AttributeError: Tree instance has no attribute 'kvc'

after giving 'kss' rights to write into '/etc/libvirt'

chris:/etc/libvirt # l total 37 drwxrws--- 4 root kss 184 Aug 9 11:25 ./ drwxr-xr-x 131 root root 8584 Aug 7 11:33 ../ -rw-r--r-- 1 root root 10748 Aug 8 16:46 libvirtd.conf -rw-r--r-- 1 root root 534 Feb 8 2012 lxc.conf drwxrwx--- 2 root root 640 Aug 10 10:31 nwfilter/ drwxrwx--- 4 root kss 96 Aug 10 10:35 qemu/ -rw-r--r-- 1 root root 9699 Feb 8 2012 qemu.conf

How to fix this ?

Hi,

Which hypervisor are you using, either KVM or Xen?

To make sure which to use, try the commands below:

$ lsmod | grep kvm
and
$ ls -ld /proc/xen

I'm using xen, but karesansui is not installed on the 'hypervisor host'. It is installed on a "management host". Is it a 'must' for karesansui to be installed on the hypervisor host ?

Hello,

Is it a 'must' for karesansui to be installed on the hypervisor host ?

Yes, it is. To set up Karesansui, a hypervisor must be running on the host where it is gonna be installed.

[taizo]

I close the issue for now.

I may be wrong, but 'main comunication' is done via libvirt, isn't it. So wouldn't it be enough just having "libvirt" installed on the karesansui host ? This would keep your Virtualization Host "clean".
