Abstract
A mechanism for virtual machine (VM) boot speed-up by clock acceleration is disclosed. A method of the invention includes detecting that a VM managed by a hypervisor of a host machine is starting a boot up process, modifying a rate of a clock of the VM to speed up the boot up process, determining that the boot up process of the VM is complete, and returning the rate of the VM clock to a normal operational rate that is slower than the rate of the VM clock during the boot up process.
