OK, first up is a little bug with the Proxmox web GUI... When editing a CDROM to change it from using the physical CD drive to "none", the OK button gets greyed out until an ISO storage location is chosen. I think it also happens when changing from none to physical too.
This seems to only effect IDE CD drives (odd).
Next, and more important, is when I choose "physical" on my Win2K8R2 guest, the guest becomes extremely slow. Switching the CDROM to "none" fixes this instantly. Going back to "Physical" brings things to a stop again. This happens with IDE and SCSI virtual CD drives, and does not seem to be Windows related as it still happens even if Windows doesn't have the SCSI drivers installed.
Neither are big problems to me, but could catch people out if they don't know.
