Hello Alexandre,

Yes, I'm pretty sure about dns:

# hostname
tux

# hostname -f
tux.cub.org.ua

# host `hostname`
tux.cub.org.ua is an alias for humster.cub.org.ua.
humster.cub.org.ua has address 172.16.17.3
humster.cub.org.ua has address 172.16.29.3

# host `hostname -f`
tux.cub.org.ua is an alias for humster.cub.org.ua.
humster.cub.org.ua has address 172.16.17.3
humster.cub.org.ua has address 172.16.29.3

# host 172.16.17.3
3.17.16.172.in-addr.arpa domain name pointer tux.cub.org.ua.

# host 172.16.29.3
3.29.16.172.in-addr.arpa domain name pointer tux.cub.org.ua.


As I found, error is triggered in /usr/sbin/qm, line 53, because in line 51:
    my $s = IO::Socket::UNIX->new(Peer => $path, Timeout => 120);
returned value is undef. At the time of call $path is set to
"/var/run/qemu-server/100.vnc".

Do you need some other information?

Is there opssibility to chat somewhere, like IRC, and when everything
will be solved, then post result here?

Thanks!
