我在XP系统安装了虚拟机VMware Workstation.通过Virtual machine 创建完windows98虚拟机后，按start this virtual machine按键老是提示以下错误：
Not enough physical memory is available to power on this virtual machine. To fix this problem decrease the memory size of this virtual machine to 12 megabytes, or adjust the additional memory settings to allow more virtual machine memory to be swapped.
If you were able to power on this virtual machine on this host computer in the past, try rebooting the host computer. Rebooting may allow you to use slightly more host memory to run virtual machines.
