Hi Rajesh,
I saw the following XML configuration in your case-1-virsh_attach_device_first.log.txt,
what's "#012"? it seems you copy-paste it from a web, please remove it from
XML then
attach it again.
virDomainAttachDevice:9235 : dom=0x6b20a0, (VM: name=new-installed,
uuid=6122cebb-e33c-a66a-9b71-a0047c91d7bb), xml= <hostdev mode='subsystem'
type='pci' managed='yes'>#012 <source>#012
<address domain='0x0000' bus='0x04' slot='0x10'
function='0x0'/>#012 </source>#012 <address
type='pci' domain='0x0000' bus='0x00' slot='0x03'
function='0x0'/>#012 </hostdev>#012
In addition, I tried to assign/unassign a normal NICs to/from the running guest with
managed='yes' again,
indeed, the NICs hasn't been returned to host with 'managed' mode although
virsh said "Device detached successfully",
I must to stop the guest then manually return the NICs device to host via 'virsh
nodedev-reattach pci_$domain_$bus_$slot_$function'
such as virsh nodedev-reattach pci_0000_04_10_0, here is a similar bug
"https://bugzilla.redhat.com/show_bug.cgi?id=843016".
BTW, rhel6.2 isn't necessary, it should work for other platform such as fedora,
centos, etc.

Alex

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?
</offtopic>
Also i have attached the files this time.

| 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'?
| |
