Running Commands in Virtual Machines without Network Connectivity
-----------------------------------------------------------------

If a VM cannot access a network for some reason, you can still run commands in it from the node the VM resides on. The VM in question must have the guest tools installed in it (see :ref:`Managing Guest Tools`).

You will need the VM ID that you can obtain with ``vinfra service compute server list``. You can also use a virsh domain name that you can get using ``virsh list``.

Running Commands in Linux Virtual Machines
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

To run an arbitrary command inside a Linux VM and receive the output to your console, use the ``virsh x-exec`` command. For example:

::

   # virsh x-exec 1d45a54b-0e20-4d5e-8f11-12c8b4f300db /usr/bin/bash -c 'lsblk'
   NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
   loop0         7:0    0 945.9M  1 loop
   loop1         7:1    0     5G  1 loop
   ├─live-rw   253:0    0     5G  0 dm   /
   └─live-base 253:1    0     5G  1 dm
   loop2         7:2    0    32G  0 loop
   └─live-rw   253:0    0     5G  0 dm   /
   sda           8:0    0    64G  0 disk
   sdc           8:32   0     1G  1 disk
   sr0          11:0    1     2G  0 rom  /run/initramfs/live

To copy a file to a Linux VM, use the ``virsh x-exec`` and ``cat`` commands. For example:

::

   # virsh x-exec 1d45a54b-0e20-4d5e-8f11-12c8b4f300db \
   --shell 'cat > test.file' < /home/test.file

To get a file from a Linux VM, use the ``virsh x-exec`` and ``cat`` commands as well. For example:

::

   # virsh x-exec 1d45a54b-0e20-4d5e-8f11-12c8b4f300db \
   --shell 'cat /home/test.file' > test.file

.. _Running Commands in Windows Virtual Machines:

Running Commands in Windows Virtual Machines
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

To run an arbitrary command inside a Windows VM and receive the output to your console, use the ``virsh x-exec`` command. For example:

::

   # virsh x-exec bbf4a6ec-865f-4e2c-ac21-8639d1bfb85c --shell dir c:\\
    Volume in drive C has no label.
    Volume Serial Number is D0BE-A8D1

                  5 Dir(s)  59,329,495,040 bytes free

To copy a file to a Windows VM, use the ``virsh x-exec`` and ``prl_cat`` commands. For example:

::

   # virsh x-exec bbf4a6ec-865f-4e2c-ac21-8639d1bfb85c \
   --shell '%programfiles%\\qemu-ga\\prl_cat c:\\test\\test.file' < /home/test.file

To get a file from a Windows VM, use the ``virsh x-exec`` and ``type`` commands. For example:

::

   # virsh x-exec bbf4a6ec-865f-4e2c-ac21-8639d1bfb85c \
   --shell 'type c:\\test\\test.file' > test.file
