XenServer - Sudden bug - Localhost does not ping, what should I do?

Question

linux

Good afternoon!
There was a very incomprehensible situation with XenServer.
For some reason, the Internet suddenly stopped working, that is, even localhost does not respond.
Iptables Net.
Here are screenshots with the necessary information, if you need more information, ask!
Looking forward to your reply, thanks in advance!

Answer 1

What did you do before all of a sudden?

Answer 2

Try turning off selinux. For some reason, your state eth0 is unknown. Try ip link set dev eth0 down && ip link set dev eth0 up.
If it doesn't help, then just read the syslog and dmesg.
