This script can restrict both incoming and outgoing speed for OpenVZ (OpenVZ 2.6.18 and 2.6.32 supported) containters and provide IPv4 and IPv6 support.

- Parallels Virtuozzo
- Parallels Cloud Server
- OpenVZ/RHEL5 2.6.18
- OpenVZ/RHEL6 2.6.32
- venet support
- Rock stable, tested very thoroughly for many years
- Tc and HTB based
- Complete IPv4 and IPv6 traffic shaping
- Very fast hash based filtering rules (only 2 lookups for thousands of filters)
- Incoming and outgoing traffic shaping (please be very careful with INCOMING shaping feature!)
- How much IP's I could have on single server? Tested up to few thousands
- What license? GPLv2 (please be careful because we changed license at 10 Nov 2014)
- Do you have support for multiple IPs per containter? Yes!
- Do you have support for IPv6? Yes, we have it!
- Do you have veth support? Unfortunately, not because IP configuration for veth is not standard.
- How I can manage speed for different CT? You need change only one Perl function.
- Install required Perl module:
yum install -y perl-Net-CIDR-Lite
- Put fastvps_openvz_shaper.pl into PATH folder (e.g. /usr/bin)
- Put fastvps_openvz_shaper_config to /etc/ folder (it's config with some logic)
- Change Perl subroutine in fastvps_openvz_shaper_config to your speed determining logic (by default all CT shaped to 30mbps)
- Add fastvps_openvz_shaper.pl to cron for run every 10-60 minutes.
Please be careful! We can't restrict incoming speed from external Internet to customer but we can slow down speed from hardware node to customer.
