This regression has been introduced by https://gerrit.ovirt.org/#/c/80695/ in 4.1.6. The reason is that the CloneVmFromSnapshotModelBehavior is an ExistingVmModelBehavior but initially has the VM set to null. Hence, the isHostedEngine() code in UnitVmModel fails on NPE if the getVmConfigurationBySnapshot returns later than the AbstractVmPopupWidget.edit() gets called. fixed on 4.2 : https://bugzilla.redhat.com/show_bug.cgi?id=1491230 (currently on QA) mark as duplicate / downport to 4.1.6 minor if needed (In reply to Yanir Quinn from comment #4) > fixed on 4.2 : https://bugzilla.redhat.com/show_bug.cgi?id=1491230 > (currently on QA) > mark as duplicate / downport to 4.1.6 minor if needed 4.1.7. Please use this one then to fix in 4.1.7 (if it's an easy backport?) yes, should be an easy backport (partial pick from https://gerrit.ovirt.org/#/c/82123/) WARN: Bug status wasn't changed from MODIFIED to ON_QA due to the following reason: [Found clone flags: ['rhevm-4.1.z', 'rhevm-4.2-ga'], ] For more info please contact: rhv-devops: Bug status wasn't changed from MODIFIED to ON_QA due to the following reason: [Found clone flags: ['rhevm-4.1.z', 'rhevm-4.2-ga'], ] For more info please contact: rhv-devops (In reply to rhev-integ from comment #7) > WARN: Bug status wasn't changed from MODIFIED to ON_QA due to the following > reason: > > [Found clone flags: ['rhevm-4.1.z', 'rhevm-4.2-ga'], ] > > For more info please contact: rhv-devops: Bug status wasn't > changed from MODIFIED to ON_QA due to the following reason: > > [Found clone flags: ['rhevm-4.1.z', 'rhevm-4.2-ga'], ] > > For more info please contact: rhv-devops Yanir, I've removed the 4.2 flag - please make sure this is in the erratum for 4.1.7. Steps: 1) Create new VM 2) Start the VM 3) Create snapshot on the VM(with memory) 4) Choose snapshot and click clone button 5) VM creation from snapshot succeeded 6) Start new VM Verified on rhevm-4.1.7.4-0.1.el7.noarch Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
