[libvirt-users] libvirt for spice

[suyi wang]

Hi all:

I tried kvm on my ubuntu  with the libvirt.xml file as follows:
   <domain type='kvm'>
       <name>instance-00000011</name>
       <memory>2097152</memory>
       <os>
               <type>hvm</type>
               <boot dev="hd" />
       </os>
       <features>
           <acpi/>
       </features>
       <vcpu>1</vcpu>
       <devices>
       <sound model='ac97'/>
       <input type='tablet' bus='usb'/>
           <disk type='file'>
               <driver type='qcow2'/>
               <source
   file='/opt/stack/nova/nova/../
/instances/instance-00000011/disk'/>
               <target dev='vda' bus='ide'/>
           </disk>
               <disk type='file'>
                   <driver type='qcow2'/>
                   <source

- Ignored:
   file='/opt/stack/nova/nova/..//instances/instance-00000011/disk.local'/>
                   <target dev='vdb' bus='ide'/>
               </disk>

           <interface type='bridge'>
               <source bridge='br100'/>
               <mac address='02:16:3e:44:a1:dd'/>
               <filterref
   filter="nova-instance-instance-00000011-02163e44a1dd">
                   <parameter name="IP" value="10.0.0.2" />
                   <parameter name="DHCPSERVER" value="10.0.0.1" />
               </filterref>
           </interface>

           <!-- The order is significant here.  File must be defined first
-->
           <serial type="file">
               <source
   path='/opt/stack/nova/nova/..//instances/instance-00000011/console.log'/>
               <target port='1'/>
           </serial>

           <console type='pty' tty='/dev/pts/2'>
               <source path='/dev/pts/2'/>
               <target port='0'/>
           </console>

           <serial type='pty'>
               <source path='/dev/pts/2'/>
               <target port='0'/>
           </serial>


           <graphics type='vnc' port='-1' autoport='yes' keymap='en-us'
   listen='0.0.0.0'/>

       </devices>
   </domain>

   So it works well.

   Howerver, I want change the remote access method by spice, I simply
changed
   the libvirt.xml as follows:
   <domain type='kvm'>
       <name>instance-00000011</name>
       <memory>2097152</memory>
       <os>
               <type>hvm</type>
               <boot dev="hd" />
       </os>
       <features>
           <acpi/>
       </features>
       <vcpu>1</vcpu>
       <devices>
       <sound model='ac97'/>
       <input type='tablet' bus='usb'/>
           <disk type='file'>
               <driver type='qcow2'/>
               <source
   file='/opt/stack/nova/nova/..//instances/instance-00000011/disk'/>
               <target dev='vda' bus='ide'/>
           </disk>
               <disk type='file'>
                   <driver type='qcow2'/>
                   <source
   file='/opt/stack/nova/nova/..//instances/instance-00000011/disk.local'/>
                   <target dev='vdb' bus='ide'/>
               </disk>

           <interface type='bridge'>
               <source bridge='br100'/>
               <mac address='02:16:3e:44:a1:dd'/>
               <filterref
   filter="nova-instance-instance-00000011-02163e44a1dd">
                   <parameter name="IP" value="10.0.0.2" />
                   <parameter name="DHCPSERVER" value="10.0.0.1" />
               </filterref>
           </interface>

           <!-- The order is significant here.  File must be defined first
-->
           <serial type="file">
               <source
   path='/opt/stack/nova/nova/..//instances/instance-00000011/console.log'/>
               <target port='1'/>
           </serial>

           <console type='pty' tty='/dev/pts/2'>
               <source path='/dev/pts/2'/>
               <target port='0'/>
           </console>

           <serial type='pty'>
               <source path='/dev/pts/2'/>
               <target port='0'/>
           </serial>


           <graphics type='spice' port='-1' autoport='yes' keymap='en-us'
   listen='0.0.0.0'/>

       </devices>
   </domain>

   As you can see, I just change <graphics type='vnc' port='-1'
autoport='yes'
   keymap='en-us' listen='0.0.0.0'/> to <graphics type='spice' port='-1'
   autoport='yes' keymap='en-us' listen='0.0.0.0'/>   ,   But it called the
   error as follows:

   libvirtError: internal error Process exited while reading console log
   output: char device redirected to /dev/pts/12
   TRACE: do_spice_init: starting 0.8.1
   TRACE: do_spice_init: statistics shm_open failed, Permission denied"


   I wish someone can give me some help! Thanks!
