1. A method for coordinating, in a storage management system, between a restoration of a virtual machine and a virtual-machine-file-relocation operation, the method comprising: copying, by a media agent, a first set of data blocks from a backup copy of data associated with the virtual machine to a read-cache associated with the media agent, wherein the backup copy is stored on a secondary storage device and comprises one or more configuration files and one or more virtual disks, and wherein the first set of data blocks is based on a profile of the virtual machine; launching execution of the virtual machine on the host computing device, based at least in part on the first set of data blocks; copying, by the media agent, a second set of data blocks from the backup copy to the read-cache, wherein the virtual-machine-file-relocation operation comprises a logical transfer, according to a relocation sequence, of the backup copy of data associated with the virtual machine to a destination on a primary storage device that is in communication with the host computing device, and wherein the second set of data blocks is based on the relocation sequence; while the virtual machine executes on the host computing device prior to the virtual-machine-file-relocation operation, serving, by the media agent, a read request for a data block, wherein serving the read request comprises: (i) if the requested data block is not found in the read-cache, copying, by the media agent, the requested data block from the backup copy to the read-cache, and (ii) transmitting, by the media agent, the requested data block from the read-cache, wherein the read request is served at a higher priority than copying the second set of data from the backup copy to the read-cache; and while the virtual machine and the virtual-machine-file-relocation operation execute concurrently on the host computing device: (A) serving, by the media agent, a read request for a data block, wherein serving the read request comprises: (i) if the requested data block is not found in the read-cache, copying, by the media agent, the requested data block from the backup copy to the read-cache, and (ii) transmitting, by the media agent, the requested data block from the read-cache, and (B) copying, by the media agent, a third set of data blocks from the backup copy to the read-cache, wherein the third set of data blocks is based on the relocation sequence of the virtual-machine-file-relocation operation, and wherein the read request is served at the same priority as copying of the third set of data blocks.
