<blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">> To be sure, are you actually talking about the "mqueue" from <mqueue.h> ?<br>> Because this is api I want to use.<br>
> The filesystem is not mandatory but it would be useful for me to keep track<br>> of the created message queues.<br>I'm talking about Message Queues, one of forms of classical IPC,<br>aparrently I wasn't aware of new real-time message queues recently<br>
introduced. Since this is fairly recent it seems like it's not virtualized<br>yet ( AFAIK virtuozoo team does such large jobs only on requests from<br>larger paying customers, for example IPC message queues were needed for DB2<br>
using customets ), though you should be able to use it from VE's (without<br>mounting mqueue filesystem).<br>But since it's not virtualized, mqueues would be visible to all guests and<br>the host too, like this:<br>
