Hello,
I would be grateful if you help me with next thing: I've successfully subscribed on VIR_DOMAIN_EVENT_ID_TRAY_CHANGE event in my application (QEMU based). It perfectly works and returns to me an device alias (e.g. "drive-scsi0-0-1-0"). Of course I can split this string by delimiter '-'. However, I've found private virDomainDefFindDevice function within libvirt and seems that its make correct parsing. How can I use it in my code? You should not need to parse these strings at all. The alias in any event is supposed to match the <alias> against the corresponding device in the XML. You should treat them as opaque strings.
