[pve-devel] [PATCH manager v3 2/5] bulk migrate: improve precondition checks

[Dominik Csapak <d.csapak@proxmox.com>]

this now takes into account the 'not_allowed_nodes' hash we get from the
api call. With that, we can now limit the 'local_resources' check for
online vms only, as for offline guests, the 'unavailable-resources' hash
already includes mapped devices that don't exist on the target node.

This now also includes unavailable storages on target nodes.
