The Master-VM framework enables a user to use a single virtual machine (“Master-VM”) from an online source to set up a hands-on lab for learning about a specified application. For example, the user can use the Master-VM to set up a hands-on lab to learn about Hadoop technology. The hands-on lab can include a collection of VMs associated with Hadoop technology framework and various training materials such as documentations, training videos, lab exercises associated with Hadoop technology. The Master-VM can deploy the collection of VMs associated and allow the user to access, explore, evaluate or configure the Hadoop technology framework using the multiple VMs and the training materials. ## Claims ### Claim 1 A computer-implemented method, comprising: generating a master-virtual machine (VM) installation file for installing a master-VM on a client device; adding an application package to the master-VM installation file, wherein the application package includes a collection of VMs corresponding to an application, wherein a first VM of the collection is different from a second VM of the collection, and wherein at least one VM of the collection has a first role and another VM of the collection has a second role; adding, to the master-VM installation file, data files that provide information regarding the application; configuring multiple components of the master-VM to install the collection of VMs at a host server device and provide access to the data files; adding an installer application to the master-VM installation file that is configured to install hypervisor application at the host server device; installing, using the master-VM installation file, the master-VM at the client device; installing, from the client device and by the master-VM, the collection of VMs in the master-VM installation file at the host server device; receiving, at the client device, a user request to access the application at the host server device; and providing access to the application at the host server device via the master-VM at the client device. ### Claim 2 (depends on 1) The computer-implemented method of claim 1 further comprising: storing the master-VM installation file at the host server device or the client device. ### Claim 3 (depends on 1) The computer-implemented method of claim 1 further comprising: generating, at the client device, information regarding the data files stored at the client device, the data files including multimedia content having information regarding accessing or configuring the application; receiving, at the master-VM and by a user, a request to access one or more of the data files; and providing, by the master-VM, access to the data files to the user. ### Claim 4 (depends on 1) The computer-implemented method of claim 1 further comprising: receiving, at the master-VM and by a user, a request to access the collection of VMs; and providing, by the master-VM, access to the collection of VMs. ### Claim 5 (depends on 1) The computer-implemented method of claim 1, wherein installing the collection of VMs includes: installing, by the master-VM and using the installer application, a first hypervisor software at the host server device. ### Claim 6 (depends on 1) The computer-implemented method of claim 1, wherein installing the master-VM includes: installing a second hypervisor software at the client device. ### Claim 7 (depends on 1) The computer-implemented method of claim 1 further comprising: installing an edge VM gateway at the host server device and the client device. ### Claim 8 (depends on 7) The computer-implemented method of claim 7, wherein the master-VM and any VM of the collection of VMs communicate with each other via the edge VM gateway. ### Claim 9 (depends on 7) The computer-implemented method of claim 7, wherein installing the master-VM includes: configuring a first network interface of the edge VM gateway at the client device to communicate with the edge VM gateway at the host server device, and configuring a second network interface of the edge VM gateway at the client device to communicate with a computer network. ### Claim 10 (depends on 1) The computer-implemented method of claim 1, wherein installing the collection of VMs includes: generating information regarding multiple types of installation of the collection of VMs, each type of installation specifying a type of configuration to performed for the collection of the VMs, receiving, from the user, a specified type of the multiple types as an input, and configuring the collection of the VMs based on the specified type. ### Claim 11 (depends on 10) The computer-implemented method of claim 10, wherein the multiple types include: a first type of installation, which indicates that none of the VMs in the collection of VMs are to be configured by the master-VM, a second type of installation, which indicates that at least some of the VMs in the collection of VMs are to be configured by the master-VM, and a third type of installation, which indicates that all of the VMs in the collection of VMs are to be configured by the master-VM. ### Claim 12 (depends on 10) The computer-implemented method of claim 10, wherein the multiple types include: a fourth type of installation, which indicates that the collection of VMs at the host server device are to be copied to another storage device. ### Claim 13 (depends on 1) The computer-implemented method of claim 1, wherein adding the application package includes: determining configuration information associated with the collection of VMs, wherein the configuration information includes at least one of a number of VMs to be required for the application, hardware specification for each VM, an operating system to be installed on each VM, a role of each VM, wherein the role is one of a master role or a slave role. ### Claim 14 A computer-readable storage medium storing computer-readable instructions, comprising: instructions for generating a master-virtual machine (VM) installation file for installing a master-VM on a client device;
