forwarded 655385 http://bugzilla.openvz.org/show_bug.cgi?id=2142 thanks Just want to report that I have filed this upstream now. // Ola On Tue, Jan 10, 2012 at 09:01:08PM +0100, Corin Langosch wrote: Package: linux-2.6 Version: 2.6.32-38 Severity: important When doing a cat /proc/self/mountinfo inside a guest the result is Cannot allocate memory.
