System and method for performing efficient failover and virtual machine (VM) migration in virtual desktop infrastructure (VDI)
View Patent ↗Certain aspects direct to systems and methods for performing virtual machine (VM) management to provide efficient user login and minimize resource usage. The system includes a virtual machine server storing a hypervisor and multiple VMs, and a virtual desktop controller. The virtual desktop controller is configured to control the virtual machine server to execute the hypervisor, and to execute at least (M+S) instances of the VMs on the executed hypervisor. When the virtual desktop controller detects a current number X of the executed VMs on the executed hypervisor, the virtual desktop controller determines whether X is greater than M. If X is greater than M, the virtual desktop controller controls the virtual machine server to execute some instances unexecuted VMs as the spare VMs on the hypervisor, such that S instances of the spare VMs are available to provide efficient user login.
