Help!

[b1naryTR]

I have successfully compiled the thing, what do I do after compiling it? Please help. Thanks.

running sudo make install after your compiling will replace your official package "qemu-system-x86"

PS: if you want to undo it , you can reinstall "qemu-system-x86"

[b1naryTR]

After doing make install, I got "domain configration does not support video model 'xql'. When I tried to change it, I got "USB redirection is not supported by this version of QEMU." I tried both 6.2.0 and 7.0.0. Both are same, original version were working fine.

[zhaodice]

oh, you should add some features to support QXL and USB REDIRECTION Example: ../qemu/configure --target-list=x86_64-softmmu,x86_64-linux-user --enable-werror --enable-xen --enable-virtfs --enable-kvm --enable-libusb --enable-libudev --enable-spice --enable-usb-redir

This is my supports, if you are NO but I am YES, you should make it YES. more information see ../qemu/configure --help

qemu 7.0.0

is there any way to enable evertyhing or do I have to enter every parameter one by one?

is there any way to enable evertyhing or do I have to enter every parameter one by one?

it is unnecessary to enable everything , you can check your configure result which is NO but I am YES, find the "Optional features" , example you lack the "usb net redir" , the feature is "usb-redir" , so you should add "--enable-usb-redir"

actually, at least, I don't know how to enable all in one go

[zhaodice]

the interesting is if you installed dependents which the features needs, it is no longer have to add --enable-XXXX , the configure will enable every features which you has its dependents

Now I have "ERROR: Dependency "libusbredirparser-0.5" not found, tried pkgconfig". Is there any way to download all dependencies at once?

[b1naryTR]

Oh I just solved it myself, installed package "libusbredirparser-dev"

Btw I am trying to get valorant running on kvm, is there any crypology thingy I need to enable? Because my virtual TPM chip cannot prove file ownership.

[b1naryTR]

I just finished compiling, it still shows same error sadly.

Btw I am trying to get valorant running on kvm, is there any crypology thingy I need to enable? Because my virtual TPM chip cannot prove file ownership.

recently, I have tested the valorant on the vm(windows10 ) , Unfortunately my vm got blue screen(SYSTEM_THREAD_EXCEPTION_NOT_HANDLED) immediately when the valorant driver loaded, I don't know why...

[zhaodice]

I browsed the youtube, it said the valorant will cause blue screen in win10 , win7 will resolve it .. but my driver doesn't support win7,so I stopped my test.

[zhaodice]

hmmm,about TPM, you can passthough TPM to the vm, I guess it is helpful.

[b1naryTR]

I know about that, usb and xql are still fucked though

you cannot use virtual graphic, please passthough GPU to vm... virtual graphic is easy to detect

[b1naryTR]

I have a laptop...

[zhaodice]

I have a laptop...

I have a notebook too, I have passthough the NVIDIA to the vm haha

[b1naryTR]

tf, how did you do that? When I tried it I could not bind pci devices

warning, something has changed since linux 5.19... I recommend linux 5.15

[b1naryTR]

I have "5.15.0-48-generic" as uname says. I guess it is ok?

Uname -a output: Linux TULPAR-T5-V19-2 5.15.0-48-generic #54-Ubuntu SMP Fri Aug 26 13:26:29 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

It must be OK, because I am ubuntu 22.04 , linux 5.15 too

I probably have MUXless laptop, because in windows when I disable iGPU, screen goes to 30hz instead of 144.

I have passthough Intel(vgpu) and NVIDIA to the vm , so it is no problem

[b1naryTR]

Is there any way to install optimus-manager on ubuntu? There are only tutorials for arch. But there was something-switch included inside nvidia drivers.

I didn't install nvidia driver to my computer, nvidia driver serves vm only

[zhaodice]

this is my passthough result

[b1naryTR]

So, do I need to uninstall my drivers?

[b1naryTR]

Oh and usb thingy still isn't working

[zhaodice]

Oh and usb thingy still isn't working

usb redirect is not essential, you can remove it from your vm. your nvidia device must be handled by driver vfio-pci detail: https://lantian.pub/en/article/modify-computer/laptop-intel-nvidia-optimus-passthrough.lantian/

[zhaodice]

So, do I need to uninstall my drivers?

if you needn't it on your host machine, you can uninstall it… at least, I have no any nvidia driver in my host computer, only vm has it.

I am going to lose my mind, on build spice protocol and server support are marked yes but I can't fucking use spice. And xml editor on virt-manager doesn't work!!! When I enable xml editing on preferences it DOESN'T FUCKING WORK

[b1naryTR]

When I tried to remove usb redirectors it asks me to save the changes but I FUCKING CHANGED GPU SETTINGS and it doesn't apply either of them, just throws an error.

AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA

[b1naryTR]

I tried to create new machine but I can't. Because fuck me.

https://stackoverflow.com/questions/34001337/libvirt-error-when-trying-to-hot-attach-disk-on-guest-with-channel-qemu-ga it maybe caused by your xml which has some problem

[b1naryTR]

Looks like it's an XML problem but not sure how to fix it. I must say that it was working fine without patch and modified build. In my case, problem doesn't seem to do anything about disk. I get same error without disk.

Here is the log:

Should I try to create machines on arch? I am currentry using Ubuntu.

[zhaodice]

try to run ../qemu/configure and paste the result

[nhamhuynh79]

this is my passthough result
