xen discuss - Jun 2009 - diffrences between xvm-3.3/matrix-unstable and xvm-3.4/onnv-3.4

I have setup both in different BEs on my server.
Using the xvm-3.4 BE I could access my fc san devices (used for guests).
Using the xvm-3.3 BE the /devices/scsi_vhci/ is empty so san isn''t 
accessible could it be related to the msi problems???

Thx,
Florian

Ok, I checked, yes it is this problem.
Adding:
set xpv_psm:xen_support_msi = -1
to /etc/system and reboot gives me back my san luns.
Commenting this line and reboot takes them away again...

Definitely this has to be fixed before the putback is done ;)

Btw: Does b118 still stands for the putback?

Thx,
Florian

No, we missed the window.. We ran into 4 bugs in final
PIT testing.

   A domU console hang which has since been fixed
   A dom0 console panic (due to BIOS bug) which has since been fixed
   MSI problems :-)
   A Xen shadow page table bug when running a Solaris HVM guest
      with more than 2 CPUs and hap disabled.

We''re talking about disabling MSIs for the putback and
fixing it with a follow up putback.  No final decision
has been made for this.

We are looking into the Xen shadow page table bug currently.
