I have stated it in the bug at openvz.org already [1]: this is not a OpenVZ bug, but a packaging issue:
Apparently this feature requires CONFIG_BLK_CGROUP, which is not available with stock 2.6.32 (only available from 2.6.33 according to http://cateee.net/lkddb/web-lkddb/BLK_CGROUP.html). However, the OpenVZ patch contains this config, but it does not get enabled via the Debian build config. This patch should fix it. I have done a rebuild using it, and do not get an error for "vzctl set $VZ --ioprio" anymore. # svn diff debian/config/featureset-openvz/config Index: debian/config/featureset-openvz/config =================================================================== --- debian/config/featureset-openvz/config (Revision 16444) +++ debian/config/featureset-openvz/config (Arbeitskopie) @@ -33,3 +33,6 @@ # beancounter breakage # CONFIG_KSM is not set + +CONFIG_BLK_CGROUP=y +CONFIG_CFQ_GROUP_IOSCHED=y 1: http://bugzilla.openvz.org/show_bug.cgi?id=1649#c1 -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of "unsubscribe".
