From d2d069fa9910d1c7a94c898355a63fca03ec5ad8 Mon Sep 17 00:00:00 2001 From: Juro Bystricky Date: Tue, 12 Sep 2017 12:23:27 -0700 Subject: qemurunner.py: wait for PID to appear in procfs We need QEMU PID in order to access "/proc//cmdline" Having a valid QEMU PID does not mean we can access the proc entry immediately, we need to wait for the /proc/ to appear before we can access it.
