I want to know that is it possible to create a fully portable virtual machine using any of the VMWare like products? My objective is to create a virtual machine (XP as guest OS), install some app in it, put the vm in a usb2 drive (performance is not a matter), and run it in any windows os (xp, vista, 7) without installing anything in host, using any host account (admin, guest, limited).
Is it possible to do that using any vmware like product? If possible then which one is my best bet?
Can't be done if you want to take advantage of Hardware assisted virtualization. Basically you need admin rights in order to access all the nifty features that make modern, hardware assisted virtualization so fast.
QEMU can run in a few different modes. When run as an emulator the processor is replicated in software, so hardware assisted virtualization is not necessary. This emulation is slow, but very useful if you're developing for embedded hardware that is different than your main PC.
Do you absolutely need to run the VM on top of Windows? If not, and if re-booting the hardware is allowed, you may be able to install a bootable OS on the USB drive. Boot straight from USB when you're elsewhere, and use the VM tool of your choice to boot from USB when you're back at your desktop (I know VMware and QEMU let you access a raw device).
You may also consider a bootable CD to get to a VM environment, then access the VM on the USB. I know there are CDs that will provide KVM or QEMU (I think Knoppix has it); I've not sure about booting to a VMware Server/Workstation environment.
Vmware ACE.
Specifically Pocket ACE. You'll need vmware Workstation to create the package. Check out the youtube video on how to do it. :D
[EDIT] Ace does not fit the requirement of having no Admin rights on the box.
Might want to Moka5. They supposedly support limited accounts, although they also mention requiring administrator access to install.
Vmware Thinapp will allow you to virtualize your app without having to go through the hassle of creating and running a whole VM. Here's another how-to video.
thindownload.com has a bunch of thinstalled apps if you want to try it out.

When I submitting to job I am using the following format
My questions are follows
1) Can I use my personal pc to execetute simulations. Like using VirtualBox and using one of the linux distribution ?
2) Is it possible to execute .out in the windows machine?
Sorry for my poor questions I am not expert on Linux systems.
Thanks.
However now I don't have access to execute my job files on the LSF
server.
You should talk with your cluster administrator about this. Transferring data from laptop to cluster is a common task. I'm sure that they have best practices.
1) Can I use my personal pc to execetute simulations. Like using
VirtualBox and using one of the linux distribution ?
Impossible to say with the limited information in the question. e.g., if your simulation software is licensed, then your laptop may not be eligible to use it.
2) Is it possible to execute .out in the windows machine?
Again, with the limited information in the question, its impossible to say. But in general Linux binaries cannot be directly run on Windows.
I want to run a PsExec demo, that simulates running a command on multiple machines in a network
Would I need a VMWare tool? I'm looking at Workstation 12 at the moment.
No, just ensure your firewall rules are correct and sysinternal tools are installed on each machine, file and printer sharing are enabled and that your antivirus product does not block psexec.
VMTools gives you things like drag and drop, shared drives, improved graphics and code wise PowerCli. That can do things like Invoke-script which allows you to run commands on other machines this might be alternative you want to use.
With VMWare Workstation Easy Install you can install an OS without any input. How does it do this? Is the support for this built into the OS, or does vmware do some magic to automatically select the correct options?
The support is built into the OS. For example, in the case of Windows guests, VMware generates a floppy disk image containing a txtsetup.oem and some other files used for Windows' unattended-installation feature.
For a bit of further information:
The easy setup leverages the existing unattended setup technologies present in given OS distributions.
In the case of Windows it does the above. In the case of most Linux distributions it would do a kickstart file (or the distribution equivalent if it's supported) based on the information you provide during the setup wizard in VMware.
Most OSes (most, not all) provide some method for unattended setups. A lot of this is the byproduct of no one wanting the prospect of having to manually install multiple machines. You can look here for more information on kickstart files used in RPM distributions of Linux and here for more information on unattended installations of Windows
We have the need to perform tests on localized platforms that put some burden on our hardware resources because for just a few weeks we might need plenty of servers and clients (Windows 2003 and Windows 2008, Vista, XP, Red Hat, etc) in multiple languages.
We typically have relied on blades with Windows 2003 and VMWare, but sometimes these are overgrown by punctual needs and also have the issue that the acquisition and deployment process is quite slow if the environment needs to grow.
Is Amazon EC2/S3 usable in the following scenario?
Install VMWare (Desktop because we need the ability to have snapshots) on an Amazon AMI.
Load existing VMWare images from S3 and run them on EC2 instances (perhaps 3 or 4 server or client OSes on each EC2 instance.
We are more interested in the ability to very easily start or stop VMware snaphsots for relatively short tests. This is just for testing configurations, not a production environment to actually serve a user workload. The only real user is the tester. These configurations might be required for just a few weeks and then turned off for a few months until the next release requires them again.
Is EC2/S3 a viable alternative for this type of testing purpose?
Do you actually need VMWare, or are you testing software that runs in the VMWare VMs? You might actually need VMWare if you are testing e.g. VMWare deployment policy, or are running code that tests the VMWare APIs. Examples of the latter might be you are testing an application server stack and currently using VMWare to test on many platforms.
If you actually need VMWare, I do not believe that you can install VMWare in EC2. Someone will correct & enlighten me if this is not the case.
If you don't actually need VMWare, you have more options. If you can use one of the zillion public AMIs as a baseline, clone the appropriate AMIs and customize them to suit your needs (save the customized version as a private AMI for your team). Then, you can use as many of them as you like. Perhaps you already have a bunch of VMWare images that you need to use in your testing. In that case, you can migrate your VMWare image to an EC2 AMI as described in various places in Google, for example:
http://thewebfellas.com/blog/2008/9/1/creating-an-new-ec2-ami-from-within-vmware-or-from-vmdk-files
(Apologies to the SO censors for not pasting the entire article here. It's pretty long.) But that's a shortcut; you can always use the documented AMI creation process to convert any machine (VMWare or not) to an AMI. Perform that process for each VMWare VM you have, and you'll be all set. Just keep in mind that when you create an AMI, you have to upload it to S3, and that will take a lot of time for large VMs.
This is a bit of a shameless plug, but we have a new startup that may deal with exactly your problem. Amazon EC2 is excellent for on-demand computing, but is really targeted at just a single user launching production servers. We've extended EC2 to make it a Virtual Lab Management environment, with self-service, policies and VM sharing. You can check it out at http://LabSlice.com and see if it meets your needs.
Amazon provides a solution themselves now: http://aws.typepad.com/aws/2010/12/amazon-vm-import-bring-your-vmware-images-to-the-cloud.html
I develop exclusively on VMs. I currently run Boot Camp on a MacBook Pro and do all my development on a series of Virtual PC VMs for many different environments. This post by Andrew Connell litterally changed the way I work.
I'm thinking about switching to Fusion and running everything in OS X but I wasn't able to answer the following questions about VM Fusion/Workstation/Server. I need to know if the following features from Virtual PC/Server exist in their VMWare counter parts.
Differencing Disks (ability to create a Base VM and provision new VMs which just add deltas on top of the base [saves a ton of disk space, and makes it easy to spin up new VMs with a base set of funcitonality]). (Not available with Fusion, need Workstation [$189])
Undo disks (ability to rollback all changes to the VM within a session). (Available in both Workstation and Fusion [$189/$79.99 respectively])
Easily NAT out a different subnet for the VM to sit in. (In both Fusion/Workstation).
Share VMs between VM Player and VM Server. I'd like to build up a VM locally (on OS X/Fusion) and then move it to some server (Win2k3/Win2k8 and VM Server) and host it there but with VM Server. (In both Fusion/Workstation).
An equivalent to Hyper-V. (Both Fusion and Workstation take advantage of type-2 hypervisor a for 64x VMs, neither do for 32 bit VMs. VMWare claims they're no slower as a result some benchmarks corroborate this assertion).
Ability to Share disks between multiple VMs. If I have a bunch of databases on a virtual disk and want them to appear on more than one VM I should be able to just attach them. (Available in both Fusion and Workstation)
(Nice to have) Support for multiple processors assigned to a VM (Available in both Fusion and Workstation).
Is there a VMWare guru out there who knows for sure that the above features are available on the other side?
Also the above has been free (as long as you have licenses for Windows machines), besides buying Fusion are there any other costs?
The end result of my research, thanks so much!
You can only create Linked clones and Full Clones (which are close to differencing disks) in VMWare Workstation (not Fusion). Workstation also has at better snapshot management in addition to other features which are difficult to enumerate. That being said Workstation is $189 (as opposed to $79) and not available on OS X. In addition Fusion 1.1 (current release) has a bunch of display bugs on OS X 10.5 (works well on 10.4). These will be remedied in Fusion 2.0 which is currently in (RC1). I'll probably wait until v2.0 comes out and then use both Workstation/Fusion to provision and use these VMs on OS X.
I've not used Fusion, just workstation and server
1) Yes, you can create a linked clone from current vm state, or from a saved state (snapshot) in VMware Workstation
2) Yes, revert to snapshots
3) There's a number of different network setups, NAT's one of them
4) VMware virtual machines created with VMware Fusion are fully compatible with VMware’s latest products.
5) ?
6) You can add pre-existing to disks to other vm's
7) Yup, you create multi-cpu vm's
Workstation costs, but VMWare Server is free
It doesn't have #1, at least.
VMWare server is free, but only allows for one snapshot, a serious deficiency. VMWare Workstation allows multiple snapshots and can perform most of the same functionality.
VMWare has a Hypervisior which is equivalent to Hyper-V in Virtual PC.
You can not share a VM that was created in Fusion with Windows VMWare Server (free version) you'll need the paid version to be able to share amongst both.
I'd also take a look at Sun's xVM VirtualBox for Mac. It runs Windows XP and Vista quite swift on my Mac.
1 and 2) VirtualBox has snapshots that branch off from the base VM like a tree. You can revert to any previous snapshots and name them.
3) It has NAT support and bridged networking like the VMWare and Microsoft products.
4) There is no server version of VirtualBox, but I know it shares an engine with Qemu, so it may be possible to host your VBox images on Qemu.
5) VirtualBox does have a hypervisor if your Mac has VT-x enabled.
6) Sure, you can add existing disks to other VMs. But you can't run the same disk in multiple VMs at once. (Isn't that a restriction of all virtualization hosts, though?)
7) No. VirtualBox will give each image one CPU and spread them out.
