Sorry to have to ask, I do notice it looks like the dependencies are available for windows host/Msys2. Please and thanks.

Hi,
I installed windows 10 on mvisor. guest os is running and has internet access, but no access to local host. Also, no access to host file system.
How to configure access to local network and host file system?

There is no problem with windows 7 installation but Windows 10/11 not work for me. I tried LTSB 2016 / W10 22H2/ WIN 11.

我正在试用它, 所以按照你的build进行下去, i440 与 q35 也切换了, 但还是出了问题.

$ ./mvisor -c ../config/1.yaml

只是改了vcpu为2, ata-cdrom, ata-disk, hypervisor, 其它配制什么都没改变.

Hello. I can see that, with exception for seabios and cpuid, along with the chipset emulation, there is no x86 architecture bound code in this project. As it stands, both KVM and Hyper-V have aarch64 support which is transparent for the applications. Therefore, almost all of this code should work fine on top of the aarch64 KVM. Are there any plans of implementing the aarch64 support? It would be nice to have an alternative for Qemu.

I have a few questions regarding the key differences between mvisor and QEMU.

I think it is unlikely that mvisor would outperform QEMU in terms of speed, since both of them are using KVM.
Does mvisor have a significantly smaller memory footprint or lower CPU usage compared to QEMU?
Does mvisor offers any additional functionality than QEMU?

Specifically, I would like to know if mvisor can be used as a gtk-widget or qt-widget, allowing it to be seamlessly embedded in GTK or QT applications. QEMU + spice-gtk-widget solution is heavy and complex, since QEMU needs to be managed as a separate process, and QMP protocol and SPICE protocol must be used to interact with it.

Cool! An alternative for QEMU with KVM support! 🙂

I have a feature request for mvisor:

Would you consider adding support for virtio-snd? The Linux kernel has had a guest driver for this VirtIO device for 2 years (since kernel 5.13), but until this day, QEMU has not yet delivered host support for it.

It would be nice to have at least one open-source hypervisor that could make use of it.

Thanks for considering!
