The console /dev/pts paths are allocated by the kernel on the fly each time a VM starts, so it is expected that this will vary. The '<target dev='vnet0'>' element refers to an auto-generated Xen backend device name, and again this is expected to change, and only be visible when the guest is running. So all the differences you see are expected. FYI, if you run 'virsh dumpxml --inactive GUEST' you will be shown the static configuration which should exclude all these runtime auto-generated attributes. Thanks for explaining, Daniel. I think this bug can be closed as invalid. Closing at reporter's request. |
Description of problem: Using virt-manager, I added a gfx head to a VM that didn't have one previously. Looking at the resulting xml, it also changed some of the serial config. This seems harmless but unexpected. --- 1 2009-07-06 16:20:40.000000000 -0400 +++ 2 2009-07-06 16:20:43.000000000 -0400 @@ -36,13 +36,15 @@ <model type='virtio'/> </interface> <serial type='pty'> - <source path='/dev/pts/2'/> + <source path='/dev/pts/3'/> <target port='0'/> </serial> - <console type='pty' tty='/dev/pts/2'> - <source path='/dev/pts/2'/> + <console type='pty' tty='/dev/pts/3'> + <source path='/dev/pts/3'/> <target port='0'/> </console> + <input type='mouse' bus='ps2'/> + <graphics type='vnc' port='-1' autoport='yes' listen='127.0.0.1' keymap='en-us'/> </devices> </domain> then I removed the gfx head and it also removed a snippet from the network section.
