From 5804052866cb35179f3520d1b21238b49ee19018 Mon Sep 17 00:00:00 2001 Message-Id: <5804052866cb35179f3520d1b21238b49ee19018@dist-git> From: Michal Privoznik Date: Tue, 14 Jul 2015 11:20:26 +0200 Subject: [PATCH] qemuDomainSetNumaParamsLive: Check for NUMA mode more wisely https://bugzilla.redhat.com/show_bug.cgi?id=1232663 In one of my previous ptaches (bcd9a564) I've tried to fix the problem that we blindly assumed strict NUMA mode for guests. This led to several problems like us pinning a domain onto a nodeset via libnuma among with CGroups. Once the nodeset was changed by user, well, it did not result in desired effect. See the original commit for more info. But, the commit I wrote had a bug: when NUMA parameters are changed on a running domain we require domain to be strictly pinned onto a nodeset. Due to a typo a condition was mis-evaluated.
