Thanks for your response. Does it work if the guest uses ide based CD's: rmmod ide-scsi modprobe ide-cd There isn't an ide-scsi but there is a scsi_mod and when I try to remove that it gives ERROR: Module scsi_mod is in use by sr_mod,sg,sd_mod,libata
modprobe ide-cd seems to work. However it doesn't fix the problem. Interestingly, before doing modprobe ide-cd, linux> lsmod | grep ide ide_pci_generic 4652 0 ide_core 115068 2 ide_pci_generic, piix After the modprobe ide-cd, I get ide_cd_mod 33984 0 cdrom 36200 2 ide_cd_mod, sr_mod ide_pci_generic 4652 0 ide_core 115068 3 ide_cd_mod, ide_pci_generic, piix
