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. On 7/15/2013 9:08 AM, David Nalley wrote: I agree with this statement. Configuration of EL6 or Ubuntu or even Windows image

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 an

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. -jason On 7/15/2013 9:04 AM, Kirk Jantzer wrote: It is my belief that the cloud

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

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 cus

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? -jason On 7/14/2013 12:18 AM, Nils Vogels w

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. Nils On Sun, Jul 14, 2013 at 7:50 AM,
