Cannon boot from DVD ISO

[mastermindpro]

I've searched this forum and elsewhere for a reason for this, but I can't find one. I'm trying to boot a KVM guest off of a Windows Server 2008 DVD ISO. I made the ISO from one of my discs. It has the Standard, Enterprise, and Datacenter options for installation.

When I try to boot the guest off the ISO, I get:

Booting from CD-Rom...
CDROM boot failure code : 0003
Boot failed: could not read the boot disk

Can the KVM build in Proxmox simply not boot from DVD ISO's? My nodes are all running PVE 1.4.

ISO booting works - I assume your ISO is faulty - how did you create them? from a retail cd? this does not work as far as I know (copy protection). Download the iso from microsoft.

I was wondering if that might be the case. I created the image using ISORecorder from the Volume License DVD that we have. I guess I was expecting an error message from ISORecorder if it couldn't create a true ISO from the disc.

boot the ISO on another system and you will see if it is an ISO issue or not. I am more or less pretty sure that this method you described does not work (and showing also no error message). If you need a windows ISO, download it form Microsoft.

and/or boot from a linux ISO to test, e.g. Ubuntu.

proxmox ve can boot KVM guests from ISO, this is what thousands of user are doing day by day ...

Tom,

After troubleshooting this a fair amount, I have to say it's not an ISO issue. I can boot a VMWare VM off of the ISO just fine everytime. I tried re-ripping it using a different utility, which generated a slightly larger ISO file, but it too wouldn't be recognized as a boot device.

I then trotted down to the datacenter and stuck the DVD into the DVD drive on the host server and mapped the virtual optical drive to the physical drive. It still wouldn't boot. It generates the same error message.

I'm lost now. Should I upgrade the node to PVE 1.5?

Before upgrading, I would first try to boot any other ISO image (Ubuntu, Debian - whatever) to see if that works. This way you can get confirmation that ISO is or is not working at all at your installation.

Cheers,
Aleks

I can boot other ISO's, like Acronis restore CD's and Windows Server 2003. I just can't seem to boot the DVD ISO for Windows Server 2008. It's present and it functions, as I can map it to a VM and open it up to do an upgrade install, I just can't boot off of it. It is somewhat strange as when I select it as the ISO, the web interface for PVE shows no optical drive attached to the VM. When I choose any one of the other ISO's, the fact that the ISO is mounted to the VM is displayed correctly in the web interface.

I was planning to upgrade last night anyway, so I already did that on all my nodes. It didn't change this behavior, though.

whats the name of the iso file?

 

[mastermindpro]

Windows Server 2008 Enterprise x64 SPLA.ISO

Are you suggesting the presence of spaces in the file name are enough to make this not work? That'd be funny.

 

[mastermindpro]

I replaced the spaces with underscores in the file name, and lo and behold...it works!

The ISO displays as mounted in the web interface and the VM boots off of it just fine. It might be cool if there was some error message that is displayed if spaces are part of the ISO file name. That's not necessary, but it might save some other moron the trouble I went through.
