I Install MikroTik RouterOS 6.40.5 X86 from netinstall(and ISO version of package) to The Hyper-V Windows Server 2012 R2..Yes, i know what is CHR, but i need L license(Not P). In X86 package not woking a Virtual network adapters(The OS not see him) and Legacy virtual network adapters( in this example RoOS see "ether1", but cant use it- DHCP not work, static addreses see in neigbors, but unreacheble or "not route to host" in direct link).
If i install this version to VMware products: all is OK.

CHR to this Hyper-v server: all working, but license... I need L version of license.

Are you sure about the license? All P licenses are generally L6 just with tx limitation per port...

But if use L1 license i have 1 Full interfce, if P0 - 1Mb/s. There is a difference .
I build The Dude server on Hyper-v

Ok. Your choice...
