Nothing but vnet uses libxutil -- move it there.
Makefile, xc.c, setup.py, configure, configure.in, Makefile.in:
This doesn't use libxutil.
Makefile, Makefile.vnet, Rules.mk:
Move libxutil into vnet since it's only used there.
Many files:
mvdir
Implement the parts of vm save which need interaction with xend
as part of xend, instead of using xfrd.
Execute xc_linux_save in a seperate process so that it can't
crash xend. Also handle errors passed from xc_linux_save.
xen_domain.c:
Disable save in xfrd.
xc_save.c:
new file
Makefile:
Add xc_save.
XendDomainInfo.py:
Add suspended state and threading Condition with notification, allowing
easy waiting for state changes.
XendDomain.py:
Implement the parts of vm save which need interaction with xend
as part of xend, instead of using xfrd. Set state to "suspended"
when detecting a suspended domain.
Fix reading output from subprocesses.
Fix ValueError in xen_domain().
xc.c:
Remove python binding for xc_linux_save.
xc_linux_save.c:
Implement the parts of vm save which need interaction with xend
as part of xend, instead of using xfrd. Also run xc_linux_save
in a seperate process.
xc_linux_restore.c:
Flush output so that xend picks it up timely.
Also disable debug output again.
xc.h:
Update xc_linux_save prototype and fix comments for xc_linux_{save,restore}.
ignore:
Add tools/xcutils/xc_save.
xpopen.py:
Exit with 127 if exec fails.

Execute xc_linux_restore in a seperate process so that it can't
crash xend. Also handle errors passed from xc_linux_restore and
log info messages from xc_linux_restore.
XendDomain.py:
Popen xc_restore instead of calling xc_linux_restore directly.
xc.c:
Add pyxc_handle exporting the file descriptor to the control interface.
Remove xc_linux_restore -- replaced by popen of xc_restore directly
from python.
xc_linux_restore.c:
Enable debug output.
xpopen.py:
Add xpopen functionality:
Optionally exclude a list of file descriptors from being closed, allowing
access to those file descriptors from the command.
Remove unused parts.
xpopen.py, Makefile, xc_restore.c:
new file
Makefile:
Add xcutils subdir.
ignore:
Add tools/xcutils/xc_restore.
