From 1d84d914065be4e91d85771fd92e7adcb8f15361 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Add --pids-limit=-1 to podman run commands in PerfCI
 Jenkinsfile

Prevents 'failed to create new OS thread (errno=11)' errors when
virtctl ssh polls multiple VMs in parallel and hits the container
PID limit.

Assisted-by: Claude Code
