This patch provide the code to set the VNC password to QEMU upstream through
VNC. The password is still stored in xenstore but will not be used by QEMU
upstream.

Add a memset to the save_callbacks struct instance in libcheckpoint's
initialization code. New additions to the callback struct will not
need to add an explicit initialization (to NULL), to maintain
compatibility with older xend/remus based invocation of xc_domain_save.

NetBSD libxc hypercall implementation was returning -errno on error,
instead of the actual error value from ioctl. Returning error is
easier to understand, and the caller can always check errno.

Currently guests created with the xl stack will have "xenbr0"
written as their default into xenstore. It can be changed in
the individual guest config files, but there is no way to
have that default globally changed.
Add a config option to xl.conf that allows to have a different
default bridge name.

This patch introduces configuration options allowing to built either a
rombios only or a seabios only hvmloader.
Building option ROMs like vgabios or etherboot is only enabled for a
rombios hvmloader, since SeaBIOS takes care or extracting option ROMs
itself from the PCI devices (these option ROMs are provided by the
device model and do not need to be built in hvmloader).
The Makefile in tools/firmware/ now only checks for bcc if rombios is
enabled.
These two configuration options are left on by default to remain
compatible.

Make load_rom field in struct bios_config an optionnal callback rather
than a boolean value. It allow BIOS specific code to implement it's
own option ROM loading methods.
Facilities to scan PCI devices, extract an deploy ROMs are moved into

To remain consistent with how other ROMs are built into hvmloader,
call mkhex on etherboot ROMs from the hvmloader directory, instead of
the etherboot directory. In other words, eb-roms.h is not used any
more.
Introduce ETHERBOOT_NICS config option to choose which ROMs should be
built (kept rtl8139 and 8086100e per default as before).

Per page operations in the paging, sharing, and access tracking subsystems are
all implemented with domctls (e.g. a domctl to evict one page, or to share one
page).
Under heavy load, the domctl path reveals a lack of scalability. The domctl
lock serializes dom0's vcpus in the hypervisor. When performing thousands of
per-page operations on dozens of domains, these vcpus will spin in the
hypervisor. Beyond the aggressive locking, an added inefficiency of blocking
vcpus in the domctl lock is that dom0 is prevented from re-scheduling any of
its other work-starved processes.
We retain the domctl interface for setting up and tearing down
paging/sharing/mem access for a domain. But we migrate all the per page
operations to use the memory_op hypercalls (e.g XENMEM_*).

If a page is nominated but not evicted,then dom0 accesses the page,it
will change the page's p2mt to be p2m_ram_paging_in,and the req.flags
is MEM_EVENT_FLAG_EVICT_FAIL;so it will fail in p2m_mem_paging_evict()
because of the p2mt;and paging->num_paged_out will not increase in
this case;After the paging process is terminated, the p2mt
p2m_ram_paging_in still remains in p2m table.Once domU accesses the
nominated page,it will result in BSOD or vm'stuck.
The patch adds the dealing of this request to resume the page before
xenpaging is ended.
[ This can happen if p2m_mem_paging_populate() was called by a foreign
domain. In this case MEM_EVENT_FLAG_VCPU_PAUSED is not set and xenpaging
will not sent a response. And in this case the ring is in an
inconsistent state anyway, new requests cant be added, I think. - Olaf ]

When bootloader_args = ['foo', 'bar'], then info->u.pv.bootloader_args =
foo\0
bar\0
\0
Before this patch, 'p++' points to the next character of 'foo\0' and never
comes to 'bar\0' (because of the '\0' in 'foo\0'), so the args will be:
args[0] = 'oo\0'
args[1] = 'o\0'
After this patch, 'p++' points to the next string of pv.bootloader_args, so we
get the correct args:
args[0] = 'foo\0'
args[1] = 'bar\0'
