[one-users] cold migration error with open-nebula 3.8.1

Wed Jun 12 05:32:12 PDT 2013

Hi

This may be a misconfiguration in KVM (checkpoint files, with wrong
ownership/permissions) or a problem with your datastores.

1.- Check your KVM setup, specially dynamic_ownership, user and group as
described in the KVM guide

2.- Check with a running VM:

virsh --connect qemu:///system save one-<id>
/var/lib/one/datastores/0/<vmid>/checkpoint

The path is for the defaults location, you may need to fix it. Check that
the checkpoint is properly generated

3.- There should be a transfer.0.migrate (the number could be 1,2...
depending on the number of hosts the VM has been running in). In that file
there should be MV commands.

Check that the MV commands make sense in your case and TM configuration
(e.g. if you are using a shared system datastore, it should be mounted on
both hosts...)

Cheers

Ruben
