Hello,
I have VPS on centos 6.5.
I have big problem with Ethernet. My server worked good to last yum update. After reboot I lost my ethernet connection. I need resolve this problem.

And now:
# ls /sys/class/net
give me only "lo"

Ifconfig shows me only lo (I haven't eth0 on list) and IP 127.0.0.1.

This is my /etc/sysconfig/network-scripts/ifcfg-eth0 (not changed after update):
DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
HWADDR=00:1c:14:01:20:94
IPADDR=78.47.211.8
NETMASK=255.255.255.255
SCOPE="peer 78.47.211.1"
IPV6INIT=yes
IPV6ADDR=02a2:4f8:d12:3d44::2/64
IPV6_DEFAULTGW=02a2:4f8:d12:3d44::1
IPV6_DEFAULTDEV=eth0

/etc/udev/rules.d/70-persistent-net.rules (is deleted). When I trying to create it manually then disappears after reboot(I known MAC address).
Rescue System on dhcp my provider works good, so I known MAC.
Now I have access to server only via tightVnc viewer on webbrowser.
How to resolve my problem on server?

CentOS uses NetworkManager. If you disable nm then any interfaces that it manages will also be disabled. If you don't want nm to manage eth0 then you need to ad to ifcfg-eth0:

I can disable NM_CONTROLLED, but this not resolve my problem. I stil have problem with eth0. When I add manually 70-persistent-net.rules and ran command: ifup eth0 then I saw error:
Device eth0 does not seem to be present, delaying initialization

Any idea?

This is my ifconfig -a:

I see that I have vmxnet instead of Realtek and I do not know why. I did just yum update and reboot. How to change this in the system to work with the network?
