[ovirt-users] Unable to remove host (SQL error)

Hello, I'm unable to remove a re-installed host from oVirt 3.5 cluster. The engine.log states: 2015-04-26 21:19:27,795 ERROR [org.ovirt.engine.core.bll.RemoveVdsCommand] (org.ovirt.thread.pool-8-thread-43) [34db91ae] Command org.ovirt.engine.core.bll.RemoveVdsCommand throw exception: org.springframework.dao.DataIntegrityViolationException: CallableStatementCallback; SQL [{call deletevdsstatic(?)}]; ERROR: update or delete on table "vds_static" violates foreign key constraint "vds_static_vm_dynamic_m" on table "vm_dynamic" Detail: Key (vds_id)=(629ca86d-f6a6-4702-bf0f-182af3df3b8c) is still referenced from table "vm_dynamic".
