Hi,
I'm trying to connect the *same* serial device to two KVM Linux machines where
one is running KGDB and the other uses the connected serial to interact with the
target machine running under KGDB.
However, I'm unable to do so. Using a pty port, I am able to use my kgdb setup
with host/VM but unable to make it work with VM/VM since it's two different pty
created on the two machines.
Anyone on this list can help me with that kind of setup ?
You don't really want to use PTYs to connect 2 VMs together.
Instead try using one of the TCP or UDP connection methods
http://libvirt.org/formatdomain.html#elementsCharTCP
eg, configure one VM with
<serial type="tcp">
<source mode="bind" host="127.0.0.1"
service="2445"/>
<protocol type="raw"/>
</serial>
and the other with
<serial type="tcp">
<source mode="connect" host="127.0.0.1"
service="2445"/>
<protocol type="raw"/>
</serial>
Regards,
Daniel
