I defined a cdrom to a guest domain as follows.
",hdc:cdrom,r"
When the guest domain was created by using xm create command, uname
of the cdrom was ''. Then creating the guest domain succeeded.

<<snip>>
['device', ['vbd', ['uname', ''], ['dev', 'hdc:cdrom'], ['mode',
'r']]],
<<snip>>
But, when the guest domain was created by using virsh start command,
uname of the cdrom was None. Then creating the guest domain failed.

On AMD cpus, HVM S3 resume was hanging in the bios when trying
to load the x_firmware_waking_vector from absolute
address 0xEA01C (that is, a segment offset greater than 64kB).
This change also now uses 20-bits (instead of 16) from the FACS
standard firmware_waking_vector.

Domctl interface is extended to allow libxc retrieve device group
information from hypervisor. Vendor-specific iommu_ops is also
extended by adding a new operation "get_device_group_id()", which is
currently a null pointer but could be implemented later for vt-d.
Error will be raised from tools side when user trying to assign PCI
device with a sibling device being driven by dom0. User will keep
being prompted until he has hidden the entire device group (at least,
the sibling devices driven by dom0) in dom0 kernel
parameter. Hopefully this framework could be flexible enough to
support both amd iommu and vt-d.
The following 2 cases are not covered by this patch, but should be
easy to handle.
* Checking for hot-plug devices (maybe we can delay calling
ImageHandler.signalDeviceModel() until all checks are done?)
* Checking for splitted device group between different passthru
domains

This patch adds -s --ssl option to xm migrate. It will override
xend-relocation-ssl setting in /etc/xen/xend-config.sxp.

This patch makes ssl relocation server listen on 8003 if enabled.
Whether to start ssl relocation server now controlled by
xend-relocation-ssl-server. So ssl and non-ssl relocation server can
run simultaneously. You can also only start ssl server or only start
non-ssl relocation server.
When mix deploy xen 3.2 server (has no ssl support) and 3.3 servers,
start ssl and non-ssl relocation server simultaneously can keep
backward compatibility.
It's also more reasonable to have separate ports for ssl and non-ssl.
In this patch, also renames xend-relocation-tls to xend-relocation-ssl.

The automatic NUMA placement code (find_relaxed_node) in
XendDomainInfo.py contains several bugs:
1. The domain just created shall not be considered in the load
calculation.
2. Nodes with too less memory for the domain must be considered during
the load calculation phase and abandoned later, currently these nodes
win with a load of 0.
3. CPUs which are offline shall not be considered in load calculation.
4. (Integer-)Dividing the load value by the number of cores per node
may conceal subtle load differences resulting in a non-optimal node to
be chosen.

- add S3 package in ACPI DSDT table. Guest OS will get S3 value from
this package and write the value to PM1A control register to
trigger S3 suspend.
- Add S3 resume logic in rombios post code. the CMOS shutdown register
is used to indicate if this is a S3 resume.
- if it is s3 resume, rombios will get wakeup vector from ACPI FACS
table and jump to wakeup vector. Per ACPI spec, the wakeup vector
jumping must be the forms CS:IP, in which CS=3D(wakeup vector>>4)
IP=3D(wakeup vector)&0xF, for example, for vector=3D0x12345,
CS:IP=3D0x1234:0x5
Note: clobber_entry_point will clobber the post entry, which make S3
resume not work. We will directly jmp to POST Entry if it in S3

(1) A typo in serial_save() where qemu_get_8s is called (should be
qemu_put_8s)
(2) No support provided in serial_load() for version_id == 1 (should
unmarshal a 1 byte s->divider and should provide a default value
for s->fcr)
(3) Call serial_ioport_write() to initialize s->fcr. It is not
sufficient to load its value; other hidden values (such as
s->recv_fifo.itl) must be re-initialized.

The protocol field of the blkif interface is correct at startup for a

However, this property is not persisted on save, so a later restore

[PVFB] Fix shift key for graphical vnc display.
With above patch, if a user presses shift-insert, qemu sends shift
down, shift up, insert down and then another shift key down (see trace
below). This makes it impossible to do shift insert pasting or use
guest hot shifted-Fkeys.
Shift Insert trace:
do_key_event():1135 keycode:2a shift down
kbd_put_keycode():539 keycode:2a send shift down
do_key_event():1135 keycode:d2 insert down
kbd_put_keycode():539 keycode:aa send shift up
kbd_put_keycode():539 keycode:e0 send insert down
kbd_put_keycode():539 keycode:52
do_key_event():1135 keycode:d2 insert up
kbd_put_keycode():539 keycode:e0 send insert up
kbd_put_keycode():539 keycode:d2
kbd_put_keycode():539 keycode:2a send shift down
do_key_event():1135 keycode:2a shift up
kbd_put_keycode():539 keycode:aa send shift up
This patch adds a check for the keycode being shiftable, something
other than a keypad key, f1-12 , insert, del , etc. before allowing
the press_shift_up() operation.
