When I tried to use QCow image, I found that only each second boot is
successful. As I discovered, this is caused by wrong handling old qcow
tapdisk images. Extended header flag is not stored correctly so the
blktap tries to change endian fo L1 table on each startup.

If a domain has no videoram (say, dom0), then treat the size as 0 and
continue, rather than just failing.

If you enable legacy tcp xmlrpc in xend's config but omit to enable

When cloning kernel repo:
1. make remote called "xen" rather than the default "origin"
2. directly checkout the desired branch, rather than the default
then the desired one
Git 1.5 doesn't support -b on git clone, and seems to do something odd
with the checkout branch argument, so avoid using the newer
commandline options.

PAT caching was only propagated if has_arch_pdevs(),
causing the hvm_get_mem_pinned_cacheattr() to be ignored
in the non passthrough case.
l1_disallow_mask() needs to be relaxed.

Quoting the original Linux patch's description:
"This patch adds a extended crashkernel syntax that makes the value of
reserved system RAM dependent on the system RAM itself:
crashkernel=3D<range1>:<size1>[,<range2>:<size2>,...][@offset]
range=3Dstart-[end]
For example:
crashkernel=3D512M-2G:64M,2G-:128M
The motivation comes from distributors that configure their
crashkernel command line automatically with some configuration tool
(YaST, you know ;)). Of course that tool knows the value of System
RAM, but if the user removes RAM, then the system becomes unbootable
or at least unusable and error handling is very difficult."
For x86, other than Linux we pass the actual amount of RAM rather than
the highest page's address (to cope with sparse physical address
maps).
This still needs to be hooked up for ia64.

The previous scheme --- freeing an area of BSS --- did not interact
nicely with device passthrough as IOMMU will not have any Xen BSS area
in guest device pagetables. Hence if the freed BSS space gets
allocated to a guest, DMAs to guest's own memory can fail.
The simple solution here is to always free the static buffer at end of
boot (initmem is specially handled for IOMMUs) and require a
dynamically-allocated buffer always to be created.

xenstore to release the resource allocated in backend driver
lies in dom0'kernel
Blktapctl thread will use qemu-dm connection instead of tapdisk-ioemu
in the case of FV VM. We found the resource like memory allocated for
this Guest can't be free for backend driver couldn't be closed in qemu-dm.
This patch would remove the backend of tapdisk device earlier in
xenstore to triger qemu-dm to notify the backend driver to release the
resource allocated.
I have tested this patch at the case of
1, save && restore
2, destory && shutdown
3, snapshot

If domain creation in xend fails before devices are configured, e.g.
insufficient memory, device config is dropped from xend's managed
domain config.
Once xend is restarted, the domain's devices are lost.
This patch fixes a bug in XendConfig where only the device
controller was consulted for device configuration.

The info subcommand was missing from the xl tool. Use the new libxl
wrapper functions to create a clone of "xm info". The splitting into
several smaller functions is enspired by the implementation in
