When a VM is migrated från one ESX host to another the VM:s virtual floppy with mounted floppy image gets disconnected. It is still listed as "Connect at Startup" but not "Connected". I cant find any solution rather than dont migrate the VM.
Is there any information about connected virtual floppy and vMotion?
I think that is by design
I found the New-VM -DRSAutomationLevel that can be set during creation of a VM. I will try to use this settings to prevent the VM to be migrated.
