Subject RE: Exposing PCIe capabilities to the Cloud Scheduler
Date Thu, 13 Feb 2014 12:07:47 GMT
Dear Edison Su and Malini Bhandaru,

I am the mentor of Pawit, who has submitted PCI passthrough patch last year.
We have been developing this feature for operating our private cloud based
on
CloudStack 4.2.1.
Now our users can deploy and migrate a VM instance with an InfiniBand
interface.

We hope to improve our patch and merge into CloudStack.
Your comments and suggestions are welcome.

Best regards,
Ryousei

> Last year, community has contributed code regarding to add PCI
passthrough into CloudStack, see the patch:
https://reviews.apache.org/r/12098/, but unfortunately, this patch doesn't
get checked in, due to lack of support from committer:
http://markmail.org/message/ux2ojhxfqwdvz2uc.
> If you guys want to pick it up, either work from scratch, or based on the
original patch, that will be great.
