https://github.com/oVirt/ovirt-engine/blob/master/backend/manager/modules/utils/src/main/java/org/ovirt/engine/core/utils/ovf/OvfReader.java#L449 causes the single PCI setting to be enabled when there's no SinglePciQxl item in the OVF (oVirt specific). This causes invalid configuration for all Windows guest OSes.
When missing we should initialize it with the OS type default.
Is any change needed to the OVF that virt-v2v generates?
I chatted to Michal on IRC and the answer is no.
1. From host CLI shell, use virt-v2v command to import different Windows OS types and Linux OS types to RHV using VDDK input mode (-io vddk).
2. From RHV Webadmin, edit each VM -> console and verify:
Linux VMs: OS type is equal to source VM, single PCI checkbox is not grayed out and checked.
Windows VMs: OS type is equal to source VM, Single PCI checkbox is grayed out and inaccessible
3. Run each VM and verify VMs are running properly and VM console can be opened.
