+savevm fails with inserted CD, "Device '%s' is writable but does not support  snapshots."
+
+Hi,
+
+yesterday unfortunately a customer reported a failed snapshot of his VM. Going through the logfile I discovered:
+
+"Device 'ide1-cd0' is writable but does not support snapshots"
+
+this is with qemu-1.2.0 and 1.0.1 at least...
+
+Why writeable?
+Even if I specify "-drive ...,readonly=on,snapshot=off" to qemu the monitor-command sees the CD-ROM-device as being writeable?!
+
+Somewhere I saw a "hint" for blockdev.c:

+after installing with this small patch applied it works, so insert CD, savevm <somename> succeeds.
+This should be fixed at all correct places, and the tags "readonly=on,snapshot=off" should do it, too. Or even just work after specifying a drive being a CD-rom should do the trick ;-)
+
+Another "bad habit" is, that the ISO/DVD-file has to be writeable to be changed?
+
+Thnx for attention and regards,
+
+Oliver.
+
+Very old bug. If anyone sees this behavior, please re-file against a supported release (5.0 at time of writing, soon to be 5.1) and please paste a full command-line and steps to reproduce.
+
+(To my knowledge, this bug is not present in modern QEMU builds, but do not know when it would have changed.)
