Dear Rajesh,Dear List , We are using intel 82599EB based SRIOV capable 10GbE cards on the host machine.The VFs are being assigned to the guest in pass through mode and are providing the network connectivity as expected. However when we shutdown the guest the connectivity does not comes back via the VFs on the guest in next boot unless the VFs are detached from the *guest* *before* initiating a shutdown of the guests.
(
the detach is explicitly done via virsh command
/usr/local/libvirt/bin/virsh detach-device guest01 ~/nic.xml
nic.xml contained
<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>
)
The question is anyone else facing similar problem and
if so what solution was used?
Secondly , is there anyway to automate the detaching of the
VFs from the guest when the guest is put in the shutdown
sequence ? (or for that matter destroyed).
managed is "yes"
for a PCI device, it is automatically detached from the host before
being passed on to the guest, and automatically reattached
to the host after the guest exits such as shutdown a guest.Regards, Rajesh Kumar Mallah Tel. 91-11-46710500 (Ext:303) Cell +919811255597 Website: http://www.tradeindia.com/ \|/ \|/ \|/ stop printing \|/ \|/ \|/ | | | start planting | | | _______________________________________________ libvirt-users mailing list libvirt-users@redhat.com https://www.redhat.com/mailman/listinfo/libvirt-users
