HI!,
I am using virt-manager GUI. There I can add a `Console Device` through Add Hardware. I can add a virtio pty WITHOUT restarting the VM. also I get a pty allocated to host machine say `/dev/pty/M`
My expectation is this `host:/dev/pty/M` is connected with a `guest:/dev/ttyN`. so If I open minicom or screen and write to `host:/dev/pty/M` it will be propagated to 'guest:/dev/ttyN'. Is my expectation correct ?
If it is correct how will I know what is the guest tty allocated against this host pty ?
This is what I've tried:
dumpxml returns
<console type='pty' tty='/dev/pts/1'>
<source path='/dev/pts/1'/>
<target type='serial' port='0'/>
<alias name='serial0'/>
</console>
I expected host:/dev/pts/1 is paired with guest:/dev/ttyS0. so I opened screen/cat/echo on both sides but could not exchange messages
------
Similar to console device I can add a Serial device but that requires a reboot of the guest VM. However I tried that though I prefer to do it without a guest restart.
<serial type='pty'>
<source path='/dev/pts/1'/>
<target port='0'/>
<alias name='serial0'/>
</serial>
here also I expected host:/dev/pts/1 is paired with /dev/ttyS0 but couldn't communicate.
My sole requirement is to have a tty pair in host and guest that can be used to communicate with each other. I am using qemu-kvm.
Thank You.
