I have Dell XPS M1530 Laptop and CPU is Intel Core2 Duo T8300 2.8Ghz. I have set Visualization Technology On in BIOS and install Ubuntu 12.04 on VirtualBox but in /proc/cpuinfo vmx cpu flag doesn't appear. Even in VirtualBox i have enable VT-x option, Am i missing something? I want to install openstack on it but without VT support i can't run nested VM. Please suggest.
EDIT:
I have attached CPU identifying tool screenshot.
If I am reading your question correctly, you have enabled VT-x in the BIOS and VirtualBox is able to utilize it from a Windows host, but it is not presenting VT support through to the guest operating systems?
If that is correct: that is because - to my knowledge - VirtualBox does not support virtualizing VT support for guests. See this ticket for some discussion: https://www.virtualbox.org/ticket/4032
Have you taken a look at this SO question? VirtualBox and vmdk vmx files
For some reason it was closed by SO, but seems to have good information.:
VMDK/VMX are VMWare file formats but you can use it with VirtualBox, just create a new Virtual Machine and when asks for a hard disk choose "Use an existing hard disk" and click on the "button with folder and green arrow image on the combo box right" which opens Virtual Media Manager, it looks like this (you can open it directly pressing CTRL+D on main window or in File > Virtual Media Manager menu)...
And then you can add the VMDK/VMX hard disk image and setup it for your virtual machine :)

I am using ACER Aspire E5-553G-F1J2 with AMD Fx9800p processor. My computer's bios don't have feature to enable virtualization. So can in run Android emulator without hardware virtualization VT-x or AMD-V ?
You can't use Intel based images without virtualization enabled and IntelHAXM installed. but you can use ARM images which does not requires hardware virtualization.
To run ARM images:
Open AVD manager.
Create a new 'Virtual Device' or 'Duplicate' existing image
Choose arm* images
Continue with the wizard.
Run!
Note : ARM images are available only till API level 25 only and might be slow, have patience.. Cheers :)
Currently I have Ubuntu Linux running on my MacBook Pro. I want to try out OS X again, but keeping Linux for now. Can I install OS X to a USB drive without touching my internal storage?
Your external drive needs a GUID partition with at least 8 GB of available space to install OS X. For best results, the volume should be formatted as Mac OS X Extended format (not FAT, NTFS, or EXFAT).
Attach a USB, FireWire, or Thunderbolt storage device to your computer, or insert an SDHC or SDXC card into the SD card slot if your Mac has one:
Set up a gpt partition table
Restart up your Mac. Immediately after you hear the startup sound, press and hold the Command+R on your keyboard.
After you see an Apple logo or globe appear, you can release the keys. If you're prompted to select a Wi-Fi network, select a network that has a working Internet connection.
When the Recovery screen appears, make sure you're connected to the Internet. If not, select a Wi-Fi network with a working Internet connection from the Wi-Fi menu.
Select the option to Install OS X from the Recovery window.
Follow the onscreen instructions to complete the installation. When you're asked to select a drive for installation, click the button "Show All Drives". Be sure you select the external storage device you've connected for this purpose, not your computer's built-in startup drive.

I want a Linux image which can use low resources (RAM & CPU) and is capable of running:
1. Virtual Box
2. A browser
Actually my system does not have enough memory to run Windows Server in Virtual Box so I need that solution.
I suggest you to configure the kernel as you wish. By default, so many services/resources come with Linux. Which eats most of memory and CPU time.
For compiling Linux kernel pls refer http://www.cyberciti.biz/tips/compiling-linux-kernel-26.html
If you wish to reduce your file system size then plz refere http://tldp.org/HOWTO/Bootdisk-HOWTO/buildroot.html
I think Suse Studio is fine when need to customize the Linux image.
I have installed Linux-Mint on my VMware Workstation8 but I don't know how to make its screen fit inside the VMware client screen even when I resize the VMware windows.
As far as I know, VMware doesn't support scaling in that fashion. You should try VirtualBox, as it has an option to Scale-To-Window.
Take a look at http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1003
That's for windows but it's the same issue for linux. Basically you need to play with vmx file.
Is there a way to figure out if a win 2003 server server you are connecting to is virtualised? I tried asking but not 100% sure of the answer is correct.
This is a duplicate of this question: How to identify that you’re running under a VM?.
Quoting from the accepted answer to that question by JawnV6:
The classic trick to detect a VM is to populate the ITLB, run an instruction that must be virtualized (which necessarily clears out such processor state when it gives control to the hypervisor), then run some more code to detect if the ITLB is still populated. The first paper on it is located here, and a rather colorful explanation from a researcher's blog is located here.
I guess looking at the Device Manager (Control Panel | System | Hardware | Device Manager) should give you a good idea.
On one server, running on VMWare ESX, I see the following tell-tale signs of a virtual machine:
System Devices: VMware server memory controller
Network adapters: VMware Accelerated AMD PCNet Adapter
Mice: VMware Pointing Device
Disk drives: VMware Virtual disk SCSI Disk Device
A simple test that detects a VMware network adapter, is:
ipconfig /all | grep "VMware Accelerated"
(would perhaps also detect a host running VMware workstation)
Here's a decent explanation. You can check the manufacturer of a piece of hardware from WMI or within Device Manager to determine if it's a physical device or not.

Can you tell us any more about how you're connecting to this server?
This depends on a couple of factors.
Are you using remote desktop to connect to the server and can you gain access to system files and folders?
Do you know what type of virtualization software is running the server?
Without know that information this question may be a litle difficult to answer correctly. There are a large number of virtualization software vendors and each of them have different setups that are in the virtual servers.
Without more information, the short answer is no. To the actual guest operating system it looks and acts like an operating system that is running on bare metal.
You could look for support software installed, for instance VMware usually installs VMware Tools on the guest operating system.
