Abstract: One or more techniques and/or systems are provided for virtual machine rebooting. A host machine may host a virtual machine. Virtual machine reboot information, used to reboot the virtual machine in the event of a failure or restart of the virtual machine, may be identified (e.g., file system metadata buffers, a virtual non-volatile random access memory log, user data buffers, and/or data used to reboot the virtual machine such as to perform a reboot mounting operation and/or a reboot replay operation of a volume of data associated with the virtual machine). The virtual machine reboot information may be cached within relatively fast host memory of the host machine (e.g., instead of merely within a relatively slower hard drive or other storage device). In this way, the cached virtual machine reboot information may be quickly retrieved so that the virtual machine may be rebooted in a relatively shorter amount of time.
