Abstract: Implementations of the disclosure provide for secret keys management in a virtualized data-center. In one implementation, a system is provided. The system comprising a memory to store secret key data and a processing device coupled to the memory. The processing device is to detect activation of a hypervisor on a host system. A request is received from a virtual machine (VM) associated with the hypervisor to access a data storage domain. A secret key providing authenticated access to a data storage device domain is registered to the hypervisor. The secret key includes a universally unique identifier (UUID). To register the secret key, the processing device is to store a data structure indicating an association between the UUID of the secret key and the hypervisor in a volatile memory associated with the processing device. Thereupon, the UUID of the secret key is transmitted to the hypervisor associated with the VM.

Abstract: Implementations of the disclosure provide for live storage domain decommissioning in a virtual environment. A method of the disclosure includes identifying, by a processing device, a storage domain to decommission from a storage system. The storage domain comprises a plurality of disk images. It is determined whether the disk images are associated with a virtual machine. Thereupon, the disk images are hot-unplugged from the virtual machine. Responsive to detecting that the disk images are unplugged from the virtual machine, the disk image is deleted from the storage domain and the storage domain is removed from the storage system.

Abstract: A processing device identifies a failure with at least one physical storage device of a first set of physical storage devices accessible to a virtualized environment via a logical storage domain. The logical storage domain has an assigned address. The processing device identifies a backup of the first set of physical storage devices. The backup includes a second set of physical storage devices. The processing device also prevents the virtualized environment from accessing the first set of physical storage devices. The processing device associates the second set of physical storage devices with the logical storage domain to cause storage access of the virtualized environment to be redirected to the second set of physical storage devices via the logical storage domain.

Abstract: Systems and methods for managing virtual machine templates. An example method may comprise: identifying, by a computer system, a virtual machine snapshot represented by a volume chain comprising one or more copy-on-write (COW) volumes; and creating, based on the virtual machine snapshot, a virtual machine template represented by a new COW volume, wherein the new COW volume comprises data from the COW volumes of the volume chain.

Abstract: An apparatus receives virtualization manager indication of a capability selected from a virtualization manager capability subset. The apparatus receives non-virtualization manager indication of a selected capability not in said subset. The apparatus passes virtualization manager indication of a result of the capability selected from the subset. The apparatus passes non-virtualization manager indication of a result of the capability not in said subset.
