Hi All,
Okay. Now I am confused.
I have a bunch of virtual machines running under Virtual Box 3.2.12. I want to run them under KVM and drop Virtual Box from these systems.
Supposedly "qemu-img convert" now supports direct conversion from vdi to whatever KVM uses. So I fired up the man page and got really confused. Then I fired up Google and got worse confused.
Might I impose on some kind individual to write down a sample run string that would show me how to do this?
Many thanks, -T
Is it as easy as?
qemu-img convert -f vdi oldImage.vdi -O qcow2 newImage.qcow
Do I need a ton of disk space to go to a full hard drive then back to a small virtual hard drive?
Do I need the Virtual Box XML file for anything or just the VDI?
Many thanks, -T

Yup! I don't use the -f option. qemu-img auto detects the input file format.

Please elaborate on the above points. I don't understand what you are trying to do.

The XML file contains all the Virtual Box machine settings -- hard drive type and size, mouse, floppy drive, number of cores etc.. I was unclear if 'qemu-img convert" needed to know any of this or did it just need the raw hard drive.
What I am trying to do is ween myself off of Virtual Box. And now that Xfce 64 bit is getting close, I am about to pull the trigger.
Thank you for the help!

You just need the raw hard (virtual) drive filename. Beware, if you have taken snapshots in your VB vdi disk. You may need to "merge" the snapshots (if that is possible) before you convert. One my engineer had given me a VDI file insisting that he had implemented what I had asked him to do - he did not disclose he had been taking snapshots after every bit of configuration. Upon conversion I could not see any of his work!

Great. I have been using KVM since 2009, to create small appliances and deploy in production.
I use the kvm CLI tool - nothing fancy like virsh or virt-manager yet. The VMs are started and stopped using init scripts.
