[Openstack] [libvirt][nova] What can be used as equivalent to libvirt network hooks file?


Hi Fabian,

I'm working on a specific issue where an interface is configured up for sriov physical function passthrough.
The instance boot command can then specify to use that interface as either pci-sriov or pci-passthrough.

Now the following is a known issue:  If the PF is used, the VF number stored in the sriov_numvfs file is lost.
If the PF is attached again to the operating system, the number of VFs assigned to this interface will be zero.
And the recommended fix for this is to create an /sbin/ifup-local file that will set sriov_numvfs
back to its original value.

The problem I have now is that our setup/framework prevents the /sbin/ifup-local from being called.
So I'm trying to figure out a way to execute a script once the PF gets re-attached the operating system,
to put sriov_numvfs back to its original value.

I will now look into your suggestions below.

Thanks again,

François

Hi,

what are you trying to execute? Maybe there is a easier way to reach your goal?

f. e. a udev-trigger or something like listening for events in your message-queue.

Hi Fabian,

Yes, I have looked at hooks/qemu, and the xml data it receives doesn't have
the information needed to be able to logically derive the network and interface.

Thanks,

François

Hi all,

libvirt network hooks file ( /etc/libvirt/hooks/network ) does not get called when using neutron.
Any suggestion as to what could be used instead?

I need to perform some specific actions on an interface once an instance releases it.

Thanks,

François
