Hi all, We have o hosted-engine deployment with two hypervisors and iscsi for VMS and NFS4 for the VM engine + ISO + Export. Yesterday we did an update from ovirt 3.5.3 to 3.5.4 along with OS updates for the hypervisors and the VM engine. After that we are unable to clone VMs, the task does not finish. We have this in vdsmd log Thread-38::DEBUG::2015-09-21 11:50:42,374::libvirtconnection::143::root::(wrapper) Unknown libvirterror: ecode: 80 edom: 20 level: 2 message: metadata not found: Requested metadata element is not present Thread-66::DEBUG::2015-09-21 11:50:43,721::libvirtconnection::143::root::(wrapper) Unknown libvirterror: ecode: 80 edom: 20 level: 2 message: metadata not found: Requested metadata element is not present Thread-67::DEBUG::2015-09-21 11:50:44,189::libvirtconnection::143::root::(wrapper) Unknown libvirterror: ecode: 80 edom: 20 level: 2 message: metadata not found: Requested metadata element is not present vdsm-python-4.16.26-0.el7.centos.noarch vdsm-4.16.26-0.el7.centos.x86_64 vdsm-xmlrpc-4.16.26-0.el7.centos.noarch vdsm-yajsonrpc-4.16.26-0.el7.centos.noarch vdsm-jsonrpc-4.16.26-0.el7.centos.noarch vdsm-cli-4.16.26-0.el7.centos.noarch vdsm-python-zombiereaper-4.16.26-0.el7.centos.noarch libvirt-daemon-driver-qemu-1.2.8-16.el7_1.4.x86_64 libvirt-daemon-driver-nodedev-1.2.8-16.el7_1.4.x86_64 libvirt-daemon-kvm-1.2.8-16.el7_1.4.x86_64 libvirt-daemon-config-nwfilter-1.2.8-16.el7_1.4.x86_64 libvirt-daemon-1.2.8-16.el7_1.4.x86_64 libvirt-python-1.2.8-7.el7_1.1.x86_64 libvirt-daemon-driver-secret-1.2.8-16.el7_1.4.x86_64 libvirt-daemon-driver-network-1.2.8-16.el7_1.4.x86_64 libvirt-lock-sanlock-1.2.8-16.el7_1.4.x86_64 libvirt-daemon-driver-interface-1.2.8-16.el7_1.4.x86_64 libvirt-daemon-driver-nwfilter-1.2.8-16.el7_1.4.x86_64 libvirt-daemon-driver-storage-1.2.8-16.el7_1.4.x86_64 libvirt-client-1.2.8-16.el7_1.4.x86_64 Thanks in advance
