Description
Basic tests for OpenVZ Linux Containers and Checkpoint/Restore In Userspace (CRIU)
Known issues
- Problems with SELinux
- In version 4.4 we introduced new script for disable SELinux
/usr/libexec/vzctl/scripts/vz-postinstall
- In version 4.4 we introduced new script for disable SELinux
- Random system freezes
- RHBZ # 982489
- Kernel older or equal 3.10
- You shall execute
vzctl exec 101 killall udevd
- You shall execute
4.3.1 specific
- Doesn't work
vzctl exec 101 ps axf
(proc is not mounted)- OpenVZ # 2658
- criu: command not found
yum install crtools
(Patch sent to maintainers)
- Doesn't work
vzctl restore 101
(VE_VETH_DEVS failure)- OpenVZ # 2659
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 *
Setup
- Open terminal
- Switch to root user:
su -
- Install:
yum install vzctl
How to test
- Create new container:
vzctl create 101 --ostemplate centos-6-x86_64
- Start container:
vzctl start 101
- Exec ps in container:
vzctl exec 101 ps axf
- Enter to container:
vzctl enter 101
- Exec ps in container directly:
ps axf
- Exit from container:
logout
- Suspend container:
vzctl suspend 101
- Restore container:
vzctl restore 101
orvzctl resume 101
- Stop container:
vzctl stop 101
Expected Results
The following must be true to consider this a successful test run. Be brief ... but explicit.
- All steps completes without error
- Steps #3, #5 shows the same. Like this:
