Hi, to document and clarify some facts about HA VMs to users, especially regarding I/O errors, I work on a HOWTO document to be added to oVirt Wiki. If you know how HA VMs or related mechanisms (such as VM handling on I/O errors) work and would like to help review the document, please look at the pull request: https://github.com/oVirt/ovirt-site/pull/1530 Thanks, Milan
