ASF subversion and git services commented on CLOUDSTACK-8678: ------------------------------------------------------------- Commit 99d20234d472b56d1780978317c1352d189e780b in cloudstack's branch refs/heads/master from [~kmccormick] [ https://git-wip-us.apache.org/repos/asf?p=cloudstack.git;h=99d2023 ] CLOUDSTACK-8678: Reserve RAM for KVM host OS Use host.reserved.ram.mb agent property to modify total system RAM before reporting to management server. Remove dom0ram variable and its min/max calculation. Just reserve a default of 1GB, unless overridden by host.reserved.mem.mb property. > OOM Kills Guests > ---------------- > > Key: CLOUDSTACK-8678 > URL: https://issues.apache.org/jira/browse/CLOUDSTACK-8678 > Project: CloudStack > Issue Type: Bug > Security Level: Public(Anyone can view this level - this is the > default.) > Components: Hypervisor Controller, KVM > Affects Versions: 4.4.2 > Environment: Intel Xeon Quad Core CPU L5520 @ 2.27GHz > 98 GB RAM > Ubuntu 14.04 > Running Cloustack 4.4.2 > Reporter: Josh Harshman > Assignee: Daan Hoogland > Priority: Critical > > We have several KVM nodes running Cloudstack 4.4.2. Sometimes an instance > with X amount of RAM provisioned will be started on a host that has X+a small > amount of RAM free. The kernel OOM killer will eventually kill off the > instance. Has anyone else seen this behavior, is there a way to reserve RAM > for use by the host instead of by Cloudstack? Looking at the numbers in the > database and the logs, Cloudstack is trying to use 100% of the RAM on the > host. > Any thoughts would be appreciated. > Thank you, -- This message was sent by Atlassian JIRA (v6.3.4#6332)
