Virtual-ethernet on Mikrotik Chr

Dear Forum users & Team
i have requirement of virtual Ethernet on mikrotik chr
in wiki i found following requirement
“on x86 architecture you have to have kvm package installed”

may i know what exactly it means ?
How can i achieve virtual Ethernet requirement on mikrotik CHR?

can you guys help me please.
Thank you

On download page under RouterOS - x86, locate “Extra packages” (the top one, there are currently listed two rows with the same description) for your exact ROS version. Inside there’s “kvm-.npk”, install it in your CHR, reboot CHR and you’ll have KVM package installed.

Thank you for solution sir

can i try this on rb4011 ?
Also can you tell me how to install mikrotik chr on local machine? i installed it on cloud using tutorials in wiki but dont know where to start on local machine
Thank you

You may want to start by reading CHR manual which covers also installation.
