[openstack-dev] [nova][pci] A couple of questions

0 votes

Hi Yunhong & Yongli,

In the routine preparepcidevicesforuse(), it?s referring to dev[?hypervisorname?]. I didn?t see code that?s setting it up, or the libvirt nodedev xml includes hypervisor_name. Is this specific to Xen?

Another question is about the issue that was raised in this review: https://review.openstack.org/#/c/82206/. It?s about the use of node id or host name in the PCI device table. I?d like to know you guys? thoughts on that.

thanks,
Robert

Hi, Robert
For your first question, I suspect it's something wrong and should be 'devi_id', which is the hypervisor's identification for the device. I will leave Yongli to have more comments on it.
For the second one, thanks for point the issue out. Yes, I'm working on fixing it.

Hi Yunhong,

Thanks for the prompt response. For the second one, are you working on the existing bug, or a new one? If it?s a new bug, please let me know the bug number.

Hi, Robert

     For your first question, I suspect it's something wrong and 

should be 'devi_id', which is the hypervisor's identification for the
device. I will leave Yongli to have more comments on it.

sorry for later, this name is libvirt returned device name, use to
oprate the device via libvirt later. device_id might a good name for this.

Yongli He

     For the second one, thanks for point the issue out. Yes, I'm 

working on fixing it.
