emellor@ewan af1b5637f4 Allow parallel 32- and 64-bit Xen installations. Move xc_save, xc_restore,
and xenconsole out of /usr/libexec/xen and into one of /usr/lib/xen/bin or
/usr/lib64/xen/bin.  Remove all the PATH hacking inside Xend, and rely upon
the PATH being set correctly from outside.  Added an auxbin module for
handling the hacky stuff.

Replace the few /usr/bin/python bang paths with /usr/bin/env python.

emellor@ewan d0c7f9b2ad This patch fixes an error in the xm create path when the
xc.domain_create call fails (eg, when ACM policy prevents creation of a
domain).  When xc.domain_create fails, dompath never gets set.

emellor@ewan dc988367d8 Rewritten XendLogging to not be a singleton class, and not have methods used
from nowhere at all.

Log to a temporary file if permission is denied to log to /var/log/xend.log,
as happens when you are not root.  Fixes bug #305.

Remove all the log-related garbage from XendRoot -- just about every module
was going straight to XendLogging.log already, so there was no need to have
XendRoot replicate this functionality.

Remove XendRoot.event_handler, which hasn't been in use since the EventServer
was removed.

emellor@ewan 9c04557e2d Remove code seeding RNG from /dev/urandom. The random module's default RNG is
already seeded from the clock, so this is unnecessary, non-portable, and
expensive.  This should improve start-up time of Xend.  Replace twisty maze of

kaf24@firebug.cl.cam.ac.uk c804adf4b6 Change how event channels are allocated and used by the control
tools. /dev/xen/evtchn is now used by daemons to connect to
remote domains: the advantage is that the local ports are garbage
collected automatically if the daemon dies. xen no longer
constructs end-to-end event-channel port pairs -- it allocates an
unbound port in new domU and writes that port to xenstore. It is
then picked up by teh appropriate daemon which does interdomain bind
via /dev/xen/evtchn.

emellor@ewan 0465a697d3 Rename all dying domains to be prefixed with Zombie. This allows a new domain
to be created with the same name, fixing the race condition inside XendDomain
that caused bug #278.

Move the state_set(TERMINATED) call onto the end of cleanupDomain rather than
destroyDomain, so that this flag is set when XendDomain cleans up a domain
that was killed without going through Xend.

Remove is_terminated, as this check is no longer necessary, since we are using
Zombie prefixes instead.

emellor@ewan a00e0c297c Fix the handling of VCPUs, specifically wrt the broken VCPU hotplugging, bug
#280.  The cpu/<id>/availability paths had moved into /vm, but that is not
easily accessible by the hotplugging driver, so I have created a /vm entry
called vcpu_avail, so that the setting migrates along with the domain, and
moved the cpu/<id> ones back to /local/domain.

Don't try and destroy the domain twice if it fails within construct.  This
wasn't harming anything, but there's no need.
