I meant raw disk devices rather than files e.g.
<disk type='block' device='disk'>
<driver name='qemu' type='raw' cache='none'/>
<source dev='/dev/server02_vg1_2tb/lv_vm03_swap'/>
<target dev='vdb' bus='virtio'/>
</disk>
I made this change by editing the xml, restarting libvirtd, then using
virsh to define the xml file and received this message:
virsh # define /etc/libvirt/qemu/bwimail02.xml
error: Failed to define domain from /etc/libvirt/qemu/bwimail02.xml
error: missing source information for device vda
Have I done something wrong, or am I missing something?
Thanks for the other notes. I'm still trying to digest it all, but
continuing to make progress.
Thanks,
Alex
