We are running Bionic Beaver on the host machine and Xenial on the client running virt-manager. We do see the vendor name and device name for other devices. Note we do have an entry in pci-ids and even inside the guest OS we can see the device name upon booting the OS. E.g. Athens is our guest OS hostname

virt-manager/libvirt asks libpciaccess for this info, which from looking
at the source seems to query /usr/share/hwdata/pci.ids which is the same
method that lspci uses in my simple strace attempt. So I'm not sure why
you're seeing different output... maybe there's a bug somewhere, or
maybe lspci has an alternate name of looking up these strings
