`xenpvnetboot' supports getting boot images from following locations:
- http://host/path
- https://host/path
- ftp://host/path
- file:///path
- tftp://host/path
- nfs:host:/path
- /path
- /path/file.iso
- /path/filesystem.img
- /dev/sda1
- nfs+iso:host:/path/file.iso
- nfs+iso:host:/path/filesystem.img
To use it, make `xenpvnetboot' as bootloader for PV guest::
bootloader = '/usr/bin/xenpvnetboot'
To get boot images from various locations, set the right bootloader
arguments, e.g.:
bootloarder_args = ['--location=http://192.168.0.1/fedora/x86_64']
bootloarder_args = ['--location=ftp://192.168.0.1/fedora/x86_64']
bootloarder_args = ['--location=file:///fedora/x86_64']
bootloarder_args = ['--location=tftp://192.168.0.1/fedora/x86_64']
bootloarder_args = ['--location=/fedora/x86_64']
bootloarder_args = ['--location=/fedora/Fedora-16-x86_64-DVD.iso']
bootloarder_args = ['--location=nfs:192.168.0.1:/fedora/x86_64']
bootloarder_args = ['--location=nfs+iso:192.168.0.1:/fedora/Fedora-16-x86_64-DVD.iso']
You can use `kernel' and `ramdisk' to specify the relative path of
boot kernel and ramdisk. `xenpvnetboot' will join them with the
location to find the boot kernel and ramdisk, e.g.:
kernel = 'images/pxeboot/vmlinuz'
ramdisk = 'images/pxeboot/initrd.img'
bootloarder_args = ['--location=http://192.168.0.1/fedora/x86_64']
kernel = 'fedora/x86_64/images/pxeboot/vmlinuz'
ramdisk = 'fedora/x86_64/images/pxeboot/initrd.img'
bootloarder_args = ['--location=http://192.168.0.1/']
You can also omit the `--location' option and specify the full URL for
`kernel' and `ramdisk' directly, e.g.:
kernel = 'http://192.168.0.1/fedora/x86_64/images/pxeboot/vmlinuz'
ramdisk = 'http://192.168.0.1/fedora/x86_64/images/pxeboot/initrd.img'
If only `--location' is specified and `kernel' and `ramdisk' are not
specified, `xenpvnetboot' will search the following places for boot
images from the location::
('images/xen/vmlinuz', 'images/xen/initrd.img'), # Fedora <= 10 and OL = 5
('boot/i386/vmlinuz-xen', 'boot/i386/initrd-xen'), # openSUSE >= 10.2 and SLES >= 10
('boot/x86_64/vmlinuz-xen', 'boot/x86_64/initrd-xen'), # openSUSE >= 10.2 and SLES >= 10
('current/images/netboot/xen/vmlinuz', 'current/images/netboot/xen/initrd.gz'), # Debian
('images/pxeboot/vmlinuz', 'images/pxeboot/initrd.img'), # Fedora >=10 and OL >= 6
('isolinux/vmlinuz', 'isolinux/initrd.img'), # Fedora >= 10 and OL >= 6
`xenpvnetboot' requires python module `urlgrabber'
http://urlgrabber.baseurl.org/.

If user specifies a libdir it is used, if no libdir is specified
configure checks if $exec_prefix/lib64 is a directory and uses that,
if not lib is used.
$prefix is set by passing the command line option or by default when
calling AC_OUTPUT, but since AC_OUTPUT is called at the end, this is
not really helpful, so we have to set $exec_prefix manually to the
correct value, either $prefix if different than NONE or
$ac_default_prefix.

When a low memory threshold on the Xen heap is reached, we fire a
global dom0 virq. If someone's listening, they can free up some more
memory.
The low threshold is configurable via the command line token
'low_mem_virq_limit", and defaults to 64MiB. If the user specifies
zero via the command line, the virq is disabled.
We define a new virq VIRQ_ENOMEM. Potential listeners include
squeezed, xenballoond, or anything else that can be fired through
xencommons.
We error-check the low mem virq against initial available heap (after
dom0 allocation), to avoid firing immediately.
Virq issuing is controlled by a hysteresis algorithm: when memory dips
below a threshold, the virq is issued and the next virq will fire when
memory shrinks another order of magnitude. The virq will not fire
again in the current "band" until memory grows over the next higher
order of magnitude.

With changeset 24364:0964341efd65 an event channel based notification of
new responses in the ringbuffer is implemented. This makes the memevent
interface obsolete. Currently a call to p2m_mem_paging_resume() is
triggered twice by xenpaging, once per memevent and once per even
channel. In practice this double call does not lead to issues because
p2m_mem_paging_resume() processes only available events.
xenpaging used the event channel notification since the beginning, but
it was a no-op until changeset mentioned above. This change removes the
unneeded XENMEM_paging_op_resume functionality. Pagers are notified via
an event channel of new requests, and now they are required to notify
the hypervisor about their responses also with an event channel.

Add a parameter for the MMIO hole size when building a HVM domain.
This is useful for specifying a larger than normal MMIO hole to ensure
that no PCIe device's MMIO region overlaps with RAM in a guest's
physical address space. This is needed on certain systems with PCIe
switches with a broken ACS capability. On these systems, if a device
downstream of the switch attempts a DMA to a guest physical address
that overlaps with the MMIO region of another downstream device, then
the switch routes the transfer directly to the device and the read or
write never hits RAM.

consoles are not directly exposed to users of the library and there are no API
functions for manipluating them (only the console_exec function). Rather than
commit to a particular API now make the type internal.
When a user does come along it is much easier to add a completely new API
rather than to fix an existing broken one. It's easier to do this in a manner
which users of the library can cope with in a compatible way e.g. adding a new
API is easier to check for with ./configure.

This serves no purpose. It relates to the old 8M to "account for backend
allocations" which we used to add. This leaves a bit of unpopulated space in
the Pseudo-physical address space which can be used by backends when mapping
foreign memory. However 8M is not representative of that any more and modern
kernels do not operate in this way anyway.
I suspect an argument could be made for removing this from the libxl API
altogether but instead lets just set the overhead to 0.
