Hi again The following is a design draft for a new feature of oVirt-engine planned for 3.1 The feature allow devices in guest virtual machines to retain the same PCI address allocations as other devices are added or removed from the guest configuration. This is particularly important for Windows guests in order to prevent warnings or reactivation when device addresses change. This feature is supported by libvirt and should be implemented by RHEVM and VDSM. When creating a VM, QEMU allocates PCI addresses to the guest devices, these addresses are being reported by libvirt to VDSM and VDSM should report it back to RHEVM. RHEVM should persist the PCI addresses and report it as part of the VM configuration on the next run. If a change to the VM devices occurred RHEVM should detect the change and persist the new PCI addresses. Please review. Thanks Eli Mesika Redhat ISRAEL ----- Original Message -----
