Hello. Is that possible to create virtio-serial port that on host listens
tcp socket and how to avoid duplicate listened ports in case of migration?

Hello,
not, right now it is not possible. Why don`t you want to just assign
unique paths for socket name, derived, say, from VM` UUID?

In case of unix domain sockets paths not problem, but i want to connect to
each qemu-ga address from central point. I don't want to use socat , as i
see qemu have ability to specify host and port and in this case qemu
listens tcp port on this address. But in libvirt schema i can't provide
host and port.

From http://libvirt.org/formatdomain.html#elementsCharTCP
<devices>
<serial type="tcp">
<source mode="connect" host="0.0.0.0"
service="2445"/>
<protocol type="raw"/>
<target port="1"/>
</serial>
</devices>
(side note, I wonder why the heck we try to connect to 0.0.0.0:2445 in
the example)
I'd say substitute 0.0.0.0 with the IP address of your mgmt host. And
use unique port number per domain, otherwise you'd have to pass XML with
changed/unique port upon migration.

Michal, I suspect that Vasily mentioned channel block where
virtio-serial setup belongs, not serial. For now, libvirt does not
allow to add TCP connection inside.

This is character device, but i need channel with virtio serial. But
serial also may be useful.... Thanks
