This is a classic example of what happens when you run out of system resources like memory. The shell cannot create another process ( fork ) and thus you are restricted to the built-in commands provided by the shell you are using.

You copied the large file in /tmp which is tmpfs and resides on virtual memory. Dumping files in /tmp means consuming virtual memory. In turn, less room for other processes.

In this case, here is what you could do:
Code:
cd /tmp; echo *; >large_file

All of the commands are shell built-in (work in bourne and korn shells) and shell does not need to fork another process. So, cd lets you in the /tmp directory, echo lets you see the files in that and figure out the name of the file, > brings the size of the file down to zero solving your problem.

virt-copy-in(1) 					      Virtualization Support						   virt-copy-in(1)

NAME
virt-copy-in - Copy files and directories into a virtual machine disk image. SYNOPSIS
virt-copy-in -a disk.img file|dir [file|dir ...] /destination virt-copy-in -d domain file|dir [file|dir ...] /destination WARNING
Using "virt-copy-in" on live virtual machines can be dangerous, potentially causing disk corruption. The virtual machine must be shut down before you use this command. DESCRIPTION
"virt-copy-in" copies files and directories from the local disk into a virtual machine disk image or named libvirt domain. You can give one of more filenames and directories on the command line. Directories are copied in recursively. The final parameter must be the destination directory in the disk image which must be an absolute path starting with a "/" character. EXAMPLES
Update "/etc/resolv.conf" in a guest: virt-copy-in -d MyGuest resolv.conf /etc Upload a home directory to a guest: virt-copy-in -d MyGuest skel /home JUST A SHELL SCRIPT WRAPPER AROUND GUESTFISH
This command is just a simple shell script wrapper around the guestfish(1) "copy-in" command. For anything more complex than a trivial copy, you are probably better off using guestfish directly. OPTIONS
Since the shell script just passes options straight to guestfish, read guestfish(1) to see the full list of options. SEE ALSO
