As far as the author's experience is concerned, there are two effective methods, and we introduce each one.(1) Network access sharing method:Another way to realize resource sharing is to access it through the network, just like our traditional means. When we establish the conn
Because the network configuration of the VM is always forgotten. Special note down.1. Similarly, turn on the virtual machine's NAT and DHCP service to set the virtual machine's NIC to NAT mode.2.vmnet8 is automatically acquired by default, and the host's local connection does not have a shared connection.3. By viewing the Ipconfig on the command line of the host, you can see that the VMnet8 IP is: 192.168.155.14. In the Edit menu of the

Whether you have encountered such a situation when using vm5. The physical machine has good performance and rich memory, but the VM runs slowly.
This is because a new function is added to the vmware5 version. The system will create a. vmem file for you. The file size is the size of the system memory of the virtual machine you have defined. This file is used as the swap space for memory. In vm5, only 16 MB of physical memory is used, and others are co
