Hi,
I am adding a disk to my KVM virtual server, but for some reason it refuses
to honor the <address>
I have tried the following 3:
<disk type='block' device='disk'>
<driver name='phy' type='raw'/>
<source dev='/dev/nbd2'/>
<target dev='vdb' bus='virtio'/>
<serial>my-fake-serial</serial>
<address type='drive' controller='0' bus='1'
target='3' unit='2'/>
</disk>
<disk type='block' device='disk'>
<driver name='phy' type='raw'/>
<source dev='/dev/nbd2'/>
<target dev='vdb' bus='virtio'/>
<serial>my-fake-serial</serial>
<address type='pci' bus='0x00' slot='0x08'
function='0x0'/>
</disk>
<disk type='block' device='disk'>
<driver name='phy' type='raw'/>
<source dev='/dev/nbd2'/>
<target dev='vdb' bus='virtio'/>
<serial>my-fake-serial</serial>
<address type='virtio-serial' controller='0' bus='0'
port='8'/>
</disk>
I would assume the last one is the one to use, as I am using a "virtio"
bus. However, the <address> attribute is simply ignored and the disk is
always attached as this:
pci-0000:00:05.0
Further, how do I read the "my-fake-serial" from within the virtual machine?
The serial for vdb for example is in /sys/class/block/vdb/serial
I know I haven't helped with the addresses, don't know much about that,
but try attaching your libvirt version and the log of
/var/log/libvirt/qemu/<machine_name>.log.
I'll see when I'll get to you. Maybe somebody will found out in the
meantime. If not, feel free to create a bug for this.
