Woah... your comment is a little hard to understand.

Question 1) Can I handle more than 4 disks per VM in Hyper-V

Answer 1) No, Hyper-V supports up to 4 virtual or physical disks

Question 2) Can I use more than 192 VMs

Answer 2) No.

The question is pretty easy to understand?

Hyper V Server (Standalone product) has only two virtual IDE controllers so can i create say 4 server 2008 virtual machines only if i only have two ide controlers with two channels each not to mention the dvd drive which has to be attached via an ide channel.

Sorry, there was no punctuation in your question so I read it as one continuous string of "WHARGARRBBLLL".

There are two virtual IDE controllers per VM you create, not per Hyper-V server.

So just to be clear that is 4 total channels PER VM a maximum of 192 VMs for a maximum total of 768 IDE channels.

ah i see now, i had two vm's created thats why i had four channels :)

the mist has lifted haha :)

what do i do to add scsi hard drive to and existing vm

cheers mate
You have to use a SCSI virtual adaptor.

Highlight your VM in the Hyper-V Manager, go to "Settings..." on the right side, click the "Add Hardware..." option at the top, and choose "SCSI Controller".

I am sure you can figure it out from there.

Booting from SCSI devices is not currently supported in Hyper-V.

hi on the hyper v server do u know the cli syntax on how to change the resolution to 1024 x 768?
Hmm.. not sure on that one. Why are you managing the server from the command line? It is better off to enable remote management and then you can work on it from the GUI of another system with the Hyper-V manager.

Run these commands in order on your Hyper-V server to enable remote management.
netsh advfirewall set allprofiles settings remotemanagement enable 
netsh advfirewall firewall set rule group="Remote Administration" new enable=yes
netsh advfirewall firewall set rule group="Remote Desktop" new enable=yes
cscript %windir%\system32\scregedit.wsf /AR 0
cscript %windir%\system32\scregedit.wsf /CS 0
winrm quickconfig -q

Open in new window

Found it though, on Hyper-V server you have to modify the registry to change the resolution.

Here is a guide:

what command do i need to run
nostrasystemsAuthor Commented:
i can do everything in hyper v manager mmc but nothing in computer management on my remote access machine
Is the "Virtual Disk Service" enabled on the Hyper-V server?
nostrasystemsAuthor Commented:
not if its not by default?

when i connect via computer management it hangs or gets an error?
nostrasystemsAuthor Commented:
heres the error i get
I am not sure if it is by default, but type "net start" to view a list of services at the command line.

If it shows there you can start it with "net start <SERVICENAME>".

You can set it to autostart with "sc config <SERVICENAME> start=auto"
