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

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

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...

#  If you choose to use loopback images, which are simple to manage but

#
#  New instances will be stored in subdirectories named after their

# 
##
# dir = /home/cse/Desktop/MTP

#
#  Installation method.
#
#  There are four distinct methods which you may to install a new copy
# of Linux to use in your Xen guest domain:
#
#   - Installation via the debootstrap command.
#   - Installation via the rpmstrap command.
#   - Installation by copying a directory containing a previous installation.
#   - Installation by untarring a previously archived image.
#
#  NOTE That if you use the "untar", or "copy" options you should ensure
# that the image you're left with matches the 'dist' setting later in
# this file.
#
#
##
#
# 
# install-method = [ debootstrap | rpmstrap | copy | tar ]
#
#
install-method = debootstrap

#
# If you're using "copy", or "tar" you will need to specify the
# source location to copy from, or the source .tar file to unpack.
#
# You may specify that with a line such as:
#
# install-source = /path/to/copy
# install-source = /some/path/img.tar
#
#

#
##
#  Command definitions.
##
#
# The "debootstrap" and "rpmstrap" commands are hardwired into the
# script, but if you wish to modify the commands which are executed
# when installing new systems by a "copy" or "tar" method you can
# do so here:
#
# install-method=copy:
# copy-cmd = /bin/cp -a $src/* $dest
#
# install-method=tar:
# tar-cmd  = /bin/tar --numeric-owner -xvf $src
#

##
#  Disk and Sizing options.

memory = 64Mb    # Memory size
swap   = 256Mb    # Swap size

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

xm console or xm create -c shows the following output and then the shell just hangs.

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

-Piyush
