From 11318b5ef6de6b2f80186a888cd5477e0ff167bb Mon Sep 17 00:00:00 2001 From: Daniel Lange Date: Sat, 25 Feb 2023 14:12:45 +0100 Subject: Remove LXC special handling for the CPU count LXC shows the real host CPU ids but can be limited in configuration as to which cores are used. Still the sysfs files are visible and the CPUs (stay) marked online. We will need to parse /sys/devices/system/cpu/online to follow LXC's logic. Revert for now until we can come up with a better handling of the LXC hacks.
