There was an error while executing `VBoxManage`, a CLI used by Vagrant
for controlling VirtualBox. The command and stderr is shown below.

Command: ["startvm", "152cca03-0b0a-4e57-b501-b694821a2629", "--type", "headless"]

Stderr: VBoxManage.exe: error: The virtual machine 'homestead-7' has terminated unexpectedly during startup with exit code -1073741819 (0xc0000005).  More details may be available in 'C:\Users\ZhangY\VirtualBox VMs\homestead-7\Logs\VBoxHardening.log'
VBoxManage.exe: error: Details: code E_FAIL (0x80004005), component MachineWrap, interface IMachine

通过VBox直接启动虚拟机也失败：
