Hi, I've installed a OpenStack KILO all-in-one . For private need , I've to add a channel device to all my GUESTS on my compute node. It works fine (e.g. via a virsh command). Problem is that , in the xml describing the Guest , this 'state' value : <target type='virtio' name='agent' state='disconnected'/> showing if the channel is connected on the Guest side is missing. Does it mean that some qemu/KVM components are too old within KILO OpenStack release ? FYI , here are the installed related packages versions coming with KILO: libvirt-daemon-driver-qemu-1.2.8-16.el7_1.4.x86_64 libvirt-daemon-driver-storage-1.2.8-16.el7_1.4.x86_64 libvirt-python-1.2.8-7.el7_1.1.x86_64 libvirt-daemon-1.2.8-16.el7_1.4.x86_64 libvirt-gconfig-0.1.7-3.el7.x86_64 libvirt-client-1.2.8-16.el7_1.4.x86_64 libvirt-daemon-driver-nodedev-1.2.8-16.el7_1.4.x86_64 libvirt-daemon-config-network-1.2.8-16.el7_1.4.x86_64 libvirt-daemon-driver-network-1.2.8-16.el7_1.4.x86_64 libvirt-daemon-driver-nwfilter-1.2.8-16.el7_1.4.x86_64 libvirt-daemon-config-nwfilter-1.2.8-16.el7_1.4.x86_64 libvirt-glib-0.1.7-3.el7.x86_64 libvirt-daemon-driver-interface-1.2.8-16.el7_1.4.x86_64 libvirt-daemon-driver-secret-1.2.8-16.el7_1.4.x86_64 libvirt-gobject-0.1.7-3.el7.x86_64 libvirt-daemon-kvm-1.2.8-16.el7_1.4.x86_64 [root@localhost bin]# rpm -qa | grep kvm qemu-kvm-1.5.3-86.el7_1.8.x86_64 qemu-kvm-common-1.5.3-86.el7_1.8.x86_64 libvirt-daemon-kvm-1.2.8-16.el7_1.4.x86_64 [root@localhost bin]# rpm -qa | grep qemu libvirt-daemon-driver-qemu-1.2.8-16.el7_1.4.x86_64 qemu-guest-agent-2.1.0-4.el7.x86_64 qemu-kvm-1.5.3-86.el7_1.8.x86_64 qemu-img-1.5.3-86.el7_1.6.x86_64 qemu-kvm-common-1.5.3-86.el7_1.8.x86_64 qemu-img-1.5.3-86.el7_1.8.x86_64 ipxe-roms-qemu-20130517-6.gitc4bce43.el7.noarch Thanks for help, Regards, J.P.
