virtualization

I would want to compile existing software into presentation that can later be run on different architectures (and OS). For that I need a (byte)code that can be easily run/emulated on another arch/OS ( LLVM IR? Some RISC assemby?) Some random ideas: Compiling into JVM bytecode and running with java. Too restricting? C-compilers available? MS CIL. C-Compilers available? LLVM? Can Intermediate representation be run later? Compiling into RISC arch such as MMIX. What about system calls? Then there is the system call mapping thing, but e.g. BSD have system call translation layers. Are there any

I'm trying to get started on libvirt with VirtualBox as a virtualization solution. I installed everything and VirtualBox itself is running when using their VBoxHeadless command. However, libvirt fails to connect to VirtualBox: # virsh -c vbox:///session libvir: error : could not connect to vbox:///session error: failed to connect to the hypervisor I could not find any hints in the libvirt documentation that point to whether I have to make any domain specific configuration before using virsh. Does anyone have a hint? Or even better, maybe a tutorial that works through the way of using libvirt,

Ok, I have the most recent version of virtualbox installed, my computer (HP) has an AMD A10, 64bit Windows 10 OS and 6Gb RAM. I created a virtual machine with Windows 7, there I wanted to create a new virtual machine (a VM2 in a VM1), but I cant run it because I have no virtualization enabled in the VM1. ok, so I checked the VM1 configuration and the virtualization is enabled in the virtualbox settings. I've tried with all the Paravirtualization interfaces and always having the Hardware Virtualization enabled (VT-x and AMD-V). I really don't know why this is happening if this is all suposed to

I'm currently experimenting with build script, and since I have an ASP.net Web Part under source control, my build script should do that at the end: Grab the "naked" Windows 2003 IIS VMWare or Virtual PC Image from the Network Boot it up Copy the Files from the Build Folder to the Server Install it Do whatever else is needed I have never tried automating a Virtual Machine, but I saw that both VMWare and Virtual Server offer automation facilities. While I cannot use Virtual Server (Windows XP Home :-(), Virtual PC works. Does anyone here have experience with either VMWare Server or Virtual PC

I have a set of C# (v2) apps and I am struggling with registry virtualization in Win7 (and to a lesser extent Vista). I have a shared registry configuration area that my applications need to access in HKLM\Software\Company... Prior to Vista, everything was just written to and read from that location as needed. The code appropriately detected failures to write to that registry key and would fall back appropriately (writing to HKCU instead and notifying the user that the settings they had applied would only affect the current user). In Vista, registry virtualization broke all of this because the

What I would like to do is create a clean virtual machine image as the output of a build of an application. So a new virtual machine would be created (from a template is fine, with the OS installed, and some base software installed) --- a new web site would be created in IIS, and the web app build output copied to a location on the virtual machine hard disk, and IIS configured correctly, the VM would start up and run. I know there are MSBuild tasks to script all the administrative actions in IIS, but how do you script all the actions with Virtual machines? Specifically, creating a new virtual

I want to know how parallel space https://play.google.com/store/apps/details?id=com.lbe.parallel.intl&hl=en is working. It is an app for logging in with another facebook, whatsapp etc account. You can find the detailed description in the play store link. I have looked at the folders that parallel space is creating using ES Explorer. They have created the following folder parallel_intl/0/ In this folder they have DCIM, Pictures etc folder. I logged in another whatsapp account using parallel space and they created the whatsapp folder at the following location parallel_intl/0/Whatsapp Is it

I can understand the benfits behind dockerizing stateless services, such as web servers, appservers, load balancers, etc... If you are running these services on a cluster of machines, it is very easy to move these containers around with low overhead. What I don't understand though is the purpose behind containerizing databases? databases are connected to a data volume that is persistent in a specific hard disk. Because of state, it is not easy, and not efficient to actually move the database container around. So can anyone see why dockerizing a database can be useful at all? "So can anyone see
