Zhigang Wang [Thu, 1 Mar 2012 18:54:37 +0000 (18:54 +0000)]
add new bootloader xenpvnetboot for pv guest
`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'

Global virq for low memory situations
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

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
