Virtualization With KVM On An OpenSUSE 11.3 Server - Page 2

5 Connecting To The Guest

OpenSUSE 11.3 Desktop:

The KVM guest will now boot from the Debian Lenny 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 11.3 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 11.3 KVM host.

Go to File > Add Connection... to connect to our OpenSUSE 11.3 KVM host:

Select QEMU/KVM as Hypervisor, then select Remote tunnel over SSH from the Connection drop-down menu, ...

... type in the hostname (server1.example.com) or IP address (192.168.0.100) of the OpenSUSE 11.3 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 11.3 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 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 11.3 KVM host command line:

OpenSUSE 11.3 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).
