[Qemu-devel] qemu-kvm-1.0.1 cdrom device with iso hotplug issue

[xuanmao_001]

Hi, there:

 

I found an issue that cdrom device hotplug iso image.

1. if I startup qemu with an iso image, then iso can easily be replaced and it worked.

2. but if I startup qemu with null image, when I change iso image use qemu monitor command "change",

   it told me with following message:

   'This disc contains a "UDF" file system and requires an operating system that supports the ISO-13346"

   "UDF" file system specification' inside VM.

    But I can opened it with tools like "UltraISO"

 

qemu version: qemu-kvm-1.0.1

vm os: winxp sp3

iso image: any

 

Following is my qemu command line:

with iso image:

qemu-system-x86_64 -cpu core2duo -m 1024 -enable-kvm -localtime -nodefaults -drive file=/var/lib/libvirt/images/fwq_test_xp_acpi.img,cache=writeback,if=virtio -drive file=/var/lib/libvirt/images/linux_image/VS2008SP1CHSX1512981.iso,if=none,media=cdrom,id=ide0-1-0 -device ide-cd,bus=ide.1,unit=0,drive=ide0-1-0,id=ide0-1-0 -net none -usbdevice tablet -vnc 0.0.0.0:3 -vga cirrus -monitor stdio

 

with null iso image:

qemu-system-x86_64 -cpu core2duo -m 1024 -enable-kvm -localtime -nodefaults -drive file=/var/lib/libvirt/images/fwq_test_xp_acpi.img,cache=writeback,if=virtio -drive if=none,media=cdrom,id=ide0-1-0 -device ide-cd,bus=ide.1,unit=0,drive=ide0-1-0,id=ide0-1-0 -net none -usbdevice tablet -vnc 0.0.0.0:3 -vga cirrus -monitor stdio
