[libvirt-users] libvirt for spice
by suyi wang 07 Mar '12

07 Mar '12

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>  <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>  <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!
