Troubleshooting instack-virt-setup Failures¶

Known Issues:¶

• Due to a bug in libvirt, it is possible for instack-virt-setup to fail with an error such as the following:

  libvirt: QEMU Driver error : unsupported configuration: This QEMU doesn't support virtio scsi controller
  Traceback (most recent call last):
  File "/usr/libexec/openstack-tripleo/configure-vm", line 133, in <module>
      main()
  File "/usr/libexec/openstack-tripleo/configure-vm", line 129, in main
      a = conn.defineXML(libvirt_template)
  File "/usr/lib64/python2.7/site-packages/libvirt.py", line 3445, in defineXML
      if ret is None:raise libvirtError('virDomainDefineXML() failed', conn=self)
  libvirt.libvirtError: unsupported configuration: This QEMU doesn't support virtio scsi controller
  

  The workaround is to do delete the libvirt capabilities cache and restart the service:

  rm -Rf  /var/cache/libvirt/qemu/capabilities/
  systemctl restart libvirtd
