Description of problem: Version-Release number of selected component (if applicable):checked and 3.3,3.4, and 3.5 How reproducible:Always Steps to Reproduce: 1.Install Ovirt, on a host with 1G interface 2.Create new Windows VM. 3.Check the interface speed, will be 10G Actual results:A guest Nic with 10G speed. Expected results:A guest Nic with 1G speed. Additional info:
The Guest Nic is supposed to be the same as the Host Nic "Same speed", the acctual results are different. When creating a new virtual machine and deploy it on a host with 1GB Nic. Attach that interface to the GuestVM, the Nic speed will become 10GB ....
Could you share the output of vdsClient -s 0 getAllVmStats ?

For the record: nic "speed", and even more so vnic "speed", is a fake number that should not be taken too seriously. Actual traffic limit can be much more or much less than the stated speed. Regarding the vdsm output: it is clear that vdsm reports all vnic with 'speed': '1000' so maybe Engine can tell why turned into 10G.
Lior tells me that the 10G is what the Windows (or some monitoring tool) reports within the guest. This is a reasonable fake number, since the vNIC is of virtio type, and it is capable of such speeds (inside the host). Communication out of the host are limited by the bottle neck on the way to a destination. This can be the host vNIC, or a loaded switch on the way. In my opinion it is not a bug. It's just a fact of life that NIC "speeds" should not be taken too seriously.
