Subject Re: 答复: Cloudstack and Disaster Recovery

Thanks, but that is not my main problem. My difficulties are more like:

- how do I dump metadata for cloudstack KVM guests that are not running? virsh dumpxml will
not work as the guests that are not running are not defined at all in libvirt (ie this will
not list them: virsh list --all)

- how do I make sure the proper IPs and networks will be in place in the DR site? I'd need
to recreate all the virtual networks and make sure there is a Virtual Router somehow working
and still aware of IP assignments etc.

I know that ideally DR should be done at application levels, but it's not what the customers
are asking. :-)
