kvm, hal, and evdev

kvm, hal, and evdev

[Alan Kennedy]

Hi,

When using hal to autoload the mouse and keyboard with evdev. The evdev keyboard
model does not work correctly with kvm (qemu) hosts. The arrow, home, end,
insert & delete keys are mapped incorrectly or do not work at all. 

This is not unique to kvm (qemu), and also occurs with vmware. See url below for
vmware work around. Found this on the net. 

http://communities.vmware.com/message/498632

I suspect the problem is with evdev, but not sure. Is there any work around like
used in vmware or other solutions?

My solution was stop using hal input autoloading with evdev, and everything is
working fine now. However, I would like to start using evdev if possible because
that is the only driver that fully supports my mouse. 

Thanks for any help with this matter.

Alan

System details:

Kernel 2.6.25.4
QEMU PC emulator version 0.9.1 (kvm-69)

How are you interacting with the guest?  via SDL?  If so, do other SDL 
applications work correctly?  Are you using evdev in the host or in the 
guest?

Thanks for the response. 

I'm using SDL. I have no other SDL applications. If you know of a easy to
install SDL application to use as a test please let me know. 

The host is running evdev, and the guest is Windows XP. 

Thanks again,

Alan

Historically, SDL has had some trouble processing input events.  I 
wouldn't be surprised if it's evdev support was buggy.  See if you see 
have problems using -vnc and connecting with a vnc client (preferrably, 
vinagre or gvncviewer).
