Web based KVM management for Ubuntu
Cloud.com Cloudstack runs on Ubuntu 10.04. Obviously Eucalyptus too. I know you don't want cloud features, but you can just ignore them if you want. Perfectly viable as plain hypervisor management, so long as you have an external management box.
As you've noticed, other tools like Karesansui and oVirt are packaged only for RHEL/Centos
Convirture is alright, I'm actually surprised you had trouble importing. I think their update / patching process could be improved.
As reported in libvirtd official site there is basically two open source web interface for administering and manage libvirtd+KVM :
- AbiCloud
- oVirt
There is also other alternatives for administering and managing KVM through web interface, you can find a list at this address .
Maybe the best choice is RED HAT Enterprise Virtualization.
