ASF subversion and git services commented on CLOUDSTACK-6203: ------------------------------------------------------------- Commit bbaec7bae87fde2c93568a042b8cd085b57bf0d1 in cloudstack's branch refs/heads/master from [~mlsorensen] [ https://git-wip-us.apache.org/repos/asf?p=cloudstack.git;h=bbaec7b ] CLOUDSTACK-6203: Correct documentation for KVM migration tuneables > KVM live migration improvement > ------------------------------ > > Key: CLOUDSTACK-6203 > URL: https://issues.apache.org/jira/browse/CLOUDSTACK-6203 > Project: CloudStack > Issue Type: Improvement > Security Level: Public(Anyone can view this level - this is the > default.) > Components: KVM > Reporter: Marcus Sorensen > Assignee: Marcus Sorensen > Fix For: 4.4.0 > > > Run the KVM live migration in a thread so we can monitor it. This will allow > us to see how long migrations are taking and do things like pause the vm if > migration is stalling (per user defined time limit) to quickly complete > migration, or set the domain's max downtime during cut-over between machines > (higher values make migration of busy vms easier, lower values may make > migration stall). In the future we can add the autoconvergence flag that > stalls VMs for a few ticks to allow memory copy to catch up, but it will be > awhile before libvirt that's shipped in a distro supports it, so these > tunables may be useful now. -- This message was sent by Atlassian JIRA (v6.2#6252)
