Subject: [Qemu-devel] Problems changing dvdrom iso during execution

I cannot change DVD roms during execution using the monitor. I can only mount a cdrom/dvdrom if I specify the iso file in the command line
x86_64-softmmu/qemu-system-x86_64 -hda ../../OSImages/sles11.qcow2 -cdrom ../../ISOz/mydvd.iso -m 2048
In the guest I can mount the iso image as you could normally expect
mount /dev/cdrom /mnt
mount: block device /dev/sr0 is write-protected, mounting read-only
Info block in the monitor yields
(qemu) info block
ide0-hd0: type=hd removable=0 file../../OSImages/sles11.qcow2 ro=0 drv=dcow2 encrypted=0
ide1-cd0: type=cdrom removable=1 locked=1 file=../../ISOz/mydvd.iso ro=0 drv=raw encrypted=0
floppy0: type=floppy removable=1 locked=0 [not inserted]
sd0: type=floppy removable=1 locked=0 [not inserted]
When I try to do a eject ide0-cd0, I get a device busy message so I have to do a eject -f ide0-cd0
After which, an info block yields:
(qemu) info block
ide0-hd0: type=hd removable=0 file../../OSImages/sles11.qcow2 ro=0 drv=dcow2 encrypted=0
ide1-cd0: type=cdrom removable=1 locked=1 [not inserted]
floppy0: type=floppy removable=1 locked=0 [not inserted]
sd0: type=floppy removable=1 locked=0 [not inserted]
I change the iso image with (or so it seems)
(qemu) change ide1-cd0 ../../ISOz/mydvd2_rom.iso
(qemu) info block
ide0-hd0: type=hd removable=0 file../../OSImages/sles11.qcow2 ro=0 drv=dcow2 encrypted=0
ide1-cd0: type=cdrom removable=1 locked=1 file=../../ISOz/mydvd2.iso ro=0 drv=raw encrypted=0
floppy0: type=floppy removable=1 locked=0 [not inserted]
sd0: type=floppy removable=1 locked=0 [not inserted]
I go back to the guest and when I try to mount:
mount /dev/cdrom /mnt
mount: /dev/sr0 unknown device
I'm running sles11 as guest and I think it may have something to do with sles11 as it works fine with ubuntu9.
Any ideas what might be happening?
Thanks
AK
