What happens when you suspend the QEMU machine to RAM? I believe the

try the same test on bare-metal (hint: boot to emergency mode to bypass
anything that udev can do with locking the tray, then use sg_prevent to
toggle the state).
I've booted to init 1, then ejected the CD-ROM tray and run the
pm-suspend. The computer has suspended successfully. And again
immediately after the computer is turned on before the screen is turned
on the CD-ROM tray is closed.
Ok, these are good signs. :)
I don't have SCSI CD-ROM device to use the sg_prevent.
All CD-ROMs ultimately speak SCSI (via ATAPI). You don't have /dev/sr0?

Yes I have. If I run "sg_prevent /dev/sr0" the CD-ROM tray could be
still opened. Even with "sg_prevent -p 3 /dev/sr0".
