Hyper-V Server on a Presario Notebook

I thought it would be neat to have Hyper-V Server on a notebook, with Windows 2008 SBS as a guest OS, and then load some more legacy OS'es to test a piece of software I was developing. I have a 1.5-year old Compaq Presario (Core 2 Duo) lying around and I used it.

I chose to install the Hyper-V Server clean before installing any guest OS'es. That went fine and trouble free. Not a squeak that the CPU was or was not suitable.

Then searched around and found that Hyper-V Manager was needed. I downloaded the version for Vista 32-bit. It installed fine. But it won't connect. Complained with the famous error:

You do not have the required permission to complete this task. Contact the administrator of the authorization policy for the computer XXX

Did some tedious preparatory steps as indicated in John Howard's blog. But I just did: 1) create the common user, 2) netsh advfirewall ... 3) DCOMCNFG on the client.

Hyper-V Manager now connects fine and I can install new virtual machines. But when I tried to Start one, I get another famous error:

'vm name' failed to initialize. (VMID 'vmid')

The virtual machine could not be started because the hypervisor is not running. The following actions may help you resolve the problem:

1) Verify that the processor of the physical computer has a supported version of the hardware-assisted virtualization.

2) Verify that hardware-assisted virtualization and hardware-assisted data execution protection are enabled in the BIOS of the physical computer. (If you edit the BIOS to enable either setting, you must turn off power to the physical computer and then turn it back in. Resetting the physical computer is not sufficient.)

3) If you have made changes to the Boot Configuration Data store, review these changes to ensure that the hypervisor is configured to launch automatically.


I went into my BIOS but could not find anything to turn on DXP or virtualization. Then Intel confirmed that my Intel® Core™ 2 Dual T5250 was not suitable for Hyper-V!!

What a waste of time

Well, I have an older Presario. It's a T5500 and according to Intel that has Virtualization Technology. It will take time to make that notebook available for Hyper-V.

Attack Lab - Level 5 explained

Image
Ning Wang has published a very good write-up (2022 update: web page is gone now) on his solutions to the Attack Lab from the CS:APP book. However, I thought his solution to Level 5 could do with a bit more elaboration for those who are struggling with this topic. First, it is necessary to understand what ROP requires. An essential component of ROP is good luck, lots of it. Without getting lucky, you may take more than 10 100  years to find a workable attack, if at all. This, the authors of CS:APP did not mention. I also could not comprehend the purpose this exercise is even given out as homework in CMU to be completed in a week (while there are tons of homework from other courses too), without an intensive course in Intel Assembler as a prerequisite. Level 5 requires the same general logic as Level 3, which can be summarized as (pseudo code): mov <cookiestring address>, %rdi //why? because touch3 is expecting it there call touch3 To achieve the above for Level 5, ...

Assembly version, File version, Product version

Image
If you are a .NET developer, Assembly and File version would be familiar to you. They can be set in the Designer UI (project Properties page, Application tab, Assembly I nformation button...) which basically updates appropriate attributes in AssemblyInfo.cs. Now, there is a less well known number - the Product version . It is not well documented and most developers ignore it altogether with no side-effects most of the time. However, it is an important number and it seems that, of the three, Product version is the most widely used. The three version numbers simply take the values you give them or: a. If Assembly version is not explictly specified, it takes the value of 0.0.0.0. b. If File version is not explicitly specified, it takes the value of Assembly version. c. If Product version is not explicitly specified, it takes the value of File version. In Windows Explorer of Windows XP and Server 2003, you can see from the properties of a file all three version numbers. In W...

Setting to English for the Xiaomi Wifi Router

Image
The Xiaomi Mi Wifi Router now is in English. If it boots up to a foreign language for you, this guide will help you to change it to English. It is best to connect to it via wired Ethernet for the first time. Otherwise, the default unsecured wifi SSID should be Xiaomi_C3C1 . Your IP should be in the subnet 192.168.31.x, and the router is at http://miwifi.com which the router will resolve to 192.168.31.1. The first screen you see will be the setting up of the wifi SSID and wifi password. The big blue button at the bottom is the Next button. The next screen sets up the router administrator password (second field). The first field is Home/Work/Custom. Click the big blue button to complete. At the main configuration page, look for the third item (Settings) on the top menu, and the orange option (System Status): The last option on the page is the language selection: Open the drop down to select English: The change will take place the moment you click English.
