Classification: CPC G | IPC G

Claim 10:
11. A non-transitory computer-readable storage medium including instructions that, when executed by a processing device of a host system, cause the processing device to:
generate, by the processing device of the host system, a virtual machine for execution of a workload, wherein the virtual machine comprises a nested container storage interface (CSI) driver included in an overcluster;
provide communication endpoints of an undercluster CSI driver of an undercluster residing on the host system to the nested CSI driver to enable transmission of commands from the nested CSI driver to the undercluster CSI driver;
convert, by the nested CSI driver, a first command received from the workload to a second command used by the host system, wherein the first command is a request to create or delete a persistent volume and the second command is a command to resize an existing persistent volume
send the second command to the undercluster CSI driver, wherein the undercluster is a first cluster management operator managing a cluster of physical computing resources that support the virtual machine, and wherein the overcluster is a second cluster management operator executing within the virtual machine; and
allocate a persistent volume on the host system to the virtual machine, wherein a capacity of the persistent volume is modified by a volume management component in view of the second command used by the host system.
