Any advice or input would be greatly appreciated! > Few questions: Are you able ping/communicate from host to engine and vice-versa? In the node, do you have the ovirtmgmt interface up? what's the output of systemctl status vdsmd -l ? Did you change the firewall settings? Which version are you running? Did you upgrade? In the hypervisor, the log /var/log/vdsm/vdsm.log might help us too. Finally, check in the hypervisor if your vms are really down, ps aux | grep qemu-kvm should return your vms process -- Cheers Douglas
