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

[Rajesh Kumar Mallah]

Dear Alex ,

What do you have in the Host ? Does the guests behave as we are expecting
them to behave in our setup ?

<offtopic>
can i get rhel6.2 for trying?

| 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?
| | | in addition, if your guest has a desktop, please login and check
| if
| | 
| | | the network configuration exists issues.
| | | 
| | | Thanks,

| | 
| | 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'?    
| |

| | Alex
