[libvirt-users] automatically detaching PCI host devices from guest for SRIOV usage.

[Alex Jia]

Hi Rajesh,
I guess you forgot to attach your attachments in here.
As usual, I tried to directly assign a PF or VF of the Intel82576
to guest on RHEL6.2, my box is Dell Optiplex 755.

Dear Alex/List  ,

I am attaching a zip file that contains a set of files.
The files that start with case-1 is the case when the PCI
device is detached prior to shutdown. case-2 is otherwise.

Kindly have a look when you have time and see if there
is any hints. 

BTW can you suggest in what free platform does SRIOV and direct
PCI assignment *really* works so that we could try on that as well.

| |   Could you attach your libvirtd.log? which's version your libvirt?

| 
| Dear Alex ,
| 
| What logging level is useful for you ? 
| 
| Dear Rajesh,
| 
| Level 1 (Debug) should be enough, but I guess it probably hasn't more
| help for us,
| you had better to login the guest then check network when you were
| meeting this issue
| again, for example, to check if network configuration is valid and try
| to restart
| relevant network services to see if the guest network can work again
| or something
| like that, In addition, you shut down the guest via running 'halt' in
| the guest,
| Does it work for you if you use libvirt relevant interface such as
| 'virsh shutdown guest'
| or 'virsh destroy guest'?
