results of this experiment are similar to the previous ones. The figure looks better, but the saturated bandwidth of each situation is measured.
Even far lower than overload, we can find that packet loss in the virtual environment is several orders of magnitude higher than that in the physical environment (10-2 and 10-8 respectively ). These noises confirm the previous analysis-the virtual environment wi

This article is in contact with the Vmare virtual machine after graduation in the network part of the initiation of the article, quite worthy of study, let me realize that there are many unseen, know really too little. If I could have the same story,Understanding the principles of VMware's network composition and understanding the network in the Vmare vsphere architecture can be a great help. It's even helpful for helping to understand a lot of VMware

Most Windows users want to try out the charm of other operating systems, but they are afraid of installation troubles. In case of any problems during installation, using a virtual machine becomes the best choice. Speaking of virtual machines, "vmware workstation" is one of the best, but it also has many shortcomings.
First of all, it is a "expensive" software, wh

This process takes the longest time. In at least five years, N windows, Linux, UNIX, and MAC systems have been installed. Originally, there was only one version, and later there was a branch, currently, I have been using workstation products. At present, it is recognized that the best use of a green version of 6.0.5 is only dozens of MB, because I am willing to make it
1. First, you need to install Apache service, here does not describe how to install.
2. First configure window virtual domain to open hosts
Path is C:\WINDOWS\SYSTEM32\DRIVERS\ETC
After opening, write the domain name in the inside like www.cms.com
3. Modify the Apache configuration file httpd.conf

4. Modify Apache under Httpd-vhosts.conf
