Description of problem: After moving a VM from one cluster (4.3 compatibility version) to another (4.4 compatibility version) the VM fails to boot. Version-Release number of selected component (if applicable): ovirt-engine-4.4.1.10-0.1.el8ev.noarch How reproducible: Always Steps to Reproduce: 1. Stop the VM running in a cluster with 4.3 compatibility version 2. Edit the VM and change the cluster to one with 4.4 compatibility version 3. Save the VM configuration 4. Try to start the VM Actual results: The VM fails to start with the following error: ~~~ internal error: Bus 0 must be PCI for integrated PIIX3 USB or IDE controllers (code=1) (vm:1629) ~~~ Expected results: The VM starts normally
Yet another flow where the VM is not adjusted to Q35 - this time moving VMs between clusters
This bug is in POST status for ovirt 4.4.4. We are now in blocker only phase, please either mark this as a blocker or please re-target.
Verification builds: ovirt-engine-4.4.4.7-0.1.el8ev vdsm-4.40.40-1.el8ev.x86_64 libvirt-daemon-6.6.0-7.module+el8.3.0+8424+5ea525c5.x86_64 qemu-kvm-5.1.0-14.module+el8.3.0+8438+644aff69.x86_64 Verification scenario: 1. Run VM with i440FX chipset with BIOS. 2. Verify VM is running, verify VM is running with correct devices. 3. Power off VM and change chipset to Q35 chipset with BIOS. 4. Run VM 5. Verify VM is running, verify VM is running with correct devices (Q35 devices). 6. Repeat steps 1-5 using the same VM few times more.
I'm afraid the previous test didn't reflect the change properly- it has nothing to do with the compatibility version. If the VM was set with chipset X and changes to chipset Y when its cluster changes, then the device addresses and unmanaged devices are cleared. For this to happen, the VM has to be set without custom bios type, i.e., with bios type = cluster-default, and the chipset of the cluster has to change from i440fx to q35 or vice versa. Steve, could you please update the doc?
