NAME
virt-cat - Display a file in a virtual machineSYNOPSIS
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.
