When I try to copy large amounts of data to the VM guest from an external machine using scp, the transfer fails due to corrupt packet. If it were a hardware issue, the transfer would fail when I send a file to the Host server, but transfers to the host are successful.
I have tried a Ununtu 14.04LTS guest, and the Centos 7 guest (both 64bit). Both have had issues with packet errors during transmission.
However, a Centos 6.5 Guest in the same configuration does not have this problem. The transfer completes without issue
I can work around it by transferring the data to host, then using scp to the VM Guest.
I've used ethtool -t offline on the host and that passed.
The test on the VM Guest fails. I have tried nic types: virtio-net, MT Desktop, and MT Server
