Is it possible to Share 1 core for VM and Base Os?

+1 vote
65 views

Lets say, I have a system with only 1 core and with Windows OS. Using VMWare I am installing Linux on that. Can I share this core for VM and Base OS?

I mean if we have number of core 4 then in vmware we can assign 2 core. So, 2 Core for Linux and 2 core for windows. But what if I have number of core only 1, or if i have number of core 4 and in vmware I assign 4 core to Linux.

Will it share the core time wise?

Please understand the scenario -

I have installed vmWare in my windows PC, and using vmWare i have installed Linux. So basically I have 2 OS running at the same time.

Now below listed are my Queries,

1) I have inserted pen drive/Flash drive which i am not able to see in linux but in windows i am able to see it. Why?

2) Who manages the CPU?
Windows or Linux?
If windows manages CPU for its own process and Linux manages CPU for its own process, then what if number of process running in linux increases?

3) What about RAM?
Lets say perticular address of RAM is being used by Windows then how Linux will get to know that this address is not free?

4) How hardware is managed?
Lets say linux wants to do some I/O operation, so,, I/O operation is done by linux only or it takes windows in between?
If No then how Synchronization happen for that device?
If Yes then how Linux will talk with Windows?

Thanks in advance.

I am confused with all 32/64 bit architecture for Hardware/OS/Binary, Can someone please help in clarifying this queries?

  1. Of'course 64 bit hardware is faster than 32 bit, still there are people who prefer 32 bit over 64 bit hardware, Why so?
  2. If I have 32 bit Hardware then On that can I run 64 bit OS? (and vice versa)
  3. If I have a 64 bit Hardware and 32 bit OS then what will be the speed of my OS, as per 32 bit or as per 64 bit? (and vice versa)
  4. If I have 32 bit OS then can I run binary of 64 bit on that? (and vice versa)
  5. Is it necessary to compile binary with 32/64 bit both or we can compile with any and use it in both?
  6. Is the speed of the process also depends on type of binary that I have? For example, If I have 64 bit hardware and 64 bit OS but I have a binary which is compiled with 32 bit compiler then what will be the speed difference?

P.S. I know its basic and silly queries but lets clear now before it gets too late. :)
