[-- Attachment #1.1: Type: text/plain, Size: 16621 bytes --]

Hi all,

I am attempting to do a pci passthrough of an Intel ET card (4x1G NIC) to a
HVM.  I have been attempting to resolve this issue on the xen-users list,
but it was advised to post this issue to this list. (Initial Message -
http://lists.xenproject.org/archives/html/xen-users/2014-02/msg00036.html)

The machine I am using as host is a Dell Poweredge server with a Xeon
E31220 with 4GB of ram.

The possible bug is the following:
root@fiat:/var/log/xen# cat qemu-dm-ubuntu-hvm-0.log
char device redirected to /dev/pts/5 (label serial0)
qemu: hardware error: xen: failed to populate ram at 40030000
....

I believe it may be similar to this thread
http://markmail.org/message/3zuiojywempoorxj#query:+page:1+mid:gul34vbe4uyog2d4+state:results


Additional info that may be helpful is below.

Please let me know if you need any additional information.

Thanks in advance for any help provided!
Regards

It appears that it cannot obtain the RAM mapping for this PCI device.


I rebooted the Host.  I ran assigned pci devices to pciback. The output
looks like:

Ah, so you are looking for the xen_pt: Fix passthrough of device with ROM. 
which is not in the Xen 4.4-rc3 but in the master. 


One thing you can do is: 


cd xen/tools/qemu-xen-dir 
git fetch upstream 
git checkout origin/master 
[you should see: " HEAD is now at 027c412... configure: Disable libtool if -fPIE does not work with it (bug #1257099)"] 


Go back to main xen directory: 
cd ../../../ 
./configure 
make 
make install 


and you should be using now an newer version of QEMU with the fix.
