Hi Guys,

I have 2 nodes (prox-01, prox-02) configured in cluster:

Each server has local non-shared storage (prox-01 -> local-lvm-01, prox-02 -> local-lvm-02)

lvmthin: local-lvm-01
thinpool pvepool

When I'm trying to migrate (Migrate button) stopped VM I get error:

I have 2 questions:

1. How I can fix migration?
2. Why migration using public network instead of private?

Thank you.

How I can fix migration?

Use the same storage name in you config. "local-lvm"
Storage's are culster wide and not node specific.
You can restrict storages to nodes but if you have the same storage on different nodes you should use the same name.

Why migration using public network instead of private?

You can set the migration network in the datacenter.conf.
