

 

So to cut to the chase is there a way to pass over everything in a PC to a VM except the network card? I want to run win7 on a newer machine but obviously its not possible without drivers... (I only have experience with debian and distros based on it.)

 

Thanks in advance .

Depending on that kind of VM your using, you can download on their site a driver package for the OS you're using and install those to use the virtual hardware like GPU, USB and Network.

 

I know that VirtualBox has a passthrough function for USB but Network has to be installed seperately because it needs to handle dhcp and such

Yeah i know, but the problem here is that i want to pass over everything including the igp, all usb etc... The only virtual HW gonna be the NIC since i need to reach the host OS somehow...

It's not straightforward, and it is highly dependent on which VM you use, but basically, start here:

NIC is handled natively...that will be the least of your issues

[FastRDust]

How about unraid then?

[Anghammarad]

you will ever need a second gpu... the virtualization platform will always need a own one...

[jagdtigger]

Its a intel nuc so no chance of getting a second gpu in it...

 

@FastRDust

I wont buy that just for this .

 

/EDIT

Okay, all virtualization related stuff is enabled in UEFI bot no output for 'dmesg | grep -e "Directed I/O" ', fresh headless debian install.

Little update, got the system to finally load vfio-pci for igp and sound. Now i have to deal with usb...

Its in a separate group so it should work but its refusing to cooperate. I went and blacklisted xhci_hcd then update-initramfs -u but still loads that module and not vfio-pci....

 

/EDIT

Okay, forced usb to vfio-pci manually:

root@intelnuc:/home/jagdtigger# echo "0000:00:15.0" > /sys/bus/pci/devices/0000:00:15.0/driver/unbind
root@intelnuc:/home/jagdtigger# echo 0x8086 0x2067 > /sys/bus/pci/drivers/vfio-pci/new_id

Then tried to fire up the VM:

root@intelnuc:/home/jagdtigger# ./win7_vm
cat: /etc/vfio-pci.cfg: No such file or directory
qemu-system-x86_64: -device vfio-pci,host=00:02.0,multifunction=on: Failed to mmap 0000:00:02.0 BAR 2. Performance may be slow
qemu-system-x86_64: -device vfio-pci,host=0000:00:02.0,bus=pci.0,addr=02.0: Bus 'pci.0' not found
./win7_vm: line 52: -drive: command not found

I mean technically, but if you're going to install drivers and set up in a VM to then DHD it to a new desktop.....  why not just use VM passthrough or just set up a new desktop?  Seems kinda like a waste of time.

That is the issue, there are no drivers for win7 in case of new machines.....

 

I just hit a brick wall with a error that says the IGP cant work in legacy mode because xy pci address is already taken...

mThen you're out of PCI lanes?

Maybe, its a intel nuc(6CAYH) so IDK...

Unless its a Skull or Hades, I'd say you're out of lanes.

Well then im out of luck, its just a bottom grade nuc with a celeron.

[Aremis]

Big memes bro.

[cretsiah]

dont know if your still working on this idea, but the only solution i could think of that might work, comes from when grub4dos was a thing and qemu. 

 

but i cant remember exactly how the guy actually sets it up, its been awhile.

your win 7 may still have issues if its not a fresh install (even to a VHdd image) because its not the same hardware it remembers.

 

i remember something about in the grub boot lines you forced it to look into the VHDD image as start of drive, so it would start the virtual image as though it was the real hard drive, just not sure about the network card.

 

id have a look here to see if there is a way

https://qemu.weilnetz.de/doc/qemu-doc.html (on my computer it shows in english).

[jagdtigger]

I given up on it after i hit that brick wall, it seems this little NUC do not have enough PCI lanes to pass over the IGP... I already moved on and decided to have a separate machine for general stuff(some mini PC, but with a beefier CPU and IGP) and a desk PC for gaming with its own white listing HW firewall.
