Public bug reported:
I am working on setting up Edubuntu 11.10 as a paravirtualized Xen
guest. I installed linux-image-3.0.0-16-virtual on the guest VM, but
found that the xen-kbdfront module was missing. According to the
provided kernel configs, the Xen PV keyboard frontend is compiled as a
module in both linux-image-3.0.0-12-generic and linux-
image-3.0.0-16-virtual:
root@ltsp2:/# grep CONFIG_INPUT_XEN_KBDDEV_FRONTEND /boot/config-3.0.0-1*
/boot/config-3.0.0-12-generic:CONFIG_INPUT_XEN_KBDDEV_FRONTEND=m
/boot/config-3.0.0-16-virtual:CONFIG_INPUT_XEN_KBDDEV_FRONTEND=m
The xen-kbdfront module is provided with linux-image-3.0.0-12-generic
but missing in linux-image-3.0.0-16-virtual:
root@ltsp2:/# locate xen-kbd
/lib/modules/3.0.0-12-generic/kernel/drivers/input/misc/xen-kbdfront.ko
root@ltsp2:/# ls /lib/modules/3.0.0-16-virtual/kernel/drivers/input/
evbug.ko gameport joydev.ko mouse serio touchscreen
This means that if I boot the VM using the "virtual" image and try to
access the VM's console through VNC, the keyboard and mouse don't work.
With the "generic" image, I can load the xen-kbdfront module and the
keyboard and mouse work fine.
