[one-users] Failed to create Domain

[Javier Fontan]

Hello,

This is the working configuration I have in an Ubunutu 12.04:

* Packages:

openssh-client
openssh-server
libvirt-bin
qemu-kvm
ruby

* /etc/apparmor.d/local/usr.sbin.libvirtd

--8<------
/var/lib/one/** lrwk,
------>8--

* /etc/libvirt/qemu.conf

--8<------
# The user ID for QEMU processes run by the system instance.
#user = "root"
user = "oneadmin"

# The group ID for QEMU processes run by the system instance.
#group = "root"
group = "oneadmin"

# Whether libvirt should dynamically change file ownership
# to match the configured user/group above. Defaults to 1.
# Set to 0 to disable file ownership changes.
#dynamic_ownership = 1
dynamic_ownership = 0
------>8--

* /etc/libvirt/libvirtd.conf

--8<------
listen_tls = 0
listen_tcp = 1
unix_sock_group = "libvirtd"
unix_sock_rw_perms = "0770"
mdns_adv = 0
auth_unix_ro = "none"
auth_unix_rw = "none"
------>8--

* oneadmin extra groups

usermod -a -G libvirtd,kvm oneadmin


Make sure you restart all the daemons, reload apparmor and reload kvm
modules so thy have the correct permissions. Maybe is just easier to
restart the machine.
