[one-users] [Fwd: Re: Please help me get VM running]

[Cuong Hoang Bui]

Hi Tino,

It's the IM driver and IMM driver, so it depends of transfer method 
(currently I use nfs for testing). the content of src variable is an 
shell script. Lacking of cat argument makes Opennebula execution stop 
when creating an VM (onevm create VM_template_file).

With IM driver, it can't get host infomation. When I revert my changes, 
surprisingly it succeeds. In the past, the log had the same like below. 
Note that after making dir "mkdir -p /tmp/one-im/", the cat has no 
argument. I dont know why it suceeds when I try again.

/tmp/one-im/; cat > 
/tmp/one-im//one_im-91090fd8b53b1cf7ce51f3e4215506e3; if [ "x$?" != "x0" 
]; then exit -1; fi; chmod +x 
/tmp/one-im//one_im-91090fd8b53b1cf7ce51f3e4215506e3; 
/tmp/one-im//one_im-91090fd8b53b1cf7ce51f3e4215506e3'

With VM (Xen, KVM) driver, it can't deploy VMs.  Here is the log when 
create 1 new VM. It failed. Note at cat command.
