What were you trying to do that didn't work?
VM can start successfully with invalid rom setting
Please provide the package NVR for which bug is seen:
libvirt-9.5.0-7.el9_3.x86_64
How reproducible:
100%
Steps to reproduce
1. the interface with <rom bar="off" file="/usr/share/ipxe/1af41000.rom"/> can start successfully.
# virsh dumpxml rhel --xpath //interface <interface type="network"> <mac address="52:54:00:66:84:76"/> <source network="default"/> <model type="virtio"/> <rom bar="off" file="/usr/share/ipxe/1af41000.rom"/> <address type="pci" domain="0x0000" bus="0x01" slot="0x00" function="0x0"/> </interface> # virsh start rhel Domain 'rhel' started # virsh dumpxml rhel --xpath //interface <interface type="network"> <mac address="52:54:00:66:84:76"/> <source network="default" portid="60f0a578-42bb-4502-8e03-5be19ba82208" bridge="virbr0"/> <target dev="vnet15"/> <model type="virtio"/> <alias name="net0"/> <rom bar="off" file="/usr/share/ipxe/1af41000.rom"/> <address type="pci" domain="0x0000" bus="0x01" slot="0x00" function="0x0"/> </interface>
2. Hotplug interface with <rom bar="off" file="/usr/share/ipxe/1af41000.rom"/> will fail:
# virsh domiflist rhel Interface Type Source Model MAC ------------------------------------------ # cat interface.xml <interface type="network"> <source network="default"/> <model type="virtio"/> <rom bar="off" file="/usr/share/ipxe/1af41000.rom"/> </interface> # virsh attach-device rhel interface.xml error: Failed to attach device from interface.xml error: internal error: unable to execute QEMU command 'device_add': Hot-plugged device without ROM bar can't have an option ROM
Expected results
The validation should be the same for hotplug and start vm
Actual results
Start vm should fail with the confusing rom setting
