Recent changes to the setup of the peth0 interface have resulted in a

address of 'fe:ff:ff:ff:ff:ff', but now it has the same MAC address as
eth0. As a consequence to this the Xen-API code to create VLANs

not be identified according to this previous criteria of fake MAC
address. This patch fixes this issue by identifying it through the
prefix 'peth'.

[IA64] Enable Xen VGA autodetection
This patch enables console autodetection for VGA on systems
implementing a PCDP table. With this, setting the primary console to
VGA or serial will cause both Xen and Dom0 output to go to the right

This shouldn't help or hurt systems without an HCDP/PCDP table.

[IOEMU] Fix shift key for graphical vnc display
There is a problem in the input of the key in the VNC connection on
the HVM domain. When client's keyboard is not the same as the kind of
the keyboard of qemu-dm and GuestOS, it is not possible to input it
correctly.
VNC client qemu-dm & GuestOS
--------------+-----------------------
ja en-us ==> NG
en-us en-us ==> OK
Originally, the same keysym-code between client and qemu-dm is
transmitted. However, even if it is the same character, the state of
shift is different according to the kind of keyboard.
ex.
"=" charactor
---------------------
en-us : "="
ja : shift + "-"
Therefore, it is necessary to handle the state of the shift by setting
qemu-dm and GuestOS. There is information on whether shift is
necessary for each key for the keymap of qemu-dm.
ex.
VNC client : ja
qemu-dm & GuestOS : en-us
input key : "="
event client to qemu-dm :
shift(push) >> "="(push) >> "="(release) >> shift(release)
event qemu-dm to guest :
shift(push) >> shift(release) >> "="(push) >> "="(release) >>
shift(push) >>
shift(release)
This patch handled the state of shift from the set keymap.
When client's keyboard is not same as the kind of qemu-dm/GuestOS,
it is possible to input it correctly.
It was confirmed to input it correctly mutually with this patch
between en-us and ja.
