Steps to Reproduce: 1. # virsh define rhel5u4.xml 2. # virsh start rhel5u4 3. # virsh attach-device rhel5u4 interface.xml interface.xml info: <interface type='network'> <mac address='54:52:00:2b:d2:64'/> <source network='default'/> </interface> Actual results: error:Failed to attach device from interface.xml error:this function is not supported by the hypervisor:device type 'interface' cannot be attached. Expected results: Device attached successfully Wait, which is it? In the first comment, you mention this XML:
<disk type='file' device='disk'>
<source file='/var/lib/libvirt/images/RHEL-Server-5.4-64-2.qcow2'/>
<target dev='hdb' />
</disk>
Which, indeed, cannot be hotplugged, so there is no bug there. But then in comment #1, you talk about network attaching. Which is it? The first case is not a bug, and I'm not sure about the second case, but they need to be separated since they are two different things.

Neither IDE disks, nor network interfaces can be hotplugged. Only virtio or scsi disks. That said I have a strong feeling virtio / scsi hotplug will be broken anyway: http://www.redhat.com/archives/libvir-list/2009-July/msg00115.html The following lines is the disk1.xml which I edited.
<disk type='file' device='disk'>
<source file='/var/lib/libvirt/images/RHEL-Server-5.4-64-2.qcow2'/>
<target dev='hdb' />
</disk>
OK. As both Dan and I point out, that can't work, so this is NOTABUG. If there is another bug you run across (like the mailing list pointer above), please open that as a separate bug. And one issue per bug, please. Chris Lalancette |
