virt-install cannot mount virtio iso during installation

Hi guys.

I have seen, read and test to install a windows 7 vm under centos 6 and kvm.

I have install windows under kvm a lot of times, but is my first time
with virtio.

I want to try virtio drives, I have install virtio from fedora repo,
download the iso, etc.

I have try different options trying to understand how kvm want the
option to add my virtio iso drive as cdrom.

virt-install --name virtio --description='Windows 7 Virtio x64'
--memory 4096 --vcpus 2 --arch=x86_64 --cdrom
/var/isos/win7_prox64.iso --os-variant win7 --disk
/dev/vg_vms1/virtio,bus=virtio --disk

ssmtp not working properly.


I have a sever running centos 7, I had install ssmtp from epel repo,
but every time I test in my console I got this ugly message.

I receive a email from a user telling me that they have issues sending
emails to some company.

I have centos 5.11 x64 postfix 2:2.3.3-7.el5.

Now, I filter the domain and found this logs:
