[libvirt-users] machine='pc-q35-2.1' and sata controller

[Thomas Stein]

Hello.

I'm not able to disable the sata controller on a machine='pc-q35-2.1' type VM. 
Whenever i delete:

    <controller type='sata' index='0'>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x1f' 
function='0x2'/>
    </controller>

it gets added again when i close the editor. 

The reason i would like to delete the sata controller is this error while 
trying to migrate the machine:

2015-02-23 19:04:11.181+0000: 1972: error : qemuMonitorJSONCheckError:381 : 
internal error: unable to execute QEMU command 'migrate': State blocked by 
non-migratable device '0000:00:1f.2/ich9_ahci'

Someone has an idea to solve this?

thanks and cheers
