RancherVM Live Migration with Shared Storage -- Demonstration

RancherVM Live Migration with Shared Storage -- Demonstration

Published Jun 1, 2018

With the latest release of RancherVM, we've added the ability to schedule virtual machines (guests) to specific Kubernetes Nodes (hosts).

This declarative placement (in Kubernetes terms: required node affinity) can be modified at any time. For stopped VMs, no change will be observed until the VM starts. For running VMs, the VM will enter a migrating state. RancherVM will then migrate the running guest machine from old to new host. Upon completion, the VM returns to running state and the old host's VM pod is deleted. Active NoVNC sessions will be disconnected for a few seconds before auto-reconnecting. Secure shell (SSH) sessions will not disconnect; a sub-second pause in communication may be observed.
