Hi,
Actually, the serial is not there :)
Works for me, but that's a new qemu, new libvirt and new fedora guest, see below.
Btw, as you can see in the XML, libvirt and/or KVM is completely ignoring my target="vdb" and attaches the drive to "/dev/vdi" inside the virtual server.
Yes, this is an issue, but we do state in the documentation that the target attribute is just a hint as to where to plug the disk and we currently cannot guarantee the disk name precisely.
(root@h2)-(/)# virsh --version 0.7.5
This version is very old and even though the serial element is supported, ...
(root@h2)-(/)# kvm --version QEMU PC emulator version 0.12.3 (qemu-kvm-0.12.3), Copyright (c) 2003-2008 Fabrice Bellard
... it might not be for such old qemu.
The log-file only shows the command used to start the virtual server. It does not contain any of the commands I used to attache the additional disk.
And that command would help identify whether we start qemu with the serial parameter (which I doubt with such old implementation) or not.

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.
