spice channel, (document addr: http://
In short, it is a virtual serial port channel, to optimize some communication between the host and virtual machine.
After power up virtual machine, you will find some unknown devices in device manager.
we should install drivers for these devices (drivers download addr is http://
These drivers contain whole virtual graphics card driver, virtual network card driver and virtual serial port card driver.
this corresponds to the following libvirt XML:
<channel type='spicevmc'>
<target type='virtio' name='com.
<alias name='virserial
</channel>
video, this corresponds to the following libvirt XML:
<video>
<model type='qxl' vram='65536' heads='1'/>
</video>
sound, this corresponds to the following libvirt XML:
<sound model='ich6'>
<address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
</sound>
