无法创建Docker虚拟机

我以前使用过boot2docker,并且一切正常.现在,当我升级为使用Docker Toolbox时,无法创建新的虚拟机.

我什至无法导入与boot2docker一起使用的虚拟机.

尝试创建新计算机时出现此错误：

C:Program FilesDocker Toolboxkitematicresourcesresourcesdocker-machine.exe -D create -d virtualbox --virtualbox-memory 2048 default returned non zero exit code. Stderr: Converting from raw image file="stdin" to file="C:Usersdisk.vmdk"... Creating dynamic image with size 20971520000 bytes (20000MB)... Error creating machine: exit status 1 You will want to check the provider to make sure the machine and associated resources were properly removed.

当尝试导入boot2docker使用的旧虚拟机时,我得到了这个信息：

C:Userspmandayam>docker-machine create -d virtualbox --virtualbox-import-boot2 
docker-vm boot2docker-vm docker-vm 
Creating VirtualBox VM... 
Error creating machine: exit status 1 
You will want to check the provider to make sure the machine and associated reso 
urces were properly removed.

协助,不胜感激.

谢谢,
