Hiya,
Yes i can choose the storage domain, but I cannot force the host that is
to be used for creating it. Even with 1Gbit network, creating a 80GB
disk / 40 GB disk is still significantly longer process than actually
required when doing a "dd" of /dev/null over the network.
Is it possible to manually change who is SPM master, create the
disks/VMs required, and change it back ? How would that change affect
the running VMs / would they try to migrate to the other HV ?

Hi Alex,
The storage domains are part of the Data Center, and should not be
related to clusters.
Clusters are used for migrating VMs, which are the qemu processes,
between hosts.
Disks are created on the storage domains regardless to clusters.
The host which write the data in the storage domain to create the disk
is the SPM.
You should have only one SPM in each Data Center (You can spot which
host is your SPM by looking at the SPM column in the hosts tab)
When you create a disk you should be able to choose the storage domain
which you want the disk to be created on.

Maor
