[Devel] vmalloc size (trobles with nvidia-glx)

[Kirill Korotaev]

Can you please cat /proc/meminfo after loading OVZ kernel w/o NVIDIA driver?
It's strange and OVZ shouldn't allocate so much memory...
My only guess is that you have a lot of iptables rules which are allocated in vmalloc.

If not, plz create bug in bugzilla.
