Xen users - Aug 2012 - eth0 doesn't load on dom0 with kernel 2.6.32.40-jeremy

Hi Guys,

I''m working with:

   1. xen 4.1 installed from source (I followed this tutorial <
  
http://wiki.xen.org/mediawiki/images/f/f1/Building_and_Installing_Xen_4.x_and_Linux_Kernel_3.x_on_Ubuntu_and_Debian_Linux_-_Version_1.7_-_REDUCED.pdf
   >);
   2. dom0 ubuntu server 12.04 kernel 2.6.32.40-jeremy (I followed this
   tutorial <http://remusha.wikidot.com/#toc3>)

I''m trying to run remus with disk replication (I can run without disk
replication). Coz this I am trying to use kernel 2.6.32.40-jeremy. I tried
others kernels 3.x (see:
http://xen.1045712.n5.nabble.com/How-to-install-pv-guests-with-tap2-aio-for-remus-td5710672.html)
but I saw that blktap2 kernel module is not present in the mainline kernel
3.x.

The problem is: *eth0 doesn''t load on dom0 with kernel
2.6.32.40-jeremy.*
I ran these commands:

       1-  $ lspci | grep -i ethernet
            02:00.0 Ethernet controller: Broadcom Corporation Netlink
BCM57780 Gigabit Ethernet PCIe (rev 01)

       2-  $ lsmod
               dcdbas
               serio_raw

       3-  $ dmesg | grep -i eth
              "no response"

       4-  $ dmesg | grep -i eth
              "only lo"

       5-  # ifup eth0
              Cannot find device "eth0"
              Failed to bring up eth0.

Does someone have a suggestion?
Thanks

Pasi,

I was trying to use the jeremy kernel coz I was almost installing the vm
with my guest.cfg, but I haven''t had network.

I prefer to use  the default ubuntu kernel and then I followed your tip
installing this dkms <
http://xen.1045712.n5.nabble.com/attachment/4643701/0/blktap-dkms_2.6.39%2B21%2Bg3a89f82_all.deb>,
coz I think it is newer than this <http://downloads.xen.org/XCP/debian/>.
Am I right?

But as you said this way didn''t work.
Now I had doubts how to use the bugfix patches. Can you help me, please?

thanks
