Public bug reported:
Description:
On Ubuntu 26.04 (Daily Build 20260323), the "Add New Virtual Hardware" wizard
in virt-manager does not display proper vendor/device descriptions for PCI
devices. Only PCI addresses are shown, or the descriptions are missing/generic.
In comparison, Ubuntu 24.04 correctly displays both PCI addresses and
descriptive strings (e.g., "Intel Corporation Raptor Lake USB 3.2") on
the same hardware and with the same configuration.
Steps to reproduce:
1. Install Ubuntu26.04 (Daily Build-20260323)
2. Install desktop environment and virtualization tools:
# apt-get install ubuntu-desktop lightdm virt-manager.
3. Enable IOMMU by adding intel_iommu=on,iommu=pt to GRUB
4. Enable Virtual Functions (VFs) on a physical NIC:
# echo 2 > /sys/class/net/ens13f0np0/device/sriov_numvfs
5. Open virt-manager and create a RHEL9.7 VM (via ISO/CDROM), and shut down the
VM after installation.
6. Go to "Add New Virtual Hardware" -> "PCI Host Device".
Expected Result: The list should display both PCI addresses and device
descriptions (e.g., 0000:11:00.2 Intel Corporation Ethernet
Controller...).
Actual Result: Only PCI addresses are shown (or descriptions are
missing/generic), whereas they are correctly displayed in Ubuntu 24.04.
Additional information:
- The issue does not occur on Ubuntu 24.04 with the same hardware and setup.
