Only CloudLinux 7 and CloudLinux 6 Hybrid kernel versions 3.10.0-714.10.2.lve1.5.3 and later support Reseller Limits.
To be able to use Reseller Limits you should have the latest CloudLinux 7 kernel installed. Installation command:
yum install kernel --enablerepo=cloudlinux-updates-testing
Users with CloudLinux 6 kernel should migrate to CloudLinux 6 Hybrid.
For more details, please go to Reseller Limits documentation.
How to upgrade to the kernel with Reseller Limits support?
To upgrade, please run the command:
yum install kernel --enablerepo=cloudlinux-updates-testing
And reboot a server.
Do I need to install new kernel if I want to enable Reseller Limits, if I have already run KernelCare?
KernelCare doesn't deliver functionality needed by Reseller Limits, as it is too big of a change. Reboot is required.
Can hoster manage reseller’s end user limits?
If Reseller Limits are disabled, a hoster is able to manage limits for resellers’ end users.
If Reseller Limits are enabled, a hoster has to log in as a reseller to manage limits for resellers’ end users.

End User does not buy his resources from a reseller but from a hoster directly.
Reseller's End User buys his resources from a reseller, who buys them from a hoster.

What happens when reseller hits the limit?
Reseller is a virtual entity. He cannot hit the limit. There is reseller's end user with the same name as a reseller. This end user is limited as any other reseller's end user.
Reseller's end user can hit reseller limit when end user's limit is bigger than reseller's limit. In such case, end user will be limited by reseller limit.
Or reseller limit can be hit when all resellers’ end users in total use as much resources as reseller limit.

No, he doesn't. End user gets a notification about his own limits/faults only.

Can sum of resellers’ end users limits be bigger than reseller limit?
Sure, it can. Reseller Limits limit actual total usage of resellers’ end users, but not values of their limits. Resellers’ end users can have limit bigger than reseller limit.
Can I set end user limit to be bigger than reseller limit?
Yes, a reseller can set user limit bigger than reseller limit. But our system will automatically trim exceeded user limit.

Can Reseller Limits be enabled automatically for all new Resellers created on the server?
There is no such feature available out of the box, but all supported control panels have a possibility to setup custom hooks when a new account is created. So you can use these hooks in combination with these commands:
# lvectl set-reseller res1 --speed=N% --pmem=N --nproc=N --vmem=N --maxEntryProcs=N --iops=N --io=N
Check the corresponding hooks documentation here:
for cPanel: https://documentation.cpanel.net/display/DD/Guide+to+Standardized+Hooks
for DirectAdmin: https://help.directadmin.com/item.php?id=294
for Plesk: https://docs.plesk.com/en-US/onyx/administrator-guide/59205/
What are the default limits applied to a Reseller when I enable Reseller limits for him?
The default limits are applied to a reseller when you first press Enable Reseller Limits in UI or when you simply fire lvect set-reseller without specifying the limits. Those limits are hardcoded and cannot be changed.
# Default parameters for lvp
LVP_DEFAULT = {
'cpu': 100,
'ncpu': 1,
'io': 0,
'ep': 0,
'mem': 0,
'pmem': 0,
'nproc': 0,
'iops': 0
}
Can I create package for my resellers and apply that package as a reseller limit for different resellers?
No, you cannot, Reseller limits have no connection with packages, these limits should be applied manually, limits from Packages cannot be assigned to a reseller.
