Description

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

Known issues

  • criu: command not found
    • On not x8_64 arches CRIU not working. Work in progress.
  • Problems with SELinux
    • Temporary fix: setenforce 0
    • In version 4.4 we introduced new script for disable SELinux /usr/libexec/vzctl/scripts/vz-postinstall
  • Random system freezes
  • Kernel older or equal 3.10
    • You shall execute vzctl exec 101 killall udevd

4.3.1 specific

  • criu: command not found
    • yum install crtools (Patch sent to maintainers)
  • Doesn't work vzctl exec 101 ps axf (proc is not mounted)
  • Doesn't work vzctl restore 101 (VE_VETH_DEVS failure)

Bug Reports

  • If something went wrong you can see dump.log in /var/lib/vz/dump/Dump.101.fail/ and send bugreport.
  • For bugreport you shall create archive dump and attach to BZ. Create archive (as root):

cd /var/lib/vz/dump/Dump.101.fail/ && tar -cJf /Dump.101.fail.tar.xz *

  • For problems with ethernet you shall send to us ip addr; ip route from host and guest in two files.
  • New bug

Setup

  1. Open terminal
  2. Switch to root user: su -
  3. Install: yum install vzctl

How to test

  1. Create new container: vzctl create 101 --ostemplate centos-6-x86_64
  2. Start container: vzctl start 101
  3. Exec ps in container: vzctl exec 101 ps axf
  4. Enter to container: vzctl enter 101
  5. Exec ps in container directly: ps axf
  6. Exit from container: logout
  7. Suspend container: vzctl suspend 101
  8. Restore container: vzctl restore 101 or vzctl resume 101
  9. Stop container: vzctl stop 101

Expected Results

  • All steps completes without error
  • Steps #3, #5 shows the same. Like this:
Directory /proc/vz not found, assuming non-OpenVZ kernel
  PID TTY      STAT   TIME COMMAND
  551 pts/0    R+     0:00 ps axf
