Re: [Xen-devel] Xen 4.3 PCI passthrough possible bug

Works like a charm.  I do not have physical access to the computer this weekend to verify that the cards are isolated, but the HVM starts and appears to be working well.

When do you think Xen 4.4 will be released.  The article I read mentioned it will be released in 2014 (hinting towards the end of February).  I also read 'When it is ready.'

Any timeline would be great.

Thanks again for your help!

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.

It is for QEMU, but you are right - it should have been part
