Description Mike Cao 2011-06-01 11:08:10 UTC

Description of problem:


Version-Release number of selected component (if applicable):
# uname -r
2.6.18-264.el5
# rpm -q kvm
kvm-83-235.el5


How reproducible:
100%

Steps to Reproduce:
1.start windows guest with /dev/sr0
eg:/usr/libexec/qemu-kvm -M rhel5.6.0 -m 2048 -smp 4,sockets=4,cores=1,threads=1 -name windows2008_qcow2 -uuid cddeab65-2ded-43db-094a-fd4f8ec2d69f -monitor stdio -localtime -no-kvm-pit-reinjection -boot c -drive file=/home/windows08.qcow2,if=ide,bus=0,unit=0,format=qcow2,cache=none -net nic,macaddr=54:52:00:4f:26:51,vlan=0,model=rtl8139 -net tap,vlan=0,downscript=no -serial pty -parallel none -usb -usbdevice tablet -spice port=8001,host=0,ic=on,disable-ticketing -qxl 1 -balloon none -drive file=/home/virtio-drivers.vfd,if=floppy,format=raw,cache=none \
-drive file=/dev/sr0,if=ide,media=cdrom,bus=1,unit=0,readonly=on,format=raw 

2.right-click the media disk in the windows and select "eject" 
  (eg: D:\ is the cdrom disk in the guest ,right-click D:\, then select "eject" ,this step is *must*)

3.change cdrom from /dev/sr0 to iso image
(qemu) change ide1-cd0 en_windows_server_2008_datacenter_enterprise_standard_sp2_x64_dvd_342336.iso

Actual results:
the ISO image could be detected in qemu-monitor ,but could *not* be detected in the guest
(qemu)info block
ide1-cd0: type=cdrom removable=1 locked=0 file=en_windows_server_2008_datacenter_enterprise_standard_sp2_x64_dvd_342336.iso ro=1 drv=raw encrypted=0

Expected results:
the ISO image could be detected in the guest.

Additional info:
Without step2 ,the ISO image could be detected in the guest.

What exactly do you mean by "could *not* be detected in the guest"?

Please try

4. Load the media.  I'm not familiar with Windows, so I don't know how exactly this is done.  In Linux, it's "eject -t".

I'd expect this to make the new image available.

Comment 3 Markus Armbruster 2011-06-29 11:54:53 UTC

One more question: what if you use file=some-other.iso in step 1.?  Same result?

after step3, the iso image can be found in qemu monitor
(qemu)info block 
ide1-cd0: type=cdrom removable=1 locked=0 file=/home/en_windows_server_2008_r2_standard_enterprise_datacenter_and_web_with_sp1_x64_dvd_617601.iso ro=1 drv=raw encrypted=0

but in the guest ,we can not find it .

windows should load media itself .seems no way for me to load it in windows guest ,I will try with Linux guest and add another comment later

> I'd expect this to make the new image available.
yes ,the image was installed yesterday .

yes ,same results

what's more ,if I change the cdrom to bare-metal eg :(qemu)change ide1-cd0 /dev/sr0 ,the media in bare matal should be found in the guest ,while can not be found if change the cdrom to XXX.iso

Mike Cao attempted to reproduce this on RHEL-6, but ran into bug 729219.
