Abstract: An architecture for demultiplexing volumes in a storage device includes a virtual machine. A guest operating system is in the virtual machine. The architecture further includes a storage pool of virtual storage blocks and a hypervisor. The hypervisor is configured to organize the storge pool of virtual storage blocks into a plurality of virtual storage partition tables. Device addresses are assigned to the plurality of virtual storage partition tables. The plurality of virtual storage partition tables and the devices addresses are organized into a virtual storage device. The device addresses are presented to the guest operating system in the virtual machine.

Abstract: Controlling communications among secure virtual machines is achieved by introducing a time-expiring mutual TLS (transport layer security) certificate, also referred to as an mTLS certificate. The mTLS certificate is controlled by an mTLS certificate issuer on a secure virtual machine, which operates to attest a secure workload virtual machine. An mTLS certificate issuer is deployed on a secure virtual machine. The mTLS certificate issuer is attested to by the deploying trusted execution environment. Workloads on secure virtual machines are configured to use only mTLS certificates issued by an mTLS certificate issuer.

Abstract: A computer implemented method manages virtual disks. A number of processor units detects attachment of a storage to a host operating system. The number of processor units mounts the storage to a set of mount points. The number of processor units creates a set of virtual disks and assigning, by the number of processor units, the set of virtual disks to a guest in operation in which instructions for the operation are performed without interruption. According to other illustrative embodiments, a computer system and a computer program product for managing virtual disks are provided.
