Hi Matthias,
Thanks for your advice. This virtual machine is for testing only; CPU - AMD Phenom II X4 955 RAM - 8G DDR3 1333 dual-channel Host - Fedora 12 64bit VirtualBox-3.1-3.1.4_57640_fedora12-1.x86_64 > But, I assume, they can co-exist, but I guess, KVM and VBox can NOT run simultaneously, as > both would require exclusive access to the CPU-s virtualization-extensions. I have VBox installed. It is now running. After the completion of building its VMs, I'll check whether they can run simultaneously. Do folks on the mailing can read; http://forums.virtualbox.org/index.php ??? I have a problem running; $ VBoxManage modifyvm "Debian Lenny Server" --hda "Debian_Lenny_Server.vdi" Select all Expand viewCollapse view Sun VirtualBox Command Line Management Interface Version 3.1.4 (C) 2005-2010 Sun Microsystems, Inc.

KVM and VBox running side by side... I've never tried it (as for me, KVM is still playgrond, and not yet DC-ready, and has a couple of deficiencies, like: It's missing all resource-management stuff, that for example Solaris offers, or that vbox or Xen or evem VMware offers: Secure separation of resources. With KVM, there is no such thing, as it doesn't provide a clean and separable "management" layer, instead it's using a standard and "normal" Linux. Sadly in that Linux, there no finegrained resource-managment like in Solaris, therefor limiting one guest and controlling it is tedious...). But, I assume, they can co-exist, but I guess, KVM and VBox can NOT run simultaneously, as both would require exclusive access to the CPU-s virtualization-extensions... And, the question of P2V-tools is still a work-in-progress, the only quite-well working tool is a VMware tool, designed to generate VMware-compatible guests. I've not yet seen reliable general purpose tools for anything else...
