[libvirt-users] Adding a second lv as vm drive: how to set the pci part

[Mauricio Tavares]

      Let's say I have a vm, vm1, which has a lv as its hard drive:

    <disk type='file' device='disk'>
      <driver name='qemu' type='raw' cache='none' io='native'/>
      <source file='/dev/mapper/kvmtest_vm1_rootvg'/>
      <target dev='vda' bus='virtio'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x04'
function='0x0'/>
    </disk>

I could add pickles as a second drive as follows:

    <disk type='file' device='disk'>
      <driver name='qemu' type='raw' cache='none' io='native'/>
      <source file='/dev/mapper/kvmtest_pickles'/>
      <target dev='vdb' bus='virtio'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x06'
function='0x0'/>
    </disk>

but I am trying to understand the pci address entry. Must drive be on
a different slot?
