Re: [Users] VM Migration failed

I looked at the logs log and only vdsm from node2 (which appears to be the src node) seems to have full info. Please attach the following complete logs: vdsm log from dst node engine log libvirt logs from both nodes. Also, can you please answer the following? libvirt and vdsm you are using? what is selinux status on both hosts (enforcing/permissive)? do you have snapshots on the vm or does it happen on a newly created disk? when you create the disk, is it from a template or is it a new image?
