Hello,

I successfully migrated a Windows Server 2003 VM from VMware to Proxmox using the import feature. However, when I boot the VM, it immediately displays a blue screen. If I change the disk bus type from SCSI to IDE, the VM boots successfully.

Has anyone experienced this issue before? If so, how did you resolve it?
 
in short - your 2003 server has storage drivers configured, most likely from your old hardware. to boot up on different physical hardware (i.e. motherboard change) or different virtual hardware you need to reset storage driver config to ide/ahci.

this can be done in multiple ways, manual by hand or with hard disk tools, i.e. if you create a windows2003.vmdk (VMware Virtual Hard Disk) from you machine, the software create an image, and after that a driver reset and registry modify. this virtual disk can be imported.
 
Hello Aaron, if i buy support subscription can i boot my win2003 and winxp via scsi in proxmox?
There‘s no difference in Proxmox VE‘s funcionality with our without subscriptions. Except for support you‘ll gain access to the Enterprise update repo. But all this is not a matter how to get old systems running as a VM.
 
I had to migrate some old machines and I run into this problem.
The way I was able to fix this was:

change the disk to IDE and then boot the machine;
add a small scsi disk to the machine and it would appear on the device manager;
then I would use the virtio ISO to install the missing drivers;
and finally would remove the small disk and change the IDE for SCSI.

The process is annoying and probably there is a easier way, but this is how I made it work for me
