I am developing some application in Linux .This Linux is a virtual machine running in Windows, with the help of VMWare player. When my Linux application access the peripherals (say camera , network ..) , the access goes through the parent host machine's drivers (Here Windows)?
The idea is to know whether changing the Windows driver capabilities will affect my Linux application.
(The question is not about whether the data will flow through windows. It is about whether the corresponding windows driver get called - e.g for Linux Video, whether the corresponding Windows video driver will be invoked).
There is no other way for the virtual machine to control the peripherals but via the drivers. Please note that you may have some settings in the VM that add more restrictions then the settings of the external driver, but for sure you will never have less.

I am trying to run windows software in fedora OS. There option of dual booting. But is there a way of creating a virtual environment, like we create environment for various python project, in which we can run .exe files and use microsoft office softwares (word, excel, etc.)? It's a weird question, but I searched the internet but not able to find it out.
yes, you can easily do so with the help of VmWare or VrtualBox, or any other similar applications.With a virtual machine application like VMware, you can run another operating system inside your current operating system.
It's running an OS inside another OS,also, you can store and run multiple OS (not simultaneously though) with the hep of these virtual machines.

I have Linux both command line linux, and Ubuntu, but my computer is Windows 10 based. Also the hardware is not what it used to be. I.e... No working USB port, No DVD slot (But I do have a Micro SD slot if I can boot it from there) but I was wondering if I can install and boot linux directly in Windows? And I was wondering if Windows 10 would be active still, and if I an switch in between the two? I have never worked with Linux or booted it. How can I boot linux in windows without anything but a micro sd card?
you can not boot linux on windows. you can make Bootable USB and use live linux or use virtual machine like VMWare
Use a virtual machine. They allow you to run multiple operating systems at once, and as long as your machine supports virtualization, they work perfectly for the situation you are describing.
My preferred virtualization software include:
VMWare
and
VirtualBox
From there, download and install the Linux .iso file of your choice to be able to open and switch between operating systems at will. Also, make sure to enable virtualization in your BIOS settings.

I set up a virtual machine with Ubuntu Server edition.
When I boot it up, the output from the console appears on VirtualBox's virtual screen. This means the machine is wasting resources trying to display output on a screen. It's just a text terminal, I know, but it still requires resources. Why waste them when I'm going to only access remotely through PuTTY?
I know that VirtualBox can start a virtual machine in "headless" mode, but I fear it will just disable VirtualBox's output window, with no real impact on the virtual machine itself.
My questions are:
Will my virtual machine still detect a monitor attached when it runs in headless mode?
If so, how big is the performance impact of this situation? Is there any way to avoid it?
It does not require any additional resources. Just a tty device and a blocking getty process which requires no CPU resources and which has would both have been created anyway. (Every Linux system that I know starts 6 ttys by default).

i am trying to get the remote access from windows system to linux system using teamviewer but when the connection is established the windows system sees the black screen. so anyone can help me how to establish the fair connection.
I had the same problem - for me with two solutions. On some systems, it just took about 30sec for the screen to build up (in that case, just be patient) and in the other case, there was a driver problem. Try to change the driver to the default ubuntu one and deactivate the proprietary hardware driver in that case.

In terms of Webserver and low package size installation.
To be honest, the best distro for VMWare is the one the admin has the most experience with. With the GUI stuff all disabled I've not found any difference in performance between RedHat, Centos and Ubuntu when running VMWare.
Picking the distro that you can adminster easiest will save you hassle. If you already have a few linux systems using the same flavour makes the admins job a lot easier.
It is not clear to me if you are asking about the distro for the Vmware host, or for the guest operating system that will be your web server.
I generally really like Debian or Debian based distributions. But as far as Vmware is concerned Centos or anything really should work.
If you are looking at setting up many vms on this server you might want to look at using the bare-metal hypervisor product that has been released as a free product. (Vmware ESX)
