How to solve the error "Code: 0x0000000A" while installing Windows 8 Developer Preview?

Question

I am using VirtualBox 4.1.2 for Windows hosts

Here is the configuration used for the virtual machine:

When I start the virtual machine some files are loaded and there is a progress-bar Loading Files... then after it is finished there is a black screen for some 30 or 35 seconds.

Then comes the splash screen Windows Developer Preview which is displayed again for some 30 or 35 seconds.

After that there is a blinking message which says

Your computer needs restart
Please hold the power button
Code: 0x0000000A
Para
...some values in Hexadecimal...

It blinks for some time then comes to a halt.
Here is a screenshot.

How do I get it to work?
Where is the problem?
Is it some problem with the RAM alloted to Windows 8 Developer Preview?

I am using this guide for reference.

Edit: Another guide which can be used for reference.

Windows 8 需要硬件支持虚拟化，错误0x0000000A似乎与缺乏上述内容有关：虽然我看到您的 VT-x/AMD-V 加速已启用，但我建议您仔细检查它（特别是，验证该功能在 BIOS 设置菜单中启用）。
