Kvm migration problem

Kvm migration problem

[Wagner, Kai]

Hey,
im from germany and new in kvm. I'll tried the how-to's from your page to migrate an windows vmware .vmdk to a kvm image. I'll also tried so start the kvm with "kvm -drive file ..." but that also wont work. I'll hope you could get me an answer how to migrate my vmware .vmdk to an working kvm img.

edit: If i want to start the converted img it always told me, that there is problem with the img.

Greetings
Kai

Do you mean the lower paragraph of this one?

Have you used the right .vmdk? Sometimes VMware creates a small text 
file containing only a few hundred bytes of text describing the actual 
disk. If you convert (or use) this file, it will create (or use) an 
empty disk image. If "$ file foo.qcow2" reports something with "size 0 + 
0", you should look into the original .vmdk file, find the real file 
name and convert (or use) this one.

Can you tell us the actual message?

HTH,

Probably yes. Windows is very picky about some disk internals, so you 
may look for hints on moving physical hard disks with Windows on it on 
the Web. For the Windows installation moving from VMware to KVM looks 
like you moved the hard disk into another computer.
