laravel homestead安装过程中，在vagrant up命令时出错，大家有遇到同样问题么？
laravel版本：5.1
homestead版本：0.2.6，最新的0.2.7下载后说box文件有错误，不能使用。
在网上搜索了一下，一般说是virtualbox的bug，
我试了以下四个版本
4.3.28；
4.3.26；
4.3.24；
4.2.30；
都出现同样的错误，错误信息如下：

 --------------------------------------------
$ vagrant up
Bringing machine 'default' up with 'virtualbox' provider...
==> default: Importing base box 'laravel/homestead'...
==> default: Matching MAC address for NAT networking...
==> default: Setting the name of the VM: homestead
==> default: Clearing any previously set network interfaces...
There was an error while executing `VBoxManage`, a CLI used by Vagrant
for controlling VirtualBox. The command and stderr is shown below.

Command: ["hostonlyif", "create"]

Stderr: 0%...
Progress state: E_FAIL
VBoxManage.exe: error: Failed to create the host-only adapter
VBoxManage.exe: error: Code E_FAIL (0x80004005) - Unspecified error (extended info not available)
VBoxManage.exe: error: Context: "int __cdecl handleCreate(struct HandlerArg *,int,int *)" at line 66 of file VBoxManageHostonly.cpp

大家怎么解决的？
