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.
I do not believe so! Not both at the same time...
Do folks on the mailing can read;
http://forums.virtualbox.org/index.php
???
Sure, everybody can! But: I don't know, if the really do read both, I, for
example, rarely look into the forum...
I have a problem running;
$ VBoxManage modifyvm "Debian Lenny Server" --hda "Debian_Lenny_Server.vdi"

This is a SATA HD
--hda is an IDE disk, and as you state yourself, that you have a SATA disk in
the image, you need to specify the name of a SATA disk. You need to chek the
user guide, I'm offline...
I posted my problem on the said forum. Do I need repeat it on this mailing
list?
If you want to reach the users of the forum as well as the readers of this
mailinglist, then, yes, you need to repeat it here...

Subject: Re: [vbox-users] Convert KVM to VirtualBox
W.r.t. 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...

Hi Matthias,
Build vbox? No need to! Just install vbox!
Whether install VBox on Fedora 12 (the host of the running Virtual Machine)?
Can VBox and KVM coexist running side by side?
Others noted with thanks. My purpose to convert KVM VM to VBox VM is solely to
learn this technique. Particularly I'm interested to learn dumping a running
physical box as VM. Personally I prefer clean installation.
B.R.

Hi Matthias,
Thanks for your advice.
I'm prepared to build VBox on the same PC which is now running KVM and Fedora
12 64bit as host. Because Fedora 12 freezes frequently while browsing
Internet. Adding to it I can't make libvirt to allow VM to work on sound.
Therefore I'll wipe out the PC and build VBox on it running Debian 5.0.4 64bit
as host.
Build vbox? No need to! Just install vbox!
Still, you might encounter difficulties with different hw-abstraction layers
(aka different
drivers!) between kvm and vbox
Please explain in more detail. TIA
Every virtualization is an abstraction of some specific hardware! KVM does NOT abstract to a
common, specific model, it simply uses, what's there! So, you need to use the device driver for the
physically available network-interface, and not a "virtualized", "generic"
interface.
Vbox has a specific set of hardware elements, that are "emulazed", VMware has a different
set, and therefore moving a guest from one virtualization to a different one requires different
drivers in the guest. That get's specifically nasty, once the interface for your boot-disk changes
(IDE <-> SCSI <-> SATA). And it even gets more complicated, once you use a
virtualization, that doesn't abstract the hardware (like KVM), but simply manages (limits, controls)
access to the real hardware...

Qemu-img should be part of vbox, and should be documented in the vbox user
guide...

Hi Karthik,
Thanks for your advice.
I found following doc on Internet;
How to Convert a KVM to a VDI
http://www.ehow.com/how_5856610_convert-kvm-vdi.html
However I read in another place saying running qemu-img to convert VM will be
easier. I'm now searching how to make it with qemu-img

Hi folks,
What will be the easy way converting KVM (qcow2) to VirtualBox (vdi)?
Can VMDK format (VMWare) works on VirtualBox ?
Your question sounds similar to trying to open Windows Visio drawings
file in OOo Draw .
That is, if vmdk format is openly available, then i think, it should
be possible.
Not sure. But, i wonder the kind of efforts would be required to design it ?
