Description Cui Chun 2011-01-21 07:20:49 UTC

Description of problem:

libvirt unsupported graphics types include 'sdl', 'rdp', 'desktop'. 

'sdl' error message has been fixed in bug 633326. However, the error message for 'rdp' and 'desktop' are different from 'sdl'  

Version-Release number of selected component (if applicable):
libvirt-0.8.7-3.el6
qemu-kvm-0.12.1.2-2.129.el6


How reproducible:
Always

Steps to Reproduce:

1. Configure rdp and desktop respectively by changing the guest's XML from
    <graphics type='vnc port='-1' autoport='yes' listen='0.0.0.0'
keymap='en-us'/>
to
    <graphics type='rdp'>

    <graphics type='desktop'>

2. Start the guest and check error message


Actual results:

# virsh start cc
error: Failed to start domain cc
error: internal error unsupported graphics type 'desktop'

# virsh start cc
error: Failed to start domain cc
error: internal error unsupported graphics type 'rdp'


Expected results:

Output the uniform error message with 'sdl'.

Additional info:

The error message for 'sdl' are:

# virsh start cc
error: Failed to start domain cc
error: unsupported configuration: sdl not supported by '/usr/libexec/qemu-kvm'
