Description Rolf Fokkens 2015-07-19 09:25:22 UTC

Description of problem: Many online LXC documents suggest to map uid/gid's to like 100000 or 1000000 up. This is nor supported by virt-manager, because entry fields for user namespace are limited to 65536 max.


Version-Release number of selected component (if applicable):
virt-manager-1.2.1-1.fc22.noarch


How reproducible: 100%


Steps to Reproduce:
1. start virt-manager
2. create an LXC container
3. try to map UID's to any number > 65536 and note it switches back to 65536

Actual results: Limitation to 65536


Expected results: UID mapping up to 100000 or 1000000 like suggested in LXC docs
