5 Connecting To The Guest

OpenSUSE 12.1 Desktop:

The KVM guest will now boot from the Debian Squeeze Netinstall CD and start the Debian installer - that's why we need to connect to the graphical console of the guest. You can do this with virt-manager on the OpenSUSE 12.1 desktop.

Run

virt-manager

as a normal user (not root) on the desktop to start virt-manager (this is exactly the same on an Ubuntu desktop).

When you start virt-manager for the first time, you will most likely see the following message (Could not detect a default hypervisor.). You can ignore this because we don't want to connect to the local libvirt daemon, but to the one on our OpenSUSE 12.1 KVM host.

Go to File > Add Connection... to connect to our OpenSUSE 12.1 KVM host:

Select QEMU/KVM as Hypervisor, then check Connect to remote host, select SSH from the Method drop-down menu, fill in root in the Username field, type in the hostname (server1.example.com) or IP address (192.168.0.100) of the OpenSUSE 12.1 KVM host in the Hostname field, and click on Connect:

If this is the first connection to the remote KVM server, you must type in yes and click on OK:

Afterwards type in the root password of the OpenSUSE 12.1 KVM host:

You should see vm10 as running. Mark that guest and click on the Open button to open the graphical console of the guest:

Type in the root password of the KVM host again (you might have to minimize the vm10 Virtual Machine window to see the password window):

You should now be connected to the graphical console of the guest and see the Debian installer:

Now install Debian as you would normally do on a physical system. Please note that at the end of the installation, the Debian guest needs a reboot. The guest will then stop, so you need to start it again, either with virt-manager or like this on our OpenSUSE 12.1 KVM host command line:

OpenSUSE 12.1 KVM Host:

virsh --connect qemu:///system

start vm10

quit

Afterwards, you can connect to the guest again with virt-manager and configure the guest. If you install OpenSSH (package openssh-server) in the guest, you can connect to it with an SSH client (such as PuTTY).
