Updated version of VM-Tools and libxen available

Updated version of VM-Tools and libxen available

[Anthony Liguori]

Hi,

A new version of VM-Tools and libxen are available for those 
interested.  There's a number of new features that I thought some folks 
here would be interested in.

vm-tools:
o VMX support
o vm-top (with SMP support)
o vm-balloon
o many bugfixes

libxen:
o Use the positive portion of the return code when possible
o Ensure error code is in errno
o Linux build routine
o memext ops

VM-Tools:
http://www.cs.utexas.edu/users/aliguori/vm-tools-latest.tar.gz

libxen:
http://www.cs.utexas.edu/users/aliguori/libxen-3.0.1.tar.gz

Regards,
Anthony Liguori

Anthony,

Great to see another release.  Will the vm-top work with
the existing xend toolset?  Or in other words, can I grab
vm-top from vmtools to get this functionality without having 
to change the use of existing standard tools?

Anthony, I would like to give those code a try. Could you please give
us some brief HOWTO guidance for the first steps? Do I need to stop
the xend, and run other alternative daemon to use vm-tools?

I looked at the tarball, but found no such documentation.

thank you,
aq

Hi, 

vm-tools can co-exist with xend, you don't need to stop xend in order to use 
vm-tools. To get started with it:

1) vm-tools only works with the xeno-unstable tree.

2) untar the tarball

3) make

4) make install

The "vm" script is intended to work like "xm". For more information on how to 
use the commands, you can:

1) Use man pages (They need some updating)
  # man vm

2) Use help options for syntax
 # vm help

3) Read the documenation in the docs directory

Some basic tasks:

1) Creating a domain - vm create CONFIG
 # vm create /etc/xen/vm1

2) Listing domains - vm list
 # vm list

3) Shutting down a domain - vm shutdown DOMID
 # vm shutdown 3


The vm-tools are still being developed. There does need to be an installation 
instruction added - either as a file INSTALL or in the README. A short HOWTO 
might also help. We'll be sure to add it.

Thanks,

Dan

I should probably add that the config is a bit different than the xm config. 
Please look at the man page for vm or at the example config in the scripts 
directory of the source, it's entitled "rockhopper". 

We plan to add support for using an existing xm/xend python config. I added a 
callout but haven't got around yet to creating the python script necessary to 
parse the xm/xend config and add the variables to the env. 

Thanks,

Dan

You don't need to start xend, but you need to run xcs.

hi,

could I suggest renaming the vmtools source subdirs in the future, fx as in:

xen -> libxen
src -> vmtools

This would make integrating your code with the rest of the Xen tree a 
bit easier.

best,
Jacob

Re: Updated version of VM-Tools and libxen available

[Mark Williamson]

In Linux you can bind a file to a block device using:

losetup /dev/loop0 /path/to/file

Where loop0 is an unbound loop device (most Linux installs should have at 
least loop0, loop1 ... loop 7).

You can then specify /dev/loop0 as the device to export to the domain.

When you're done, use losetup -d /dev/loop0 to remove the binding and free 
that device.

Thank you all for the guidance on how to use vm-tools. That really
help, since its documentation still lag behind development.

I have a question: as I understand, at the moment vm-tools doesnt
support file backed device, but only real block device? That means if
I want to try out this tool suite, I must (for ex.) run xenU on real
disk partitions?

Thank you,
aq
