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

* Vt-d seems to be enabled. I heard that the result values of 3 or 5 mean the
virtualization activated.
$ sudo rdmsr 0x3A

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

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