Xen users - Apr 2010 - Success Story: debian lenny 64bit, xen 4.0, pv_ops 2.6.31.13, VT-d

Hello,

I have seen quite a bit of posts regarding Xen 4.0 on debian/ubuntu. I
just wanted to report that my first Xen4 install went great. I am
running a ASUS Z8NA-D6 Dual LGA1366 Motherboard with two Xeon 5520''s,
24GB ram, software raid-1. Everything seems to be working very well
even VT-d which is surprising :) Below is some output of my first
successful boot:

xm info
http://pastebin.com/6e5EG2Tv

xm dmesg
http://pastebin.com/8vwhkkph

dom0 dmesg
http://pastebin.com/RDDVYNgK

I used the wiki page http://wiki.xensource.com/xenwiki/Xen4.0 as a
guide and everything went well.

"vtd=1" is old/obsolete parameter, it''s not used anymore.
Also "iommu=1" is the default in Xen 4.0.0, so that''s not
needed either :)

"iommu=verbose" can be used to get more debugging output, 
especially if IO virtualization doesn''t get enabled.

Was vtd=1 mentioned somewhere there?

Nope, just an old habit. I didn''t realize it had changed. So iommu=1
should be enough by itself? I was also curious where it says vt-d for
pv guests disabled? You cant have it for both hvm and pv at the same
time?

You should update the vtd howto with that motherboard, its not that
common to see non intel boards that actually work in my experience :)

Yeah. iommu=1 is the default setting, so also that can be skipped.

iommu=pv should enable it also for pv guests.
Although pv guests don''t need iommu for pci passthrough.. it just gives
extra security.

I also succeed with Ubuntu karmic server 9.10
Using 3GB RAM, I can start 8 PV domU guests, using only 20 dom0 cpu seconds.
Furthermore, the domU array can stop(shutdown) and start again without any
errors or problems without rebooting dom0. I tried this
on Centos 5.4 with Xen 3.4.2 and the restarts were unreliable.
