Re: [Xen-devel] VMX device models not getting created anymore?

That seems to be the problem. If I add some logging, I see:
[2005-06-17 12:06:07 xend] INFO (channel:32) created event channel:
<EventChannel dom1:0:19 dom2:5:2>
[2005-06-17 12:06:07 xend] INFO (channel:32) created event channel:
<EventChannel dom1:0:20 dom2:5:3>
[..]
Things get more interesting, because self.device_channel['port1'] for
the second channel returns 19 instead of 20.
This statement is not true. I got confused because the only the first
event channel shows up in xm list --long.
The real issue is the hard coding in:
xen/include/public/io/ioreq.h:
#define IOPACKET_PORT 2
This was true before your changes went in. After your changes, xen
started sending IOPACKET events on:
<EventChannel dom1:0:19 dom2:5:2>
but the user space device models were listening on:
<EventChannel dom1:0:20 dom2:5:3>
However, if I subtract -1, everything magically works :)
I think the quick fix is to redefine IOPACKET_PORT to be 3. Will send a
patch to remove the hard coding ASAP.
