How to migrate instances of OpenStack to Cloudstack.
Hi,all:
Is there any method to move instances from Openstack to Cloudstack? Both
OS and CS are using KVM as hypervisor.
Best regards.

We were able to get vmware images running in cloudstack with kvm hypervisor using qemu-img, but we also had to add the step of going in using a recovery image to switch all the disk lables from sdx to vdx since that's how they were being referenced once we switched hypervisors.

1 out of 3 qemu-img or vhd-util conversions usually produce a vm that is
corrupt or won't boot or that requires a ton of work to fix up. This is
at least my experience.

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.

That's because you shouldn't really be importing/exporting between clouds.
The best way to avoid any issues would be to have your instances built from
from a clean ISO install and then have them run post scripts or via a
config manager (puppet, chef, etc...). This can be achieved in both Windows
and Linux instances and will give you the most flexibility between any IaaS
provider, hardware of cloud.

Unfortunately that's not the case. I've had numerous issues
importing/exporting vm imagery from clouds running different
hypervisors. Importing/exporting from the same hypervisor type is fairly
straight forward.

It is my belief that the cloud is the IaaS and that the applications that
run on the cloud should be built for failure of the IaaS: they
(instances/applications) should be rapidly deployable. So, it shouldn't
matter what cloud product (openstack/cloudstack/vmware/aws/etc...) you
provide to your customers, they should be able to redeploy their
application whereever they go or are given for IaaS.

This is a VERY high level of the steps, dealing with different
Hyper-visors will produce varying results.
Is there a low level guide to importing/exporting imagery between kvm,
xen and vmware?
Something concise enough to work well with any cloud?

Hi Tao Lin,
Currently, the only way known to me is
1) Stop the instance in OpenStack
2) Import the instance as a template
3) Create a new instance, based on that template
4) Run the new instance in CloudStack
5) Discard the OpenStack instance
HTH & HAND.
