Re: [Xen-users] xm console does not return a console

["piyush masrani" <masrani.piyush@xxxxxxxxx>]

Where should i use this loopback address? in vncviewer? it is not working... My Dom0 has IP 10.105.41.15...(10.105.41.104 is IP of the guest domain...how is it related with eth0 IP? i didnt get that...)
i had not attached the files, i had copy-pasted the contents... Attaching the files herewith...

Use loopback address and not the eth0 IP.

Try 127.0.0.1 instead of 10.105.41.104.

I couldn't see your configuration file in the email.

I tried out both of these commands
vncviewer 10.105.41.104:5900
vncviewer 10.105.41.104:5901
Both are giving the above error...

Yes, the domain is created, xm list displays the domain in the running state. I am also able to ping it.

First of all, Are you sure that your domain is created and booted properly.

If yes, is it a HVM or a PV guest?

Check in xm list whether your domain is created and running.

What does xm create –c show?

If xm list shows your domain and still you are not able to connect to the console.

 

Use a vncviewer to attach to a console.

For example : vncviewer 12.0.0.1:5900

Use 5901 if 5900 is not working.

As you keep creating additional VM's increment the screen number 590x. I guess this helps.

Subject: [Xen-users] xm console does not return a console

 

Hi

I have installed xen 3.10 on ubuntu 7.10 (Gutsy Gibbon) through repositories...
I followed the following link:
http://www.howtoforge.com/ubuntu-7.10-server-install-xen-from-ubuntu-repositories

 I am able to create Guest VMs on it by using xen-create-image and able to run them by using xm create. But i am not getting the console of the created VMs( xm console is not working. Not even by using the option -c in xm create)...The shell in which i run these commands don't return any prompt...what should i do?

Thanking in advance
