KVM Guest Management With Virt-Manager On Ubuntu 8.10 - Page 2

3 Using Virt-Manager

You can now start virt-manager (Applications > System Tools > Virtual Machine Manager):

Depending on if you have followed chapter 2.2, you are asked or not asked for your password. If you have followed chapter 2.2, but virt-manager doesn't start, open a terminal and start it as follows:

sudo virt-manager

This is how virt-manager looks:

If your KVM host is on a remote system, you must connect to it - go to File > Open connection...:

Select QEMU and Remote tunnel over SSH and type in the hostname or IP address of the KVM host:

If this is the first time you're trying to connect to the remote KVM host, you must type in yes:

Next type in the root password of the KVM host.

(Please note that the root account must be enabled, and that root logins must be allowed on the remote system. If the remote system is an Ubuntu system, run

sudo passwd root

to enable the root account; to check if root logins are allowed check the directive PermitRootLogin in /etc/ssh/sshd_config - you might have to restart the SSH daemon afterwards. )

You should now see a list of virtual machines running on the KVM host:

By right-clicking on a virtual machine, you can start/pause/stop it; if you select Details,...

... you will see something like this (performance graphs of the virtual machine). By clicking on the Hardware tab,...

... you can learn more about the "hardware" used by the virtual machine (and tweak some parameters):

You can connect to the virtual machine by going to View > Graphical Console:

Type in the root password of the KVM host (this will pop up only if it is a remote host):

And voilà, here's your virtual machine (in this example, it's a server vm, but of course, you can also install a desktop as a virtual machine). Click on the console to work in the virtual machine, and press CTRL+ALT to release the mouse pointer from the console:

This may be a 9.04-only issue, but when I changed the virt-manager script to "exec sudo python...," it wouldn't launch. I had to go into Preferences --> Main Menu --> System Tools/Virtual Machine Manager --> Properties and change the command to "gksudo virt-manager." That worked for me.

This might be specific to just 9.04, but instead of editing the file, you can just add yourself to the KVM and libvirt groups in Users and Groups.

Our installation of 10.04 hangs up with 'exec sudo python...'  but works fine with 'exec gksudo....'

....and of course will not create the VM file without it!

 

Many thanks for a super HowTo - Ben

Hi there! I know this is kind of off topic but I was wondering if you knew where I could locate a captcha plugin for my comment form? I'm using the same blog platform as yours and I'm having difficulty finding one? Thanks a lot! ekedbagfgdfa
