QA:Testcase vzctl network

Description

Network tests for OpenVZ Linux Containers and Checkpoint/Restore In Userspace (CRIU)

Known issues, bug reports, etc
This testcase doesn't contain this information. Pass this test only after base testcase. It's contain all needed info. QA:Testcase_vzctl_base

Setup

1. Open terminal
2. Switch to root user: su -
3. Prepare sysctl settings for network:
   1. sysctl -w net.ipv4.ip_forward=1
   2. sysctl -w net.ipv4.conf.em1.forwarding=1
   3. sysctl -w net.ipv4.conf.em1.proxy_arp=1

How to test

1. Start container: vzctl start 101
2. Add network interface in container: vzctl set 101 --netif_add em1
3. Enable forwarding in virtual eth: sysctl -w net.ipv4.conf.veth101.1.forwarding=1
4. Enable proxy_arp in virtual eth: sysctl -w net.ipv4.conf.veth101.1.proxy_arp=1
5. Enter to container: vzctl enter 101
6. Enable network intarface: ip link set em1 up
7. Assign ip address to interface: ip addr add 192.168.50.240/24 dev em1
8. Add route for interface: ip route add default via 192.168.50.254 dev em1
9. Exit from container: logout
10. Enable virtual net interface: ip link set veth101.1 up
11. Add route for virtual net interface: ip route add 192.168.50.240/32 dev veth101.1
12. Enter to container: vzctl enter 101
13. Test network: ping -c 3 192.168.50.254
14. Exit from container: logout
15. Stop container: vzctl stop 101

Expected Results

• All steps completes without error
• #13 step shows like this:

PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
64 bytes from 8.8.8.8: icmp_seq=1 ttl=52 time=23.1 ms
64 bytes from 8.8.8.8: icmp_seq=2 ttl=52 time=23.6 ms
64 bytes from 8.8.8.8: icmp_seq=3 ttl=52 time=23.8 ms

--- 8.8.8.8 ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 2002ms
rtt min/avg/max/mdev = 23.104/23.544/23.856/0.343 ms

Optional

In network tests I've used two IPs, em1 network interface. More details about them:

• 192.168.50.240 - free IP from my subnet
• 192.168.50.254 - default gw for my subnet
• em1 - my work ethernet interface
