Vagrant - up時出現error--vm內存不足

問題

退出VM，再進入時，畫面顯示

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

Command: ["modifyvm", "74e2a381-79e2-43c0-a75b-a3cec691babcdefg", "--natpf1", "delete", "ssh"]

Stderr: VBoxManage.exe: error: Code E_FAIL (0x80004005) - Unspecified error (extended info not available)
VBoxManage.exe: error: Context: "LockMachine(a->session, LockType_Write)" at line 529 of file VBoxManageModifyVM.cpp

原因

內存不足，vm冥想中
此時ssh也連接不上，reload也無法啓動

解決

通過virtualbox的管理工具關閉
管理者模式啓動Powershell

PS C:\Program Files\Oracle\VirtualBox>  .\VBoxManage.exe controlvm 74e2a381-79e2-43c0-a75b-a3cec691babcdefg poweroff
0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%

 vagrant up

可以正常重新啓動
