[Xen-users] Can not access VM through VNC

Hi,
    I am trying to create a Para Virtualized Virtual Machine using a 
linux distribution ISO. I need to create it using XML-RPCs. If, I use 
virt-install to create VM it gives me a VNC port on which I can access 
the machine. But, if I use XML-RPCs to create VM and then start it using 
''xm start <domain Name>'', the machine can not be
accessed on the VNC
port specified in the XML dump. I am pasting the XML dumps created by 
both the methods.

create''*

RE: [Xen-users] Can not access VM through VNC

Hello,

 

            I do not use such configuration form, but I know, than in the
classical form You must define something like

vnc=1

vncunused=0

vncdisplay=4

vnclisten=''10.0.0.1''

 

and in this case You will connect to the port 5904 on address 10.0.0.1. 

BUT: The port specified by vnclisten is ignored if You do not specify
vncunused=0 - in other cases Xen (at least version 3.1.0) will allocate the
port randomly.

After You started the domain, You can see by 

netstat -a -n

what ports are allocated - it there something from 5900 I think, this will
be then Your port and You can try to connect to it.

 

Maybe this will be similar situation here...

 

Archie

RE: [Xen-users] Can not access VM through VNC

Hey, 

Just a pointer. Check the xend-config.sxp file and search for any options about
VNC, there will be instructions on how to enable etc.

The file is in /etc/xen/

Best of luck,
Tait

Re: [Xen-users] Can not access VM through VNC

Check whether the port 5953 is listening or not by running command 
"netstat -nalp | grep vnc". If no, check whether the paravirtualized 
framebuffer for the guest created via XML-RPC is started or not. You 
should see a process listening for that guest. Something as below.

/usr/lib64/xen/bin/xen-vncfb --vncport 5900 --listen 127.0.0.1 --domid 1 
--title <guest name>

What does --vncport say from your ps output?

Umm - on what system is xen-vncfb running? On (my) fc8, pv domains are run 
with ''qemu-dm -M xenpv ...''.

On RHEL and its variants. I use KVM on my f8, so probably, i might not 
have looked into whether this has been changed in f8 or not.

Ok - I do remember this being the case on fc7.
