For the moment QoS is unlimited.
Actually for some tasks I wish to allocate 80% of 10Gbit interface,
but the VM interface is always 1Gbit.

The VM interface is virtual. It's not limited or set to 1G. Due to some ancient Windows certification requirements (that required that an interface would have a defined speed!), 1G was set for it.

Inside the QoS of the host interface I cannot put 8000 for the Rate
Limit, it claims that rate limit should be between number 1...1024,
looks like it assumes only 1Gbit interfaces?

I kinda remember we had this issue in the past - and it was fixed - please file a bug so we'll look at it.
