The existing migration method for existing VMware VMs is not realistic. Currently existing VMs on a VMware host require exporting as an OVF/OVA, then importing into Cloudstack as a template, then deploying within CS again. This method is also unstable as many migrations fail with a BSoD or Kernal Panic.
If this is the only way to migrate then Cloudstack is going to have a big problem trying to get people with medium to large existing infrastructures to switch over to Cloudstack.
I would like to request a feature/method that would allow for a streamlined migration process. I believe this will increase adoption by small, medium and Enterprise class businesses tremendously.
I would like to see Cloudstack, through a GUI Based wizard (prefered) or at least CLI/API scripting process which can look at attached vCenter cluster or host for existing VMs and perform the following.
1. Lists Existing VMs on a Cloudstack attached vCenter cluster or host.
2. Allow admin to select the VMs they want to migrate into cloudstack zone and assign each vm to a user or group account in Cloudstack.
-Click migrate button
Two possible processes below
3.a A process starts to snapshot the existing server, renames and copies the VM files to Cloudstack format and places in CS primary storage. Continue to #4
3.b A process starts that initiates Storage vMotion on the existing server, renames the VM files to Cloustack format and places in CS primary storage.(Could be live migration option?) Continue to #4
4. Cloudstack then updates its database to reflect the new inventory.
I am sure my process is missing a bunch of things, but in general this should be possible I think. We should also develop the same feature for other CS supported hypervisors as well.
I wish I was a programmer so I could help with this.
Thank you very much!
