I cannot figure this out for the life of me but its been an issue. it eventually resolves itself once everything has "settled" after I bring the hosted-engine VM up but it takes anywhere between 15 minutes and 1 hour to completely settle http://imgur.com/a/o4S5m The picture is the best way I can describe it. From the node the engine is running on I ping the engine VM and packet loss is great. When I ping FROM the VM out to the outside world (or any IP really) there is no packet loss I have ruled out physical connectivity issues and RSTP/STP is not enabled on the switches that the ovirtmgmt network is connected to This causes a problem because the inbound checks from the nodes fails (I guess you use ICMP?) and then it starts to enter a constant flap state where the engine keeps migrating around -- *Charles Kozler* *Vice President, IT Operations* FIX Flyer, LLC 225 Broadway | Suite 1600 | New York, NY 10007 1-888-349-3593 http://www.fixflyer.com <http://fixflyer.com> NOTICE TO RECIPIENT: THIS E-MAIL IS MEANT ONLY FOR THE INTENDED RECIPIENT(S) OF THE TRANSMISSION, AND CONTAINS CONFIDENTIAL INFORMATION WHICH IS PROPRIETARY TO FIX FLYER LLC.
