Hi,
By adding following lines in a Guest .xml conf file , I'm able to send / receive
datas between host and this guest.
<channel type='pty'>
<target type='virtio'
name='arbitrary.virtio.serial.port.name'/>
<address type='virtio-serial' controller='0' bus='0'
port='1'/>
</channel>
My question is the following :
How may I find to which /dev/pts/x is mapped the source path ( from the host point of
view) ?
You have to queryy the XML from libvirt after the guest has started,
at which point libvirt will have filled in the dynamically alllocated
pty path.
Honestly, you're probably better off not using type='pty', and
instead use type='unix', which lets you specify an explicit
UNIX domain socket path upfront, avoiding the whole problem.
