Running virtual machines on USB stick?

Has anyone any experience on running virtual machines on an USB stick? Today, I have several development servers running in virtual instances on my external eSata 7200rpm 2.5" disk. However, I have been thinking on instead putting my virtual disks on an USB instead. The sizes (I need 30GB+) and prices has come to a point where it seems...

Unable to understand a statement about compilers' optimization

I am interested in optimization at runtime by a VM and at compile-time. I have had the idea that optimizations are most efficient and easiest at compile-time. However, my thought seems to be false in certain circumstances. This is evident in Steve Yeggie's statement quoted by Daniel [O]ptimization is often easier when performed at r...

How do polymorphic inline caches work with mutable types?

A polymorphic inline cache works by caching the actual method by the type of the object, in order to avoid the expensive lookup procedures (usually a hashtable lookup). How does one handle the type comparison if the type objects are mutable (i.e. the method might be monkey patched into something different at run time). The one idea I'v...

F1 help in XBAP

Hi, I understand Stack Overflow is the place for really specific questions that only a couple of people would be interested in so here goes... I have an application which is deployed as an XBAP which contains some embedded WinForms popup modal dialogs - it's a combination of legacy code and some new stuff and we don't have time for a co...

debugging code run in a virtual machine using the host

Is there a debugger which works from a virtual machine's host? That is, instead of using interrupts inside the machine, I expect this debugger to recognize the virtual machine's OS routines, memory locations etc, and to recognize when the OS is launching a certian EXE. Then I want to be able to set hardware-like breakpoints per process ...

Non-Proprietary Virtual Image Clients?

Hi, Just to ask if there are any non-proprietary virtual image clients available, i.e. an application capable of running .vhd and/or .vmdk based virtual images? I have searched online, but have not been able to find any. Note, I am actually looking to avoid using the bloated VMware Server 2.0, with its web interface and resource hun...

host and kvm/qemu guest shared partition

¿It's possible to share a partition (or lvm volume) and using it at the same time between the host and the guest virtual machine? For example, if you have the /home in the /dev/sdf2 partition, use it inside the otherdistro vm and work at the same time, also. Thanks. ...

Compressed images on VMWARE

I know the difference between sparse and compressed images and I think that compressed images is better to move images from a central repository to a Hypervisor. More over, vmdk (Compressed) is defined like the standard disk used in OVF specification. More over, other hypervisor like virtualbox supports this vmdk compressed format. My...

Can you set up Visual Studio to deploy to a Virtual Machine?

Hey SO: I have a virtual machine running windows 2003 server. It is on a separate machine on the network to reserve computer resources on my dev machine. Is it possible to configure visual studio 2008 so when I click "deploy" it will deploy the solution to the virtual machine instead of my development machine? Edit I should note that ...

Maybe i should get time from external location so it would be correct even though i regularly pause my...

Lots of browser tabs with java applet causes OutOfMemoryException

I have an applet that consome quite a lot of Memory. If a user opens multiple tabs with a webpage that has the applet, they get an OutOfMemoryException. This can be explained by the fact that browsers use just one instance of a virtual machine. Is there any way I can prevent this? The OutOfMemoryException can't really be caught, since i...

VS2010's WPF renders poorly inside a Windows7 VM?

Kevin Hoffman this morning reports that: When put under a virtual machine running Windows 7, VS2010 fails to render things, borders disappear, windows become unusable and the experience is downright awful. On the other hand, when you run VS2010 "bare metal" with no virtualization between it and your video card, everythi...

Can a virtual machine be implemented as a neural network?

Disclaimer: I'm not a mathematical genius, nor do I have any experience with writing neural networks. So, please, forgive whatever idiotic things I happen to say here. ;) I've always read about neural networks being used for machine learning, but while experimenting with writing simple virtual machines, I began to wonder if they could b...

What does the Flash VM use under the hood for drawing?

In windows--what does Flash use under the hood? It's a relatively simple question which I can never find the answer to. Is it GDI (for windows VM implementations) or something else? You don't need to go into any of the new GPU acceleration features of Flash. I just really want to the inner workings because it's NEVER discussed. ...

Is the CLR a virtual machine ?

Hi, I read a book which referred .net CLR as virtual machine ? Can anyone justify this ? What is the reason we need the concept of virtual machines on some development platforms ? Isn't it possible to develop a native framework [one without virtual machine] that is fully object oriented and as powerful as .net ? The book which refers ...

Virtual Machines and Handling Memory and System Calls

This is a homework problem that I have. I have been doing some research and couldn't find much. I did find a powerpoint but could not make much sense of it due to lack of text. http://xen.org/files/xensummit_tokyo/19_KoichiOnoue_en.pdf (Specifically, what is gPa and hPa?) I was wondering if anyone could point me in the correct directi...
