[libvirt-users] Getting "unknown device type" when attaching NPIV (vHBA) to vm

[Vaknin, Rami]

Hi,

I'm trying to attach a host FC HBA to VM (NPIV).

Running ovirt 3.5 on CentOS 6.7, libvirt-0.10.2-46.el6_6.6.x86_64, I created vHBA using nodedev-create command - see below HBA and vHBA.
I wrote a vdsm hook which appends the vHBA xml stanza to the devices xml element but the vm start starts without the vHBA device.

Also, when trying to attach the device manually as a live device - I get:
2016-02-01 21:30:24.216+0000: 129764: debug : qemuDomainObjBeginJobInternal:847 : Starting job: modify (async=none)
2016-02-01 21:30:24.216+0000: 129764: error : virDomainDeviceDefParse:8136 : XML error: unknown device type

Could you please help?

virsh # nodedev-dumpxml scsi_host6
<device>
  <name>scsi_host6</name>
  <parent>pci_0000_08_00_0</parent>
  <capability type='scsi_host'>
    <host>6</host>
    <capability type='fc_host'>
      <wwnn>20000024ff57d848</wwnn>
      <wwpn>21000024ff57d848</wwpn>
      <fabric_wwn>20018c604f101321</fabric_wwn>
    </capability>
    <capability type='vport_ops' />
  </capability>
</device>


virsh # nodedev-dumpxml scsi_host15
<device>
  <name>scsi_host15</name>
  <parent>scsi_host6</parent>
  <capability type='scsi_host'>
    <host>15</host>
    <capability type='fc_host'>
      <wwnn>5001a4a84992572a</wwnn>
      <wwpn>5001a4a76965d7b8</wwpn>
      <fabric_wwn>20018c604f101321</fabric_wwn>
    </capability>
  </capability>
</device>


The xml I appends:

  <devices>
...
      <device>
        <name>scsi_host16</name>
        <parent>scsi_host7</parent>
        <capability type="scsi_host">
          <host>16</host>
          <capability type="fc_host">
              <wwnn>5001a4a8cd978a73</wwnn>
              <wwpn>5001a4afa86a7378</wwpn>
              <fabric_wwn>20018c604f101411</fabric_wwn>
          </capability>
      </capability>
      </device>
      <device>
        <name>scsi_host15</name>
        <parent>scsi_host6</parent>
        <capability type="scsi_host">
          <host>15</host>
            <capability type="fc_host">
              <wwnn>5001a4a84992572a</wwnn>
              <wwpn>5001a4a76965d7b8</wwpn>
              <fabric_wwn>20018c604f101321</fabric_wwn>
            </capability>
        </capability>
      </device>

  </devices>

Thanks,
Rami.
