Have you considered having two launch scripts where one uses SB16 and the other something else? You have to change JUST a single line. I don't know how picky Windows 98 could be if you change the Hardware if you decide to boot with one or the other.

---

Of course, exactly such i plan to do.

Note that I haven't played around with all the environment variables and decided to just passthrough the Motherboard integrated Intel HD Audio (And Realtek codec) to my main Windows 10 VM, so I get perfect sound at the cost of having my host and other VMs are soundless. This may not be viable for Windows 98 due to the lack of Drivers unless you get an era accurate PCI Sound Card.

---

You are right there is not Realtek HD driver for Win98, its WinXP+

Is the same thing. You are going to leave the host headless. Also, you may need to configure some way to access the host remotely (SSH?) before doing that.

---

Sorry im a bit confused, does it means that i will lose my Nvidia primary GPu setup, when i will want to use iGPU pass through?
Even when i dont like mainframe relicts, i have ssh in order and im able to use it.. I know that you can even tunnel X through it..

Note that you're limited by Driver support, you can't use GVT-g for Windows 98. Windows XP was supported but I'm not sure if Intel dropped it.

---

I know that, im trying it making it working with Win7.

I have absolutely no idea about what you're talking about. There are times when your english is almost impossible to understand. I tried to decode and guess what you tried to say, but after reading it 5 times I gave up.

im very Sorry, im dis graphic.. so sometime i forgot some letters, or replace some with others.. there should be.. cd.. and guest.. that by lots of my post are edited, i usually trying to write something without review and later i find out that there error, review everything before, would mean give up to this behavior and im lazy of course. When i open Virtio cd, there is folder guest-agent, when i run it.. i dont get any message.. i only wondered is some ekvivalent of Vmware \Virtualbox guest tools?

I have found some info here:
https://wiki.libvirt.org/page/Qemu_guest_agent
https://pve.proxmox.com/wiki/Qemu-guest-agent
It really dont seems that it could do match.. there some freeze for backuping, but otherwise seems that all these thing could be done through basic qemu monitor too.. tehre stop command too, im using system_powerdown through it all the time. I Really dunno if there is any difference..

Vmdk mounting
I found about that is possible through vmware Workstation gui, its not able in Player, but with Workstation have feature parity of this with Windows. I saw some tutorials, that is possible to do it from terminal, so i asked for some recommendation, it could be good for people without Vmware Workstation license.. i of course prefer GUI Vmware way.. I only had to run it with gksu to mount it from NTFS partitions..

I have found easy way how to install newer Qemu to Ubuntu and its clones..
https://mathiashueber.com/manually-updat...n-ubuntu-18-04/

This 3rd party repository, but there is only 2.12 so no big upgrade, but better than nothing..

Ok i managed to install newest and shinnest Qemu to Ubuntu base systems, by this tutorial:
https://askubuntu.com/questions/1067722/...on-ubuntu-18-04
Just replace qemu 3.0.0 for you wanted version.. i tried its working fine. Its will replace system one, there is not unwanted directory mess etc.. i dunno really understoop all checkinstall options so i used default for everything..
Goog news is that it could be removed by:
dpkg -r qemu

So you can try it until you will satisfied with result.

Pass through is still working, i only had to remove option -balloon none , it probably changed syntax.. i checked docs, but im not really sure how to set it up, is -ballon 0, is ekvivalent of ballon none..

I would take at least temporarly few GBs of space, but after end you can delete temp folder where you downloaded, extracted and build newer version..

I tried enhanced keyboard line for input release, but its not working.
I tried CRTL+ALT,CRTL+ALT+G.. left and right CRTL and ALT, so far i got nothing, input is still locked within virtual machine, i will try it with more moder Oses if it matters or not.. With Windows version, without pass through its working fine..

You CAN do passthrough of all your Video Cards to different VMs, leaving the host headless, but as I said before, this may not be convenient considering that the Intel IGPs offers the only form of GPU Virtualization available in consumer Hardware. While there is some overhead, GVT-g is far more convenient than IGP Passthrough. I would experiment with it before trying passthrough.
You may also want to read QEMU documentation about the matter, if you want roughly the same information worded slighty differently: https://github.com/qemu/qemu/blob/master/docs/igd-assign.txt

The QEMU Guest Agent Drivers comes bundled in the VirtIO ISO. However, as far that I know, it is of very limited usefulness - I don't even know of any really useful scenario where it may make a difference. It just opens a direct communication channel between the host and the guest, but there are no common applications for it. Thus, it is nowhere near as good as Virtual PC or VirtualBox ones, as those allows for host and guest desktop integration.

I just looked into other emulated Sound cards, it not looks good.

ES1370 - im able to install drivers, after restart im getting that device is working, but i ran some games im getting only noise, or bluescreens.
AC97 - its reported that it worked at least in the pass, i tried driver 400 a 406, from realtek but i got only Code 11 error on device in device manager.
Crystal4231 - crystal4231 should be main chip, but not whole card, there are some crystal 4232-4236 drivers, i tried some no luck.. It was detected as Windows sound system, even it not worked too.

Other if they would work, both AC97 and ES1370 have also SB16 emulation. I didnt find anything like info about sound drivers recommended for Win98, there not so much info.

This one is nice, it seems that i have all ready for legacy iGPu pass through.. machine working nice through remote desktop, intel HD driver is here but still not picture from monitor output and legacy mod should had it.
I have one more indication that something not right, vanilla remote desktop is working, but when i use some advanced like Teamviewer and Anydesk to try test real 3D is working, if is enable in dxdiag (classic remote desktop disable these after connection) im getting only broken picture only some small bitmaps chucks.. so something is still wrong.. it not probably just video input problem.. I will try install normal TightVNC server on Win7 machine, if picture would be again broken or not..

As far that I know, there are like a million of different ways to mount VMDK images in Linux, but I have no idea about them since I use LVM volumes or RAW file images.

---

Why you are using LVM, i always though that is some "server thing", you have some home RAID? VMDK is nice for multiplatform usage, i can edit in on Win/Linux/Mac combo.. with qcow - i dunno how to directly edit in Windows, vhd / or vhdx has some problem on MacOS - but there is bigger change that solution edits.

I have absolutely no idea why it doesn't work for you. It did for the last guy that had your problem: https://www.reddit.com/r/VFIO/comments/7...ting_to_hotkey/
The method is OS agnostic since QEMU should always trap that key combination. Guest OS doesn't matter.

From link above, i dont really understand what means this

on the if01 device instead of the kbd one

What is that if01 device? In commands some keyboard mouse mix, its some mouse\keyboard combo set with some unified wireless receiver?

I also now with Qemu 4.2 have problem, that my original WinXP USB pass through is not working:
-usb \
-device usb-host,vendorid=0x093a,productid=0x2521 \
-device usb-host,vendorid=0x060b,productid=0x2312 \

Error:
(qemu) qemu-system-x86_64: -device usb-host,vendorid=0x093a,productid=0x2521: 'usb-host' is not a valid device model name
I dunno if syntax changed or i compiled it without some usb support.

For now i can bypass it by etdev, but its not ideal.

Im trying to make working PCI pass through PCI-E to PCI Pericom adapter ( Pericom Semiconductor PI7C9X111SL PCIe-to-PCI Reversible Bridge ) it has 2 PCI slots.

But im getting this error for Nvidia TNT 64 PCI:
qemu-system-x86_64: -device vfio-pci,host=09:05.0,x-vga=on,romfile=/media/Win7_64/VirtualMachines/!roms/TNT2M64.rom: vfio 0000:09:05.0: Failed to set up TRIGGER eventfd signaling for interrupt INTX-0: VFIO_DEVICE_SET_IRQS failure: Device or resource busy

Im trying Creative SB Live, i same adapter pass through part seems ok (there are 2 devices sound card main and special for gameport), but i have test it in Win98, i have time to do it, because it would mean setup other script with virtual VGA, because TNT2 is not working. I tried without rom file, but it was the same.

I will have to setup, if problem is just with TNT2 or also with other cards..

I added to tutorial post, how to download rom directly from card and how to check if is UEFI compatible or not.

BTW if you have already working whole setup, just add pass through of other card is 20 minutes thing..

Ok i made TNT2 passthrough working i forget to add line to /etc/modprobe.d/local.conf i only add whole devices.. i forget it because i made backup of file and made change to backup to original file..
alias pci:v000010DEd00000FBBsv00001458sd00003679bc04sc03i00 vfio-pci

Its actually interesting that if this is not working vfio-pci, but you still added device to list on the end of line:
options vfio-pci ids=10de:0142,8086:1912,10de:002d,1102:0004,1102:7003,8086:a170

that it is detected..

Lots of people have this problem, there is lots of bugs bla, bla its just bad or missing line.

After some initial passthrough success i tried to continue test with Pericom PCIe-PCI results are bad, i was able to pass through cards, but any of them fully worked. Unless some Trident PCI and Voodoo 3 PCi i other machine, im out of cards.. I still have some PCI soundcards to test, but i will remove videocard fan first and test on board native PCI slot which is using Asmedia 1083/1085 chip.. to discover if i have same issues with it or not..
Its always problem when only 1 guy is trying something, can easy to some mistake.. or i could have problem HW, but i was used that Pericom adapters 2 years ago and it seems to work fine.

Tested cards are results:
- ATI mach - typical segfault whe i try to execute machine
- ATi Rage XL - typical segfault whe i try to execute machine
- SB Audigy SE- when i trying to install driver and reboot, before device is found, i getting Windows boot freeze, with some invalid path error. I dunno, maybe but driver, its strange error.
- Nvidia TNT2 M64- im getting frezes after, i install card drivers, right on logon or after.. Before that i had high resolution. If passthrough is working, problem could be that its second Nvidia card in system. Second option is that card is half-dead - it so wanted to test it with other machine, when i got modern Linux login screen freezes (i needed to copy some drivers for Win98) - i though that card is half dead, but after i installed it into Windows 98 machine and played Quake for couple of minutes and it worked fine, so its probably ok.. It getting quite hot, so it could in theory overheated - but i doubt it.. because freezes where quite consitent on same places.
- Cirrus 5440 - physical machine refuse to boot att all, this card is not big fan of any new board, even without adapter
- S3 virge - physical machine refuse to boot att all,this card is not big fan of any new board, even without adapter
- SB live - got machine freezes (main one) during card installation.

Also some mark that something is not good is that, from few times, i wasnt able to card in adapter by lspci. Its other indication that somethings is not good..

There is also idea that 2 Asmedia + Pericom controllers with one machine, are not good and Pericom would work fine with machine without native PCI slots.

There are 2 main possibilities, there is something wrong with Pericom adapter or with Pericom plus my MB combo.. or KVM PCI pass through is really picky from used card perspective, or not working great.

Ok some good news, i made AC97 audio working with 3.41 driver:
http://vogonsdrivers.com/getfile.php?fileid=1319&menustate=0
I tried vxd drivers for Win95 with both VIA controller, both are working, i know that someone prefer them. WDM - Win98 are working too - it tried that for "normal" AC97 Realtek and that for VIA, i dunno if exist some newer 3.x line drivers.
It has also some SB emulation - un tested by me, or it theory you can enable SB16 emulated sound card to, disable Relatek SB emulation and set primary sound card for Windows to Realtek and for legacy and Dos dual boot use SB16 emulation.

I also got some MSFN help with ES1370 Win98 drivers. I managed install them without exclamation mark, but from speakers im geting only noise and when i try to run some games, im getting bluescreens.. I dunno if problems is driver or Qemu bugs and missing feature, i havent read any ES1370 + Qemu success stories, so far.

Thanks to vogons friendls, i also tried to install intel chipset drivers.. i made it working without them, but i guess it should be better:
http://www.vogonsdrivers.com/getfile.php...menustate=30,28 its one worked.

I added also this and sound driver links to guide post and also with new Realtek AC97 3.62 driver, untested.

Good news, within native ASM 1083 slot TNT2 is working fine, i played Quake 3 for while and there are some ASM108x PCie to PCI adapters i have only one very clunky one (https://i.ebayimg.com/images/g/OyAAAOSwHv1eO3Jf/s-l1600.jpg ).. i need something better (if such thing exists). This one really only good to kill MB and addon cards.. it would need some card holder at at least.

Old ATI PCI which reporting segfault with Pericom do same thing on ASMedia native slot, so these cards are so far dead for passthrough.. i dunno if just feature or KVM Qemu bug..
