Even a well-designed VMware network will encounter some problems brought by virtualization, such as serious packet loss of virtual machines. Proper adjustment of VMware network settings can solve the problem of high packet loss rate without changing the sub-OS.

First, confirm that the virtual machine uses the VMXNET3 virtual network card driver. In this way, in the specific case of Linux host, many data packets will be lost when large data files are transmitted on high-bandwidth networks. Turning off the sum of receiving and forwarding checks can solve this situation. Because the function of checksum is to prevent the wrong packet from being sent, this will increase the risk. Considering that the error rate of Ethernet cards is usually less than one in a million, the risk level is not high.
