Hello, everyone
I have a question about hotplug of cd-rom.
version of qemu: Apr-22-2013 bb71623811686ce3c34ce724f073f5c5dd95f51b
1) start the vm:
qemu-kvm -enable-kvm -m 1024 -smp 2 -boot c -drive
file=/home/vm/winxp.qcow2,if=none,id=drive0,format=qcow2
-device virtio-blk-pci,scsi=off,drive=drive0,id=disk0 -monitor stdio -vnc
186.100.8.136:1
-device lsi,id=scsi0,bus=pci.0
2) use "drive_add" and "device_add" commands to hotplug a cd-rom:
(qemu) drive_add 0
file=/home/vm/aaa.iso,if=none,id=my-cdrom-drive,readonly=on,format=raw
(qemu) device_add scsi-cd,bus=scsi0.0,scsi-id=2,drive=my-cdrom-drive,id=my-cdrom
3) but I can't find the new cd-rom in the WindowXP vm.
4) and then, I use "pci_add" command to hotplug another cd-rom:
(qemu) pci_add auto storage
file=/home/vm/bbb.iso,if=scsi,readonly=on,format=raw,media=cdrom
5) I not only found the second cd-rom, but also found first cd-rom in the
WindowXP vm.
When I only use "pci_add" command, I can hotplug a cd-rom successfully.
Would you please tell me how to use "drive_add" and "device_add" commands to
hotplug a cd-rom?
Best Regards,
Jeremy Liu
