Win 7 in virtualbox that already runs in virtualbox? - virtualbox

Can you install win 7 in virtualbox that already runs in virtualbox of a nother win 7? Question also implies for any other operating system.

Each virtual machine is technically "independent" of one another, and with VirtualBox, you could easily do this, since it is supported on both Windows and Linux host operating systems (emulated or not). You could simply use Windows as your "base-host" OS, run Linux in a VM, and then use that operating system as the new base-host for Bochs.

Your question is not fully clear to me. If you mean running a virtualized Windows 7 within a native Windows 7, this is perfectly possible, as any other OS/OS combination. It will just eat up a lot of ressources. If you mean running a virtualized Windows 7 within another virtualized Windows 7, then you will run into trouble and you would better run the 2 virtualized Windows 7 in parallel on a single native OS.

Any problems in installing ROS on Windows 10 using Virtual box

Is it a good practice to install ROS (Robot Operating System ) on Windows 10 using a virtual machine ? Are there any limitations that I would face doing so ?.
I know its a basic and simple question. But as a beginner I think I must get help on here
As far as ROS itself is concerned, running it in a Linux VM should be fine. Depending on your usage you may run into trouble brought by software used alongside ROS.
Gazebo for example will likely run very slowly if at all on a VM (though it's true this again depends on hardware). I was unable to get it to run properly on an Ubuntu VM so I just started using Ubuntu as the host OS.
Try dual booting Windows and Ubuntu if you cannot drop Windows entirely.

How come my OS crashes when I have more than 1 core on VirtualBox?

I have an XP 32 bit installation on VirtualBox, but whenever I want to increase the cores of the cpu to more than one core, the OS won't boot! What's going on?
These two links might help:
How to change XP VM on virtualbox to have two CPUs without having to reinstall XP
VirtualBox - XP guest does not see multiple cores/multiple processors
You can try ways provided in these two links. If they does not work, you might need to reinstall.
I found the problem! At least in my case.
The problem was that I had "Virtual Machine Platform" feature enabled in Windows features.
I had looked and looked but many nothing said about this, some people said to just turn off Hyper-V which I did but same problem. So I decided to disabled everything that had to do with "virtual" then it worked!
Also I downgraded to WSL1
Don't turn off Hyper-V, otherwise it may give you some problems like slowing down your VM (atleast it did for me).
Disable Virtual Machine Platform
Enable Hyper-V as this allows you to run WSL and Virtual machine together
And if you really want WSL also enable "Windows Subsystem for Linux"
Downgrade to WSL1

Decent cross-compiler for Mac OS X targets

I'm developing an SDL application in C++, and some of my consumers have asked for a version that runs on Mac OS X. I am wondering if anyone knows of a good cross-compiler for Mac OS X targets, and maybe a Mac OS X emulator (maybe a virtual HDD for Virtual Box?) so that I can actually test it myself.The emulator is not 100% necessary though, as it's probably illegal and I can understand if nobody's willing.
I'm using a PC (Windows XP) for my host machine, and I don't have the funding to go and purchase a Mac, sadly.
The easiest, and most common, solution is the other way: use a Mac platform with Windows installed either as dual boot or in a virtual machine.
That way you will benefit of 100% of both worlds and never be bothered whenever a Mac system update is delivered.
Bonus: You can install Linux as well.

about turbo c working under windows 7

i am using windows 7 64 bit laptop.i installed turbo c and write programs using dosbox, but i can't run the program.... when run is selected it show some message like not an :exe plz give solution to this problem
64-bit Windows cannot run 8- or 16-bit executables due to limitations of Long Mode. Use gcc via MinGW or Cygwin to build them instead.
It's a DOS program you're building. So you'll have to run it under DOS, too.
Do not use shortcut ctrl+f9 to run program as it is also a shortcut to close DOSBOX. use menu tab to compile and run programs.
If you can "live" with it, I run a VM over my linux and win7 (dual boot) with windows XP as the guest OS. This way, I just boot up the VM as necessary. VMWare and virtualbox are good ones.

VMWare 6.x on Vista 64 runs as *32 task

I am trying to run VMWare Workstation 6.5.1 on Vista 64. It runs, but always as a *32 task. It is supposed to run as a native 64 bit task. I have uninstalled and reinstalled with no change. Any ideas?
Machine is a ASUS P5K, Intel Q6600 cpu, 8 GB RAM.
Thanks for any insight.
VMWare runs as a 32 bit task, but can still run 64 bit applications if you are running on hardware the supports the VT extensions. It can also access more than 4GB of memory because it plays a lot of tricks in the background.
Not sure what it is "supposed" to do, but mine runs the same as yours. Haven't had any problems with it either - in fact I am totally impressed with it having had it for just 2 weeks now. Amazing product.
I have a collegue with a very similar configuration, vista 64, vmware workstation 6.5. His VMS run as native 64 bit tasks in taskman. I have also seen other threads on the net that complain of the same issue. It appears that vmware workstation can indeed run as a native 64bit task and that there is a noticable performance difference yet no one seems to know how or why it sometimes runs as *32.
