Re: [ovirt-users] Ovirt backups lead to unresponsive VM

The VM that failed is named Win-FileServer and is a Windows 2016 server 64bit with 300GB of disk. During the cloning step the VM went unresponsive and I had to stop/start it. I am attaching the logs.I have another VM with same OS (named DC-Server within the logs) but with smaller disk (60GB) which does not give any error when it is cloned. I see a line: EVENT_ID: VDS_BROKER_COMMAND_FAILURE(10,802), Correlation ID: null, Call Stack: null, Custom ID: null, Custom Event ID: -1, Message: VDSM v2.sitedomain command SnapshotVDS failed: Message timeout which can be caused by communication issues I suggest adding relevant vdsm.log as well. Y. I appreciate any advise why I am facing such issue with the backups. thanx, Alex On Tue, Jan 30, 2018 at 12:49 AM, Alex K <rightkicktech(a)gmail.com&gt; wrote: > Ok.
