## Locations Checked

There are many locations that are checked for having evidence of being a virtual machine.  The follow is a list of them:

1. (with root access) `/usr/sbin/dmidecode`
2. `/sbin/lsmod`
3. `/proc/scsi/scsi`
4. `cat /proc/ide/hd*/model`
5. `lspci`
6. `dmesg`
7. `/sys/class/dmi/id/product_name`

## Verification Steps

  1. Start msfconsole
  2. Get a session via exploit of your choice
  3. Do: `use post/linux/gather/checkvm`
  4. Do: `set session <session>`
  5. Do: `run`
  6. You should get feedback if a virtual machine environment was detected

## Options

  **SESSION**

  Which session to use, which can be viewed with `sessions -l`

## Scenarios

  Typical run against Kali with only one user (root), using ssh_login for initial shell

```
msf > use auxiliary/scanner/ssh/ssh_login
msf auxiliary(ssh_login) > set username root
username => root
msf auxiliary(ssh_login) > set password "test"
password => example_password
msf auxiliary(ssh_login) > set rhosts 127.0.0.1
rhosts => 127.0.0.1
msf auxiliary(ssh_login) > exploit

A non-virtual machine will have the following output
```
msf > use auxiliary/scanner/ssh/ssh_login
msf auxiliary(ssh_login) > set username root
username => root
msf auxiliary(ssh_login) > set password "test"
password => example_password
