Re: [Xen-users] how to list vnc port in xen 4.1

[Roberto Scudeller <beto.rvs@xxxxxxxxx>]

Thanks Diego.

But I think '(vncdisplay 0)' is default, because there are 2 domains running:
# xl list
Name                                        ID   Mem VCPUs    State    Time(s)
Domain-0                                     0  2048     8     r-----    6666.9
teste4                                       2   498     2     -b----     177.3
teste3                                       3   498     2     -b----      19.6

In both:
            (vnclisten 0.0.0.0)
            (vncdisplay 0)
            (vncunused 1)

Listed by ps:
# ps -ef|grep qemu
root      2987     1  7 08:49 ?        00:00:51 qemu-dm -d 3 -domain-name teste3 -vnc 0.0.0.0:0,password -vncunused -videoram 8 -boot c -usb -usbdevice tablet -acpi -vcpus 2 -vcpu_avail 0x3 -net none -M xenfv
root      8741     1  5 Aug24 ?        00:55:41 qemu-dm -d 2 -domain-name teste4 -vnc 0.0.0.0:0,password -vncunused -videoram 8 -boot c -usb -usbdevice tablet -acpi -vcpus 2 -vcpu_avail 0x3 -net none -M xenfv

And their vnc ports:
# lsof -nPi | grep `ps -ef| grep "domain-name teste3"| awk '{ print $2}'`
qemu-dm    2987    root   17u  IPv4  78997       TCP *:5901 (LISTEN)
# lsof -nPi | grep `ps -ef| grep "domain-name teste4"| awk '{ print $2}'`
qemu-dm    8741    root   17u  IPv4  16302       TCP *:5900 (LISTEN)

In older xen, 4.0.2, the command 'xm list --long' shows vncport:
        (vfb
            (vncunused 1)
            (vnc 1)
            (uuid 841ef3a4-214a-2722-a9b2-f3936a5f0e1c)
            (location 0.0.0.0:5902)
        )


What's the new command for vncports list by domain?

Hi Roberto,

"(vncdisplay 0)" means "The VM specified is listening on port 5900",
because 5900 is the first port for VNC. VNC display 9 will listen on
port 5909.

Also VNC clients allow you to connect to displays, in the format
"server:display", in your case "server:0".

But if you need connect with the port, you can make sure installing
nmap and run "nmap localhost" to see the available ports in Dom0.

Regards,

Diego
