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 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!
