After emerging bash-4.2_p7 inside an openvz virtual container the command from host node # vzctl enter VC_ID no longer works, it simply makes the console "hang" in "no mans land", without reaching the command prompt of the container. The only way out is Ctrl+C The upgrade was from bash-4.1_p10 so the problem can of course be anyware between these ebuilds. I'm absolutely sure though that it's the update of bash causing this as I explicitly tested on a container only emerging that ebuild. Apart from that the container seem to run normally and and active services like www, mail etc. works and are accessible from outside (luckily), but it's impossible to get in to the shell and do something. Only way in is through the physical container path from the host node, but that way I cannot run anything like downgrading bash.

Could this be a regression with bash or might openvz tools need to be updated?
someone on the VZ side will need to debug. ive never used openvz before nor do i have any clue how to reproduce this.
If I'm not toally wrong a similar problem was already reported to the bash-bug mailing list.
looks like a bug in openvz after all
I'll bump vzctl ASAP.
Should be fixed in vzctl-3.0.26.2. Thank you guys!
