Hi,
I'm working on bug 1466451, which is about the invalid configuration of
property pci_passthrough_whitelist in nova.
My proposal for fixing this issue is:
Before start nova-compute sevice, do a precheck against /etc/nova/nova.conf
file, if the value format of pci_passthrough_whitelist doesn't match with
any of following ones, the configuration will be recongnized as invalid:
1. Only devname:
pci_passthrough_whitelist = {devname:eth0,
physical_network:physnet1}
2. Only address:
pci_passthrough_whitelist = {address:*:0a:00.*,
physical_network:physnet1}
3. Only vendor_id + product_id:
pci_passthrough_whitelist = {vendor_id:1137,product_id:0071,
physical_network:physnet1}
4. devname and address:
pci_passthrough_whitelist = {devname:eth0, address:*:0a:00.*,
physical_network:physnet1}
5. devname and vendor_id+product_id':
pci_passthrough_whitelist = {devname:eth0,
vendor_id:1137,product_id:0071, physical_network:physnet1}
6. address and vendor_id+product_id':
pci_passthrough_whitelist = {address:*:0a:00.*,
vendor_id:1137,product_id:0071, physical_network:physnet1}
7. All of them:
pci_passthrough_whitelist = {devname:eth0, address:*:0a:00.*,
vendor_id:1137, product_id:0071, physical_network:physnet1}
Now I need some suggestion to proceed:
1. Do I need to register a blueprint for fixing this issue?
2. What kind of action is appropriate when the invalid configuration of
pci_passthrough_whitelist is dectected, logging the error or raising the
error?
Thanks in advance!
