Title:
"couldn't find IFLA_VF_INFO for VF 1 in netlink response" when trying
to start libvirt VM with Chelsio VF
Status in linux package in Ubuntu:
Confirmed
Bug description:
Hi,
I have a Chelsio T62100-LP-CR and I'm trying to create a libvirt VM
that gets a VF from the NIC.
The following XML is used :
<interface type='hostdev' managed='yes'>
<mac address='52:54:00:ce:f8:e7'/>
<source>
<address type='pci' domain='0x0000' bus='0x21' slot='0x01'
function='0x4'/>
</source>
<address type='pci' domain='0x0000' bus='0x02' slot='0x00'
function='0x0'/>
</interface>
When starting the VM, libvirt fails with the following :
ubuntu@lubbock:~$ sudo virsh start vmaxino
error: Failed to start domain vmaxino
error: internal error: couldn't find IFLA_VF_INFO for VF 1 in netlink response
This is similar to bug 1496942.
I can create the VM with the VF if I pass it as a <hostdev> like this :
<hostdev mode='subsystem' type='pci' managed='yes'>
<source>
<address domain='0x0000' bus='0x21' slot='0x01' function='0x4'/>
</source>
<address type='pci' domain='0x0000' bus='0x02' slot='0x00'
function='0x0'/>
</hostdev>
