[one-users] Checkpoint file (Ver .12)

[Ruben S. Montero]

Hi,

Yes that patch was for 1.4. The solution is essentially the same for
the 1.2 version of the driver. We have been working in the driver
subsystem and the solution is not as clean...

Simply replace each virsh ocurrence with

virsh -c qemu:///session

It should be just two lines:

177:  "ssh -n #{host} virsh #{command} ;"+

to
        "ssh -n #{host} virsh -c qemu:///session #{command} ;"+

and

130: "ssh -n #{args[2]} virsh dominfo #{args[3]};"+

to

"ssh -n #{args[2]} virsh -c qemu:///session dominfo #{args[3]};"+

I could not test this if you have problems with the ssh command try to
put a single quote ' in the ssh string, like


  "ssh -n #{host} 'virsh -c qemu:///session #{command} ;"+
" echo ExitCode: $? 1>&2'")

Do not forget to close the ' in the following line...


Cheers

Ruben
