[Kimchi-devel] [PATCH] test_model: using default pool in test_vm_disk

[Ramon Medeiros]

Hi Aline,

until now, the only way i fixed this is changing this property:

[root at localhost tests]# cat /etc/libvirt/qemu.conf | grep root
user = "root"
group = "root"

So instead of running user qemu on libvirt, i started running user root. 
Then the test went right.

I will take a look to change the test and force to create everything as 
qemu user
