[one-users] Is it OK for VM migration between two physical hosts when the home folders of these two hosts are different?

[Carlos Martín Sánchez]

Hi,

The oneadmin home is not relevant, what is required is that the datastores
are mounted in the same location [1]. DATASTORE_LOCATION is defined in
oned.conf, and by default it is /var/lib/one/datastores.

Regards
