Compatilbility:
- Parallels Virtuozzo

FAQ
- 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.
Installing
- 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.
