emellor@ewan [Tue, 4 Oct 2005 10:14:50 +0000 (11:14 +0100)]
Fix localhost live migration.  We were overvigorously wiping out the store
entries when a domain closed and on save, which meant that the /vm entries
disappeared when a localhost migration occurred.  XendCheckpoint has had extra
exception handling and logging added.  It also now calls back through
XendDomain.restore_,which has the correct locking semantics to prevent race
conditions during migration.

Added assertions to XendCheckpoint to ensure that the channels are set after
XendDomainInfo.restore.  I don't see why they would not be, and the old code
meant that in the case that they were not, IntroduceDomain would not be called
on the new domain, breaking Xend restart.

relocate calls through XendDomain.domain_restore_fd rather than directly to
XendCheckpoint to isolate XendCheckpoint from the rest of the world, and to
allow XendDomain to pass itself into XendCheckpoint for a callback.

Simplify the XendCheckpoint / XendDomainInfo interlock, giving only two
states, OK and TERMINATED.  If XendCheckpoint asks for a suspend, but sees a
shutdown, it is valid for it to proceed -- either way the domain has stopped.
Higher level tools may wish to disallow this, but at the very least, there is
no sense in waiting for a suspend that will never come.

Move XendDomainInfo.{create,recreate,parseConfig} to the top level of the
domain.  This allows us to refer to them using an import statement, rather than
a from .. import.  This is a step towards getting rid of the xroot hack.  All
other references to XendDomainInfo methods need to be doubly qualified (once
for the module, once for the class).

Remove XendDomainDict, replacing it with a simple dictionary, folding the
get_by_name method into XendDomain.

Replace XendDomain.refresh_lock with a domains_lock which goes around any
reference to XendDomain.domains or anything that will create or destroy a
domain.  This serialises most accesses through XendDomain, ensuring that we will
not return stale state when racing against the watches fired in separate
threads.  This should have fixed bugs #270 and #234.

Added a number of domain_get_xyz methods.  Those named xyz_nr are to allow
components internal to XendDomain (XendDomainInfo, XendCheckpoint) to call back
into XendDomain without triggering further calls to XendDomain.refresh.  The
other methods simply make it clear which fallback behaviour is expected.

Replace XendDomainInfo.domain_exists with XendDomainInfo.domain_by_name; the
internals of this method needed to change to match those changes above, and it
has been a misnomer for some time.
