Subject [jira] [Commented] (CLOUDSTACK-8678) OOM Kills Guests
Date Sat, 08 Aug 2015 08:58:46 GMT

    [ https://issues.apache.org/jira/browse/CLOUDSTACK-8678?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14662882#comment-14662882

Daan Hoogland commented on CLOUDSTACK-8678:
-------------------------------------------

If the host.reserved.mem.mb is there and ignored I would call that a half implemented feature,
also known as bug. By your description it sound like this is exactly the functionality we'd
want, as you said. The host capacity calculation would have to take this setting into account.
I see no added value of it being sent by the agent to the management server unless it can
somehow dynamically change on a per host basis. If this is the case it must be stored as well.

agreed?

> 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,
