>From the cloudstack installation guide, I know that I should have a "clean hypervisor host" when deploy cloudstack. But I think that is ideally. sometimes, we need to migrate host with existed VMs into cloudstack in practice. of course, we can export the VMs from hypervisor and then import it after deploy cloudstack complete. It is very inefficient. I have thought about this issue for a long time. I found network and storage is the biggest barrier for migrating. Existed VMs may use local storage. then can not put it into a zone only with share storage. we can also not assign a proper network to it since we need to keep the ip unchanged. But I think we can work around these issue. and I make a simple test to add a host with some VMs into cloudstack. The happen after that surprise me. Cloudstack connect to the host successfully and I can access all existed VMs in the host as normal. Did it indicate that it is possible to migrate host with VMs into cloudstack? If not, would you like to tell me what would happen and what risk should I take.
