<div dir="ltr">Hi Naveed,<div><br></div><div>I don't think it's a good idea to suspend/pause. If you want to keep the state of the VM then have a look at the live migration capabilities of KVM. Our script is very simple and works for any VM without attached block storage. </div>
<div><br></div><div>Here goes the little script. Keep in mind it's something very simple. </div><div><br></div><div><a href="https://gist.github.com/diegoparrilla/6288e1521bffe741f71a">https://gist.github.com/diegoparrilla/6288e1521bffe741f71a</a></div>

To be honest I would love to have a better way to do it, but this is how we do. We have developed a tiny script that basically performs the following actions:</div>
<div class="gmail_extra"><br></div><div class="gmail_extra">1) Take a snapshot of the VM from the source Private Cloud</div><div class="gmail_extra">2) Halts the source VM (optional, but good for state consistency)</div>
<div class="gmail_extra">
3) Download the snapshot from source Private Cloud</div><div class="gmail_extra">4) Upload the snapshot to target Public Cloud</div><div class="gmail_extra">5) Start a new VM using the uploaded image in the target public cloud</div>
<div class="gmail_extra">6) Allocate a floating IP and attach it to the VM</div><div class="gmail_extra">7) Change DNS to point to the new floating IP</div><div class="gmail_extra">8) Perform some cleanup processes (delete source VM, deallocate its floating IP, delete snapshot from source...)</div>
<div class="gmail_extra"><br></div><div class="gmail_extra">A bit rudimentary, but it works if your VM does not have attached volumes right away.</div><div class="gmail_extra"><br></div><div class="gmail_extra">Still, I would love to hear some sexy and direct way to do it.</div>
