This patch adds a 'domid' field to libxl_domain_create_info and then
modifies libxl__domain_make() to have Xen use that value if it is valid.
If the domid value is invalid then Xen will choose the domid, as before,
unless the value is the new special RANDOM_DOMID value added to the API.
This value
Currently both xl and libxl have internal definitions of INVALID_DOMID
which happen to be identical. However, for the purposes of describing the
behaviour of libxl_domain_create_new/restore() it is useful to have a
specified invalid value for a domain id.
This patch therefore moves the libxl defin
This function implements a file-based lock with a file name generated
from a domid.
This patch splits it into two, generalising the core of the locking code
into a new libxl__lock_file() function which operates on a specified file,
leaving just the file name generation in libxl__domain_userdata_lo
This patch adds a new global 'domid_policy' configuration option to decide
how domain id values are allocated for new domains. It may be set to one of
two values:
"xen", the default value, will cause an invalid domid value to be passed
to do_domain_create() preserving the existing behaviour of hav
A domid is considered recent if the domain it represents was destroyed
less than a specified number of seconds ago. For debugging and/or testing
purposes the number can be set using the environment variable
LIBXL_DOMID_REUSE_TIMEOUT. If the variable does not exist then a default
value of 60s is use
The 'soft reset' code path in libxl__domain_make() is currently taken if a
valid domid is passed into the function. A subsequent patch will enable
higher levels of the toolstack to determine the domid of newly created or
restored domains and therefore this criteria for choosing 'soft reset'
will no
This patch adds a '-D' command line option to save and migrate to allow
the domain id to be incorporated into the saved domain configuration and
hence be preserved.
NOTE: Logically it may seem as though preservation of domid should be
dealt with by libxl, but the libxl migration stream has n

libxl: add definition of INVALID_DOMID to the API

Xenstore write limiting should not be applied to dom0. Unfortunately
write limiting is disabled only for connections via sockets. When
running in a stubdom Xenstore will apply write limiting to dom0, too.
Change that by testing for the domain to be privileged as well.

There are several places in xenstore-stubdom where newlines at the end
of messages on the console are missing. Add them.
