Hi Yunhong & Yongli, In the routine _prepare_pci_devices_for_use(), it’s referring to dev[‘hypervisor_name’]. I didn’t see code that’s setting it up, or the libvirt nodedev xml includes hypervisor_name. Is this specific to Xen? Another question is about the issue that was raised in this review: https://review.openstack.org/#/c/82206/. It’s about the use of node id or host name in the PCI device table. I’d like to know you guys’ thoughts on that. thanks, Robert -------------- next part -------------- An HTML attachment was scrubbed...
