Hi,
It seems that the console attribute needs to be defined within the
devices element. We can try a couple of things:
1. Let see if libvirt can deal with two devices elements. Try to add:
RAW = [ type = "kvm",
data = "</devices><serial type=\"pty\"><source
path=\"/dev/pts/5\"/><target port=\"0\"/></serial><console type=\"pty\"
tty=\"/dev/pts/5\"><source path=\"/dev/pts/5\"/><target
port=\"0\"/></console></devices>" ]
That is the same you have but within a device element
2. We can modify the KVM driver so the RAW attributes are generated
within the devices section. Or at least add an option to tell
OpenNebula where to put the RAW attributes.
3. If you need this for debugging purposes, you can always connect to
the VM through VNC with the GRAPHICS attribute...
Cheers
Ruben
