Dear Alex ,
Thanks for the keen observation.
I noticed that #012 in the logs has replaced the newlines in the
nic.xml file. below is the nic.xml file:
------------- start of nic.xml ---------------------
<hostdev mode='subsystem' type='pci' managed='yes'>
<source>
<address domain='0x0000' bus='0x04' slot='0x10' function='0x0'/>
</source>
<address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
</hostdev>
------------- end of nic.xml ------------------------
I will go through the bug you suggested and also (possibly) try to
repeat the experiment with recent version of Centos .

Rajesh Kumar Mallah

| 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.

| 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,
| | | | Alex
| | |
| | | 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'?
