[libvirt-users] How to disconnect the ISO image using virsh

[Masanari Iida]

Hello,

I can attach disc ISO image to cd-rom from virsh.
And I can replace the ISO image from disc1 to disc2 using the 2nd example.

(example)
attach-disk guest01 /root/disc1.iso hdc --driver file --type cdrom
--mode readonly
attach-disk guest01 /root/disc2.iso hdc --driver file --type cdrom
--mode readonly

My question is, how can I disconnect the image from the cdrom drive using virsh.
Because, if I try to detach-disk hdc, I got following errors.

virsh # detach-disk guest01 hdc
error: Failed to detach disk
error: this function is not supported by the connection driver:
This type of device cannot be hot unplugged

What I can do is possible from virt-manager's "Disconnect" button,
(next to source path: line)  from Hardware's TAB, Disk hdc screen.
I want to do this from virsh.

OS: RHEL5.6
libvirt-0.8.2-15.el5_6.1 is used.
