The docs say that libvirtd has to listen on the TCP port ... checked that:
# netstat -alnp | grep libv
tcp 0 0 0.0.0.0:16509 0.0.0.0:*
LISTEN 4568/libvirtd
Be sure to use some other authentication (e.g. sasl) when using tcp
(without TLS). Even better, use tls with sasl, but that's irrelevant
to the issue now.
libvirtd runs with UID root so I assume the user I use to connect
with
has to be root as well?
It's normal connection, it can't know under which user the client is
running.
I see no group-specification in libvirtd.conf, only for UNIX sockets
...
There is no way how to set permissions per group/user of the client,
see previous point.
tested with my user sgw (in groups qemu, kvm, libvirt) and root ...
same
behavior.
From my client I see the open port with nmap:
PORT STATE SERVICE
16509/tcp open unknown
so there should be no firewall topic ...
Increased logs on the libvirtd-server, so far it only says:
End of file while reading data: Input/output error
I have to play with the log settings now.
So let me revise that:
- you can reproduce it only with virt-manager not anything else
- the disconnection happens when you do what exactly?
- you tried setting the log level for both server and client
right?
I suggest the following:
set log_levev = 1 and log_outputs="1:file:/tmp/libvirtd.log" in your
libvirtd.conf, restart libvirtd, start virt-manager like this:
LIBVIRT_DEBUG=1 virt-manager --debug &>vm.log
and reproduce the problem. If this happens to you a lot (as it doesn
IIUC), feel free to use all the data to create a bug on upstream
virt-manager and we can continue from that.
Have a nice day,
