spice can't support usb redirection

[wang jiedong]

I have a environment of Newton in ubuntu16.04, every component that i install is ok ,
then i build a vm with spice proxy,the configurations in nova.conf like :

[spice]
enabled = True
agent_enabled = True
server_listen = 0.0.0.0
server_proxyclient_address = $my_ip
html5proxy_base_url = http://$my_ip:6082/spice_auto.html

of course the console is also ok ,but when i want transfer some doc to vm from client usb, vm can't find the usb device
there is nothing about usb in vm.xml :

Fix proposed to branch: stable/newton
Review: https://review.openstack.org/397635

[Matt Riedemann (mriedem)]

Do you see warnings in the nova-compute logs when creating the guest?

What do you have set for the use_usb_tablet and pointer_model config options?

What is the libvirt.virt_type value in your nova.conf?

See the config docs for more information on those options:

http://docs.openstack.org/developer/nova/sample_config.html

[wang jiedong (jeery)]

sorry ,i think i didn't describe it clearly, the virt_type is kvm, and a parameter usbredir_channels is added in nova.conf after spice section, my total nova.conf like this:

[DEFAULT]
dhcpbridge_flagfile=/etc/nova/nova.conf
dhcpbridge=/usr/bin/nova-dhcpbridge
log-dir=/var/log/nova
state_path=/var/lib/nova
force_dhcp_release=True
verbose=True
ec2_private_dns_show_ip=True
enabled_apis=osapi_compute,metadata

transport_url = rabbit://openstack:RABBIT_PASS@newtu
auth_strategy = keystone
my_ip=192.168.178.24
use_neutron = True
firewall_driver = nova.virt.firewall.NoopFirewallDriver

[vnc]
enabled = False
vncserver_listen = 0.0.0.0
vncserver_proxyclient_address = $my_ip
novncproxy_base_url = http://$my_ip:6080/vnc_auto.html

[spice]
enabled = True
agent_enabled = True
server_listen = 0.0.0.0
server_proxyclient_address = $my_ip
html5proxy_base_url = http://$my_ip:6082/spice_auto.html
usbredir_channels = 4

[database]
connection = mysql+pymysql://nova:NOVA_DBPASS@newtu/nova

[api_database]
connection = mysql+pymysql://nova:NOVA_DBPASS@newtu/nova_api

[oslo_concurrency]
lock_path=/var/lock/nova/tmp

[libvirt]
use_virtio_for_bridges=True

[wsgi]
api_paste_config=/etc/nova/api-paste.ini

[keystone_authtoken]
auth_uri = http://newtu:5000
auth_url = http://newtu:35357
memcached_servers = newtu:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = nova
password = nova

[glance]
api_servers = http://newtu:9292

[neutron]
url = http://newtu:9696
auth_url = http://newtu:35357
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = neutron
service_metadata_proxy = True
metadata_proxy_shared_secret = METADATA_SECRET

[cinder]
os_region_name = RegionOne

then, in the VM's XML i can find usb channels :

    <redirdev bus='usb' type='spicevmc'>
      <alias name='redir0'/>
    </redirdev>
    <redirdev bus='usb' type='spicevmc'>
      <alias name='redir1'/>
    </redirdev>
    <redirdev bus='usb' type='spicevmc'>
      <alias name='redir2'/>
    </redirdev>
    <redirdev bus='usb' type='spicevmc'>
      <alias name='redir3'/>
    </redirdev>
