When i use "virsh attach-device rhel disk.xml" when the guest is booting,then i can't find the disk in the guest after booting.But i can find it by "virsh domblklist rhel",and when i want to detach it from the guest and use "virsh detach-disk rhel vdb", i still can find the disk by "virsh domblklist rhel"
The disk.xml is like:
<disk type="file" device="disk">
<driver name='qemu' type='raw' cache='none'/>
<target dev="vdb" bus="virtio"/>
Libvirt-release is 18.104.22.168 and the qemu-kvm release is 3.1.0
So i want to know why it failed to attach-disk when booting,and why we design in this way.Maybe it's better to return failure if we can't use it like this.
