If users require domain memory size larger than a physical memory
size, we do not need waiting for ballooning, and should cause
xm create command error right away.

On systems where the grub bootloader is not available or active the
to-be-activated policy is written a simple textfile. Once xend has
started the contents can be read. Using 'xm setpolicy' the policy can
be activated and the Domain-0 label set (using 'xm addlabel').
I fixed some bugs in the grub bootloader handler on the way and
removed some dead functions.

I have added CONFIG_PASSTHROUGH in ioemu/Makefile.target and
ioemu/hw/pc.c in attached vtd_tools2.patch. This should turn off
libpci usage by default until user specifically enables it.
This can be safely check-in without breaking builds for people who do
not care about pass-through devices. I will try to think of a better
way to enable this.

I found that xend's memory usage grows considerably when running a
script such as
while true; do xm new foo ; sleep 2s; xm delete foo ; sleep 2s; done
XendAPIStore maintains a list of class instances and in the case of
new/create operation, an associated VMMetrics object is stashed in the
list but never removed on delete/shutdown. This patch removes the
instance by invoking XendBase.destroy() method.

This patch adds 'type vnc' to vfb device sexpr for HVM guests. PV
guests already contain this entry in sexpr, e.g.
(device
(vfb
(vncunused 1)
...
(type vnc)
...
)
)
Some tools, such as libvirt, look for device/vfb/type in sexpr before
publishing VNC port. More importantly, this patch provides
consistency in vfb device sexpr between HVM and PV guests.

- Wait time
When xm requests a block device detach to xend, xm makes two
requests. At first, xm requests the block device detach by device
class 'vbd'. Next, xm requests the block device detaching by
device class 'tap'.
As a result, the wait time is 200 seconds because each of
the block device detaching requests causes time-out.
- Misleading error message
Because the last request is by device class 'tap' to xend,
the keyword "(tap)" is included in the error message.
This patch fixes the number of times of the block device detaching
request to one time. At first, xm makes inquiries about device
class of a detaching target device to xend. Then xm requires the
block device detaching by xend returned device class. The wait
time becomes 100 seconds because the block device detaching request
is one time. And the error message is also fixed.

When I tested xm trigger command with a wrong argument, I saw the
following error message.
# xm trigger vm1 xyz
Error: __init__() takes exactly 2 arguments (3 given)
Usage: xm trigger <Domain> <nmi|reset|init> [<VCPU>]
Send a trigger to a domain.
This patch fixes the error message as follows.
# xm trigger vm1 xyz
Error: Invalid trigger: xyz
Usage: xm trigger <Domain> <nmi|reset|init> [<VCPU>]
Send a trigger to a domain.
The type of "TRIGGER_TYPE" is dictionary. domain_send_trigger()

When I tested xm create command, I saw the following error message.
I expected an error message "Error: (12, 'Cannot allocate memory')"
because I intentionally caused a memory shortage on the test.
But the error message was different from my expectation.
# xm create /xen/HVMdomain.1
Using config file "/xen/HVMdomain.1".
Error: an integer is required
I looked at xend.log to examine the cause why the error message was
shown. (Could you see the attached xend.log?)
xend had the error message "Error: (12, 'Cannot allocate memory')"
first. But xend changed the error message to "Error: an integer is
required" halfway. I'm not sure about the cause why an exception
occurred in logging processing. But when I applied an attached patch,
I confirmed that the error message that I expected was shown. The
patch does not call xc.domain_destroy_hook() if self.domid is None.

The basic problem was that the "image" section of the sxp had a "None"
in it, which means that on the restore (either on the local machine or
remote machine), the vnc server in the qemu device model literally
needed the string "None" to properly connect. This simple patch only
puts a vncpasswd entry in the image if it is *not* None in the python
code, thus avoiding the whole issue.

On my FC7 installation some of the test in the xm test suite fail for
no apparent reason. The problem is that the python 'readline' module
puts out control characters that confuse code that parses the output
of some of the xm commands that are being run. The readline module
dumps those characters upon import. The attached patch works around
this problem.
Here's what I get in out.txt when doing 'python 2>&1 | tee out.txt'
and 'import readline' on the python command line:
Python 2.5 (r25:51908, Apr 10 2007, 10:29:13)
[GCC 4.1.2 20070403 (Red Hat 4.1.2-8)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
[[?1034h>>> >>>
The characters before the '>>>' above are those printed by that
version of 'readline' and remain invisible on the screen but appear in
the file and confuse the xm test suite parser.

When calling destroyDevice code path (e.g. xm block-detach dom devid),
allow specifying an integer device id or a device name such as xvdN or
/dev/xvdN. Allowing the /dev/xvdN form is useful when detaching
devices from dom0. Bootloaders may do this to unmount a disk
previously mounted in dom0.
Move examination of device ID format into the DevController,
permitting device controllers to determine a valid device ID instead
of higher level code.

Add support for removing/replacing a policy from the running
system. This operation is only successful if currently running VMs
would also be allowed to run under the new policy. Removing the
current policy means that the default policy is installed, which then
only has support for a single VM label and STE type (SystemManagement)
and is the same policy that the system starts up with when no policy
is chosen.

Xend tries to rebuild the network configuration such as bridges and
vlan interfaces (in those bridges) when starting. Unfortunately this
fails on the first startup since the network script has not run, yet,
and for example created peth0. When restarting xend it works due to
the peth0 being there then. This patch moves the initialization of the
network to an earlier time in the xend initialization process to
mitigate this problem.

Recent changes to the setup of the peth0 interface have resulted in a
change of its MAC address. Previously it seems to have had a MAC
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
(PIF.create_VLAN("peth0",...)) does not work anymore, since peth0 can
not be identified according to this previous criteria of fake MAC
address. This patch fixes this issue by identifying it through the
prefix 'peth'.
