Dear De Lara Guarch, Pablo.



I checked what you mentioned.



* Fedora Linux kernel version is as follows.



     $ uname -r (print kernel name)

     3.17.7-200.fc20.x86_64



     $ uname -a

     Linux sdnlab-k01 3.17.7-200.fc20.x86_64 #1 SMP Wed Dec 17 03:35:33 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux



     $ cat /proc/version

     Linux version 3.17.7-200.fc20.x86_64 (mockbuild@bkernel01.phx2.fedoraproject.org<mailto:mockbuild@bkernel01.phx2.fedoraproject.org>) (gcc version 4.8.3 20140911 (Red Hat 4.8.3-7) (GCC) ) #1 SMP Wed Dec 17 03:35:33 UTC 2014



     $ rpm -q kernel

     kernel-3.11.10-301.fc20.x86_64

     kernel-3.17.7-200.fc20.x86_64

     kernel-3.15.6-200.fc20.x86_64



     $ cat /etc/redhat-release

     Fedora release 20 (Heisenbug)





* Vt-d seems to be enabled. I heard that the result values of 3 or 5 mean the virtualization activated.



     $ sudo rdmsr 0x3A

     5



If VT-d is enabled, and you are running on the host, you need to use “intel_iommu=on iommu=pt” in the kernel parameters.

Anyway, there is a known issue with kernels between 3.15 and 3.17, with VT-d: take a look at the bug 6.25 here:

http://dpdk.readthedocs.org/en/v2.1.0/rel_notes/known_issues.html



I suggest you  to disable VT-d and see if you problem goes away, and if so,



update your kernel and include the line above if you need VT-d enabled for any reason.



And I have strange error during the yum update.





$ sudo yum update

 You could try using --skip-broken to work around the problem

 You could try running: rpm -Va --nofiles --nodigest





* There are virtual bridge and virtual nic in the Fedora server.



$ ifconfig  or $ ifconfig -a

What is your kernel version? And also, can you check if you have VT-d enabled?

Thanks,
Pablo
