[RHEL6.0] KVM: can't determine target name for virsh detach-disk when repeating attach and detach
Issue
- If a disk is online attached/detached to a RHEL6.0 guest OS repeatedlyusing a same target name (e.g. vda), the target device name recognized by the guest OS is incremented (e.g. vda => vdb => vdc => ...).
- As a result, admins can't easily determine a target name to detach from the guest OS, since there is no target name mapping rule between host and guest.
- How reproducible: Always
