- tw04 10y agoThose are all absolutely valid options, none of those "have this ability". Nothing in the open source world currently matches NSX's ability to extend the network from on-prem to the cloud. I really wish they did, but it's not even a discussion.
- ensignavenger 10y agoSorry, maybe I am misunderstanding what feature you are talking about. Al of the solutions mentioned are ones you can run on your own hardware, as well as their respective 'cloud' services, using the same APIs. Are you wanting some sort of live migration of vms between the two?
- caraboga 10y agoOpenstack doesn't have the in-product hooks to detect hardware failures on the host machine to prompt an automatic, vm-state preserving live migration to other hosts. If you are using kvm w.r.t. openstack, the vm machine actually is suspended by way of acpi, then moved, then unfrozen again. VMware doesn't do that in vmotion. All your problems with clock skew, dropping of network traffic are lessened (they don't completely go away) with vmotion.
