Subject Re: How to migrate instances of OpenStack to Cloudstack.
Date Mon, 15 Jul 2013 16:08:04 GMT
I agree with this statement. Configuration of EL6 or Ubuntu or even
Windows image should be trivial given configuration management.

That said, I understand there are some situations where it isn't
practical, or config management isn't in use. The technical answer is:

For converting to/from KVM to to/from raw formats or VMDK qemu-img is
your friend.
For converting to/from VHD for xen, vhd-util is your friend, though
there are several other apps out there.
I have been in places where I had to use qemu-img to do conversions
rather than 'doing it the right way' and it's worked well. If I had
the option though, I think I'd have preferred to put config management
in place and do it in that manner.
