When `kernel.pid_ns_hide_child=1` sysctl flag is used it causes the proxmox v3.2-5a885216-5 (2.6.32-29-pve #1 SMP Thu Apr 24 10:03:02 CEST 2014 x86_64 GNU/Linux) to crash into kernel panic when one starts an openvz container.

It's presumably caused somehow by openvz and they have fixed it recently: https://bugzilla.openvz.org/show_bug.cgi?id=2983 (+ see 2 duplicates)

So is there any known workaround to hide children from containers from being visible on a host machine, and if not - any schedule to reintegrate the fix into pve kernel?

There is already a new kernel in the pve-no-subscription repository including that fix.
