This allows users to invoke xm against a remote server. This is much more
useful though for exercising XML-RPC transports with xm-test though since
xm-test will continue to (mostly) function if the URI is localhost.

This command proxies the Xend XML-RPC over stdio. This is similiar to
mercurial's hg serve --stdio command.
The most obvious use of this command is remote XML-RPC invocation over SSH.

This patch fixes a few bugs in the Python SimpleXMLRPC server and enables
HTTP/1.1 by default. This allows a client to use Keep-Alive. Keep-Alive
improves performance by eliminating the overhead of connection setup and,
more importantly, avoids credential caching when executing multiple
commands over a secure connection.

Lots of xm-test tests are failing with console timeouts on some machines
at the moment. I reproduced the problem and found it was due to some
probing activity in the boot process of the -xen kernel. The behaviour
of the current xm-test code is to assume that the boot process has
finished after performing three one-second waits for input---when the
probing activity introduces more than three one-second delays the test
suite breaks.
This patch changes the test suite to wait for the command prompt
before attempting to submit a command. The timeout is increased from 3
seconds to 3 minutes but the wait exits early when the prompt is found
so the test suite doesn't take any longer to run.

entry conditions to that function. Now that we no longer
check PGERR_page_present (i.e., that fault is a protection
fault), because it's not safe to do so, we can enter
ptwr_do_page_fault() with a not-present L2 page directory.
We then crash on our first access to the linear_l2_table.
This patch fixes all unprotected accesses to the
linear_l2_table to correctly handle faults.
Also move setup of globally-visible ptwr info record to end
of ptwr_do_page_fault(). We don't want the info picked up
by reentrant invocations of the page-fault handler.

The patch support ACPI UP Guest Windows 2000, XP and 2003, based on
this we are going to add more support on SMP and 64bit Windows( which
are only working in ACPI mode) later. We tested: in ia32 guest:
a. Installation and boot of Windows XP sp2 and 2003 server in ACPI
mode
b when boot to both window, no yellow mark in device manger and USB,
network card and IDE DMA are working.
c. clean boot (without ACPI related errors) on UP and 4 vcpu rhel4u1
SMP guest and got ioapic Interrupt assigned according to ACPI DSDT
table's _PRT table's GSI.
To minimize the implementation efforts to satisfy the ACPI OS
installation and boot, we implemented ACPI only event logical model by
emulating ACPI hardware based on PIIX4 (Intel 82371ab) by: Populating
the PIIX4 ACPI bridge PCI configuration space; Adding ACPI timer
(required during windows installation/boot), PM1 event register block
and PM1 control register block (both are required during
installation/boot, shutdown, entering and leaving PM S state if adding
those features later), we provided full ACPI hardware registers above
using byte/word/dword access per ACPI spec requirement.
The patch also fixed many existing hvm ACPI related bugs, such as
warnings when boot to ACPI UP and SMP guest Linux OS; adding new ACPI
_PRT table reporting PCI IRQ routing table in PIC mode, adding new _PRT
table in APIC mode, that fixed no IRQ GSI cause it is forced to shutdown
when OS find new device to assign IRQ without ACPI event service; The
patch also fixed the ACPI DSDT table's PCI resource conflict with guest
e820 table when booting and installing ACPI Windows; we also added ACPI
shutdown service by incorporating the code in ACPI "hardware enable
register writer" from Ben's Virtual Iron's team's patch in changeset
9989:f8d20c3e4225.
We only provide minimum power management requirement support per spec-c1
and S5 for shutdown, may be S4 (hibernating which is meaningful for user
to save their working section) in the future.
Please note, current patch needs to have following switches in guest
configuration to enable proper ACPI support
a. need to add ACPI=1 (apic=1 if boot SMP Linux guest plus vcpu=
number want to test) in xmexample.hvm
b. need to add USB support: USB=1 and usbdevice='device' (or
='tablet') as the pm register base is static..., I will adding dynamic
ACPI FADT table for pm register base pointer later.
When installing guest OS in ACPI mode, need to manually tell Windows
setup program to install single core ACPI HAL:
After passing the 1st screen of windows setup of install Windows,
the first thing you'll see at the bottom of the screen is the
option to press F6 if you need to install a SCSI or RAID
controller. Don't press F6. Press F5 instead. This will take
you to a separate menu of Hardware Abstraction Layer's where
you can choose an appropriate HAL .The choices will be:
ACPI Multiprocessor PC
ACPI Uniprocessor PC
Advanced Configuration and Power Interface (ACPI) PC
...
Standard PC
Standard PC with C-Step i486
Please select "Advanced Configuration and Power Interface (ACPI) PC"
using current patch.
