NAME

virt-cat - Display a file in a virtual machine

SYNOPSIS

  virt-cat [--options] domname file
 
  virt-cat [--options] disk.img [disk.img ...] file
 
 

DESCRIPTION

"virt-cat" is a command line tool to display the contents of "file" where "file" exists in the named virtual machine (or disk image).

"virt-cat" can be used to quickly view a single file. To edit a file, use "virt-edit". For more complex cases you should look at the guestfish(1) tool.

EXAMPLES

Display "/etc/fstab" file from inside the libvirt VM called "mydomain":
  virt-cat mydomain /etc/fstab
 
 

List syslog messages from a VM:

  virt-cat mydomain /var/log/messages | tail
 
 

Find out what DHCP IP address a VM acquired:

  virt-cat mydomain /var/log/messages | grep 'dhclient: bound to' | tail
 
 

Find out what packages were recently installed:

  virt-cat mydomain /var/log/yum.log | tail
 
 

Find out who is logged on inside a virtual machine:

  virt-cat mydomain /var/run/utmp > /tmp/utmp
  who /tmp/utmp
 
 

or who was logged on:

  virt-cat mydomain /var/log/wtmp > /tmp/wtmp
  last -f /tmp/wtmp
 
 

OPTIONS

--help
Display brief help.
--version
Display version number and exit.
--connect URI | -c URI
If using libvirt, connect to the given URI. If omitted, then we connect to the default libvirt hypervisor.

If you specify guest block devices directly, then libvirt is not used at all.
