in es_ES locale the new VM dialog is messed up.
Verified in ovirt-engine-3.5.0-0.0.master.20140804172041.git23b558e.el6.noarch (rc1). The es_ES dialog `Nueva máquina Virtual` is displayed correctly, layout is nearly the same as the en_US l10n, no messed up inputs or labels comparing to en_US. See attached screenshot for details.

oVirt 3.5 has been released and should include the fix for this issue.
