Hi, I’m trying to add a channel on a Openstack instance via this command : # virsh attach-device instance-00000005 test.xml that returns this error error: Failed to attach device from test.xml error: internal error: no virtio-serial controllers are available # # cat test.xml : <channel type='unix'> <source mode='bind' path='//var/lib/libvirt/qemu/instance-00000005.agent'/> <target type='virtio' name='instance-00000005.agent'/> </channel> #virsh dumpxml instance-00000005 <domain type='kvm' id='8'> <name>instance-00000005</name> <uuid>f85ea8a4-0159-417c-bef5-5b4e908ea2a0</uuid> <metadata> <nova:instance xmlns:nova="http://openstack.org/xmlns/libvirt/nova/1.0"> <nova:package version="12.0.1-1.el7"/> <nova:name>Fedora-Cloud-23-2015-1</nova:name> <nova:creationTime>2016-06-06 08:22:34</nova:creationTime> <nova:flavor name="m1.small"> <nova:memory>2048</nova:memory> <nova:disk>20</nova:disk> <nova:swap>0</nova:swap> <nova:ephemeral>0</nova:ephemeral> <nova:vcpus>1</nova:vcpus> </nova:flavor> <nova:owner> <nova:user uuid="da49c3189eaf40b28893b422b60cc73e">demo</nova:user> <nova:project uuid="ef3ecf8618e24130b2cd8adab8e17310">demo</nova:project> </nova:owner> <nova:root type="image" uuid="a22e881e-dd17-4795-a118-67f9ec90a768"/> </nova:instance> </metadata> <memory unit='KiB'>2097152</memory> <currentMemory unit='KiB'>2097152</currentMemory> <vcpu placement='static'>1</vcpu> <cputune> <shares>1024</shares> </cputune> <resource> <partition>/machine</partition> </resource> <sysinfo type='smbios'> <system> <entry name='manufacturer'>Fedora Project</entry> <entry name='product'>OpenStack Nova</entry> <entry name='version'>12.0.1-1.el7</entry> <entry name='serial'>8cd9a34f-a760-4c53-9420-a3a22a484bb2</entry> <entry name='uuid'>f85ea8a4-0159-417c-bef5-5b4e908ea2a0</entry> <entry name='family'>Virtual Machine</entry> </system> </sysinfo> <os> <type arch='x86_64' machine='pc-i440fx-rhel7.0.0'>hvm</type> <boot dev='hd'/> <smbios mode='sysinfo'/> </os> <features> <acpi/> <apic/> </features> <cpu mode='host-model'> <model fallback='allow'/> <topology sockets='1' cores='1' threads='1'/> </cpu> <clock offset='utc'> <timer name='pit' tickpolicy='delay'/> <timer name='rtc' tickpolicy='catchup'/> <timer name='hpet' present='no'/> </clock> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>destroy</on_crash> <devices> <emulator>/usr/libexec/qemu-kvm</emulator> <disk type='file' device='disk'> <driver name='qemu' type='qcow2' cache='none'/> <source file='/var/lib/nova/instances/f85ea8a4-0159-417c-bef5-5b4e908ea2a0/disk'/> <backingStore type='file' index='1'> <format type='raw'/> <source file='/var/lib/nova/instances/_base/5773dfb9c65f9640334bf9b3101ac8a2f485ee83'/> <backingStore/> </backingStore> <target dev='vda' bus='virtio'/> <alias name='virtio-disk0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/> </disk> <controller type='usb' index='0'> <alias name='usb'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x2'/> </controller> <controller type='pci' index='0' model='pci-root'> <alias name='pci.0'/> </controller> <interface type='bridge'> <mac address='fa:16:3e:ad:2d:51'/> <source bridge='qbr9ece405a-26'/> <target dev='tap9ece405a-26'/> <model type='virtio'/> <alias name='net0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> <serial type='file'> <source path='/var/lib/nova/instances/f85ea8a4-0159-417c-bef5-5b4e908ea2a0/console.log'/> <target port='0'/> <alias name='serial0'/> </serial> <serial type='pty'> <source path='/dev/pts/4'/> <target port='1'/> <alias name='serial1'/> </serial> <console type='file'> <source path='/var/lib/nova/instances/f85ea8a4-0159-417c-bef5-5b4e908ea2a0/console.log'/> <target type='serial' port='0'/> <alias name='serial0'/> </console> <input type='tablet' bus='usb'> <alias name='input0'/> </input> <input type='mouse' bus='ps2'/> <input type='keyboard' bus='ps2'/> <graphics type='vnc' port='5901' autoport='yes' listen='0.0.0.0' keymap='en-us'> <listen type='address' address='0.0.0.0'/> </graphics> <video> <model type='cirrus' vram='16384' heads='1'/> <alias name='video0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </video> <memballoon model='virtio'> <stats period='10'/> <alias name='balloon0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/> </memballoon> </devices> <seclabel type='dynamic' model='selinux' relabel='yes'> <label>system_u:system_r:svirt_t:s0:c699,c952</label> <imagelabel>system_u:object_r:svirt_image_t:s0:c699,c952</imagelabel> </seclabel> </domain> How may I add this controller ( before adding the channel device) ?
