Hello, everyone.

I'm from japan and using machine translation, so I apologize if it's
hard
to read.

I am currently trying to build a virtual environment using Ubuntu and kvm.

However, I found out from the following page that the virtual machine
cannot use the bridge network because I am using a wireless network.

https://wiki.libvirt.org/page/Networking

I am having trouble with this because my PC is using a wireless LAN.

On that page it says "wireless interfaces cannot be attached to a Linux
host bridge",  I Can you tell me why this is so?

Is it a limitation of the NIC driver for the wireless LAN?
Or is it a limitation of libvirt?

Best regards.
