> Hi Paul
> I posted a query to Ironic which is related to this discussion. My thinking was I want to ensure the case you note here (1) " a tenant can not read another tenants disk......" the next (2) was where in Ironic you provision a baremetal server that has an onboard dish as part of the blade provisioned to a given tenant-A. then when tenant-A finishes his baremetal blade lease and that blade comes back into the pool and tenant-B comes along, I was asking what open source tools guarantee data destruction so that no ghost images or file retrieval is possible?
Is that really a path worth going down, given that tenant-A could just
drop evil firmware in any number of places, and thus all tenants afterward
are owned anyway?
