Summary
Errors while running a test if NV is enabled
Error
Some of the following errors appear only when Network Virtualization is enabled; if NV is disabled, we don’t see these issues:
Load Generator failed.
Error: Client (-connection_id=)(-server_type=8)(-server_name=XXX)(-server_port=54345)(-server_fd_primary=2)(-user_extra_data=NAME/IP)(-use_default_configuration_path) is not responding. [MsgId: MERR-29992]

Error: Service client with id=303 failed to post a message ,reason - target process/thread doesn't exist. [MsgId: MERR-29739]
Cause
NV driver does not support MTU 9001 for Ethernet protocol, we support Ethernet 1500.

Fix
Run the following command from the CMD on the LG(s) involved on the test:
netsh interface ipv4 set subinterface "Ethernet" mtu=1500
