VM mobility between G8’s online #1140

Open wvandebroeck opened 6 years ago

wvandebroeck commented 6 years ago

Motivation

When low latency links are available we should provide the ability to move VM’s between G8’s.

Terminologies and Concepts

StorageVmotion and VMotion: https://docs.vmware.com/en/VMware-vSphere/6.0/com.vmware.vsphere.vcenterhost.doc/GUID-59C7D7FF-D17E-45BC-9145-06B2993880A2.html

Goals

Provide VM mobility to balance between clusters or moving workloads between G8's.

@grimpy Can we already move a vm from one cloudspace to another within the same environment?

grimpy commented 6 years ago

This is currently not possible yet. This requires assigning new private IP to a VM updating the ros of source and target to contain the new lease. In theory this can be done live by removing the nic from the original cloudspace bridge and adding a new nic to the new cloudspace, altough I doubt the guest OS will request a new lease on the added nic.

Offline is good enough for now.
