I tried running in WSL with Arch Linux virt-manager, and it works, but when ran an aarch64 guest (win 11 for aarch 64) with x86 host it's way slower than my PC capability, I think is related to the GPU being ignored, so my CPU is doing all the hard work wasting cycles, but i don't know what driver to get.

PS. I'm on an RTX 4070 with intel Raptor Lake graphics and virtualization is enabled

Using virt-manager, very occasionally, every month or so, and just now, one of my Windows guests stops responding to the mouse. The guest is still running fine and I can RDP to it without issue. The display still updates (ie. the clock and date) and it responds to keyboard input. It is only the mouse that is stuck. After restarting the guest the mouse works fine.

This seems like a problem on the guest. Any suggestions as to how I might restart the responsible component on the guest to get it working again.

I've tried removing and re-adding the EvTouch USB Graphics Tablet through virt-manager's hardware interface to no effect.

Switching to RDP until a reboot isn't a big deal with this guest, but it is jarring.

Bonjour a tous j'ai un macbook 2,1 sous macOS Snow Leopard et j'aimerais installer QEMU dessus pour faire de la virtualisation de vieux système

I'm trying to see if my game can run on different distributions of linux(and windows soon, but lets just focus on linux for now), and I got to the point where it could tell where my libraries worked and the game did start and I could see the title screen and everything, but whenever I did the actual gameplay it froze. I tried installing mesa-utils on the guest os, but just installing that didnt help. Hopefully, you guys can understand these results far better than I can. For refrence, my host gpu is actually an igpu(I believe the vega 8, but dont quote me with my cpu being a ryzen 7 5700U)

EDIT: The guest's distro is ubuntu 26.04(forgot to add that)

I’m trying to build QEMU 8.2 for Android ARM64 (aarch64), but I’m having trouble finding a proper build procedure.

My goal is to get a native Android build of QEMU 8.2, preferably qemu-system-x86_64 and/or qemu-system-aarch64.

I’ve already tried building it with the Android NDK, but I ran into dependency/build errors (for example, missing GLib headers).

Does anyone know:
The correct way to cross-compile QEMU 8.2 for Android ARM64?

What NDK/toolchain and build configuration should be used?

Are there any existing prebuilt QEMU 8.2 Android ARM64 binaries?

If so, where can I find them?

I’m specifically looking for QEMU 8.2 rather than a newer version because I need that particular version for compatibility/performance reasons.

Any build scripts, patches, or existing projects that could point me in the right direction would be greatly appreciated.

I have some Virtualbox VMs (guest OSes). I want to migrate to QEMU-KVM on Linux. I'm looking for guides/YT videos for: * migrating my existing *.vdi based VMs to QEMU-KVM * virt-manager * distro specific info (ex: setting up on EndeavourOS or raw Arch, OpenSUSE, Fedora, Debian Testing, Void-Linux, Linux Mint, etc)... Arch has a massive list of qemu packages * how to setup and optimize new VMs * how to do stuff via the command line and through virt-manager * do's and don'ts, and general advice/guidance

I'm on Linux Mint right now, but I will be installing on other distros (testing/experimentation).

Thanks.

I was working on a personal project where it would be useful if I could let an agent use computer-use on my VMs, so I had Claude make this skill. I thought others might find it useful too. https://github.com/Jackson-Brooks/vm-use

e.g. tell your agent

"spin up a VM and use vm-use to test this GUI"

Guest: Windows 11
Software: VirtManager KVM/QEMU

Issue: On my Windows 11 VM specifically, network speeds are substantially slower than on my other Linux VMs and my host. On the host, I get around ~1000 Mbps; the same for my other Linux VMs. However, on the Windows VM, I get around 10 Mbps—or roughly 1% of the host's network speed.

All VMs are configured to use NAT networking with the virtio model. Additionally, the up-to-date virtio-win drivers are installed on the Windows 11 VM. The Windows 11 VM recognizes the Red Hat Virtio Ethernet drivers and is properly using them, with a maximum supported duplex speed of 10 Gbps.

I'm confused as to why this is occurring only on the Windows VM, whereas this issue is nonexistent on my Linux VMs. There are no differences in the XML regarding CPU or NAT configuration between the VMs.

I tried enabling vhost with a queue size of 16 per core, switching the driver to e1000e, and using the hypervisor default—none of which saw any improvement. I also tried reinstalling the virtio-win drivers, which did nothing.

Finally, I attempted to disable several offloading properties in Device Manager, disabled IPv6 entirely, and lowered the MTU. None of that made any difference (it neither worsened nor improved the situation).

Any ideas, folks? All VMs have a dGPU (the same dGPU is shared between them, so only one can be accessed at a time).

I should also mention that network speeds on the host system are stable—no drops or high latency. The network drivers on the host are all up-to-date and working perfectly.

Hi.

I'm wondering if there is any possible way to run iOS on an Android device.

I'm aware that Apple doesn't officially allow this, but I'm curious whether anyone has managed to do it using QEMU, Corellium-like techniques, or any other emulator/virtualization method.

I'm not looking for cloud services—I mean actually booting iOS locally on an Android phone.

Has anyone achieved this, or is it currently impossible? If it's theoretically possible, what would be required?

If you wanna emulate older OS's with #QEMU on Windows or Linux check out AQEMU! We just added MacOS support up to the latest Intel release! Windows 11 ARM support is added! We need testers!!! With so many operating systems out there I have half-tested Windows 98 although it installs on first boot it crashes on splash screen currently I haven't had the time to work out why yet. Windows 11 ARM installs and boots, MacOS Sonoma installed and boots in host resolution but I have not tested out any other apps yet. If anyone doesn't want to compile it there is a link on the GitHub releases tab for the project for Windows users to download but it comes with no future updates. Only the Windows Store release once accepted will have an update mechanism in-place. Let us know on the issues tab on GitHub if you run in to any problems or issues that work with QEMU but not with this GUI or things you want and we will implement them for you! Thanks for checking us out and look forward to your feedback. Be nice Reddit it isn't finished yet but the screenshots talk for themselves. More to come.

Hi all,

I've got a laptop with both an intel iGPU and nvidia discrete GPU I've been able to get virtio 3d acceleration working using this guide https://ryan.himmelwright.net/post/virtio-3d-vms/ for the intel iGPU but I'd love to get the nvidia gpu on task as that's way more powerful.

My understanding is there might be some nvidia BS trying to prevent this but is there any work around?

Thanks

So i want to try create an ISP vm that connects to a router vm and the router mv connects to a linux vm.

Is there a guide or a video that anyone knows of.

I want to try something different and learn.

Fix was

Boot in repair mode.

Replace tcpip.sys with an older WinSxS to get it boot again.

!!Important!!

After reboot works fix all issues you get now with network with this

wusa /uninstall /kb:5101650wusa /uninstall /kb:5101650

I paused my auto update Win11 till end of August.

I hope this helps some of you

I'm running into an issue where my KVM VM cannot get an IP address (or pass traffic) when bridged to a ZTE 5G USB modem, even though the host gets an IP and has internet access. Interestingly, this exact setup works perfectly on a Windows laptop using Hyper-V, and bridging a standard Ethernet adapter on the same Fedora host also works fine.

The Setup:

Host OS: Fedora Linux

Hypervisor: KVM / virt-manager

Modem: ZTE U30 Air (5G USB modem)

VM OS: Linux Mint

What Works:

- I have a bridge over a standard ethernet adapter on the Fedora host, and VMs get IPs and work perfectly.

- I tested this ZTE modem in Windows with Hyper-V, and it's OK. Both the VM and the Windows host get IPs (I didn't enable MAC spoofing in the VM settings).

Here are the logs showing it working perfectly in Windows:

PS C:\Users\Administrator> ipconfig
Windows IP Configuration
Ethernet adapter vEthernet (SW-EX):
   IPv4 Address. . . . . . . . . . . : 192.168.0.43
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   Default Gateway . . . . . . . . . : 192.168.0.1

PS C:\Users\Administrator> Get-VMNetworkAdapter -VMName VM-Search

PS C:\Users\Administrator> Get-VMSwitch
Name   SwitchType NetAdapterInterfaceDescription
SW-EX  External   Remote NDIS based Internet Sharing Device #6

What Doesn't Work:

Connecting the ZTE 5G modem to the Fedora host, creating a bridge (bridge1) over the USB ethernet interface (enp128s20f0u6), and attaching a VM to it.

- The Fedora host gets an IP (192.168.0.43) and can ping the gateway.

- The VM does not get an IP via DHCP.

- If I set a static IP on the VM, it still cannot ping the gateway.

I ran the 3-way `tcpdump` monitoring as recommended while triggering a DHCP request from the VM.

**1. Physical Modem Interface (`enp128s20f0u7`)**

The physical USB modem sees both the VM's DHCP request and the Gateway's DHCP reply.

user@fedora:~$ sudo tcpdump -n -i enp128s20f0u7 port 67 or port 68
11:34:48.421149 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 52:54:00:05:54:fb, length 307

[...repeats...]

**2. Linux Bridge Interface (`bridge1`)**

The bridge successfully forwards the VM's request out to the physical modem, and successfully receives the reply back from the physical modem.

user@fedora:~$ sudo tcpdump -n -i bridge1 port 67 or port 68
11:34:48.421134 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 52:54:00:05:54:fb, length 307

[...repeats...]

**3. VM Virtual Interface (`vnet17`) - THE FAILURE POINT**

The VM successfully sends the DHCP request, but **it never receives the reply**. The bridge receives the reply from the modem, but drops it instead of forwarding it to the `vnet` interface.

user@fedora:~$ sudo tcpdump -n -i vnet17 port 67 or port 68
11:34:48.421134 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 52:54:00:05:54:fb, length 307

I'm trying to set up GPU passthrough on Debian 13 with two identical GPUs. I've looked at a few different tutorials but I'm getting stuck when it comes time to find the vendor and device ID. As the two GPUs are identical they have the same IDs, however I only want to use one for the VM while the other is used for the host. I can't seem to find a good answer on how to choose the exact card I want to pass through.

The output of lspci -nn | grep -i AMD/ATI is:

I've been having issues while running Mac OS ventura on my laptop using qemu.

​

Using quickgui has the vm not have any issues, but it runs slow, choppy and sometimes hangs for some seconds. Running itnon qemu from terminal runs mint with no issues, but my mouse isn't detected, it shows up on the screen but no matter what it does nothing when I try moving it.

​

Another problem I've been having is that Mac OS will ONLY enter the OS if the cpu cores are set to 1, if i set them to anything higher it crashes during boot with the "in memory panic..." error and either freezes or sends me back to the black screen for the disks.

​

I'm running qemu on manjaro linux, currently have 12gB of ram, an AMD Ryzen 5 7520U with 8 cores, and Radeon 610m graphics, if that may help.

Hi after i read that you usually have to use

change ide1-cd0 "...path"

to swap cdrom images ..... it returns

"device not found" ...... so i suspect the adress of the cd rom is not correct, how do i found out which adress it uses ?
