* qemud/conf.[ch]: significantly re-factor qemudLoadConfigXML()
so that "parse the XML", "assign the def to a VM" and
"save the XML" operations are in separate functions.
Add qemudRemoveInactiveVM() and qemudRemoveInactiveNetwork().
Report errors when loading config files at startup. Check
that a domain/network's name matches the config filename.
* qemud/driver.c: update the Create() and Define() functions
to explicitly parse/assign/save. Also, fix bug where if
Create() failed, we would free the VM without removing it
from the inactive list.
* qemud/qemud.c: use qemudRemoveInactiveVM/Network()
* qemud/driver.[ch], qemud/dispatch.c: fix the fact that
qemudDispatchDomainStart() doesn't report an error if the uuid
lookup fails and also move the uuid lookup into the driver
so that it matches the way we do Destroy().
* qemud/conf.c, qemud/driver.c, qemud/internal.h,
qemud/qemud.c: Merge the ->activevms and ->inactivevms
into a single ->vms list in order to make things
easier to manage. Likewise for networks. Also add
qemudIsActiveVM() and qemudIsActiveNetwork() inline
functions.
Fix a few leaks
* qemud/qemud.c: qemudCleanup(): free the socket
structures
* qemud/conf.c: fix various leaks in the xml parsing
* qemud/iptables.c: fix a typo causing a leak
* qemud/qemud.c: clean up qemudInitialize() and qemudListen()
so as to coalesce the two "system vs. user" code paths and
fix up some problems noticed by dan.
* qemud/qemud.c, qemud/dispatch.c, qemud/internal.h
qemud/conf.c, qemud/driver.c, configure.in: add a
qemudLog() function which uses syslog() if we're in daemon
mode, doesn't output INFO/DEBUG messages unless the
verbose flag is set and doesn't output DEBUG messages
unless compiled with --enable-debug. Also, make a first
pass through fatal errors and add error messages for them.
* qemud/internal.h, qemud/qemud.c: improve signal handling
and handle SIGHUP by shutting down all guests and networks
and re-loading configs, and handle SIGINT and SIGTERM
by shutting down cleanly.
* qemud/qemud.c, qemud/bridge.c, qemud/iptables.c: fix
our FD_CLOEXEC usage so that all fds which should be
closed on exec are marked as such and that we leave
exec() to do the actual closing.
* qemud/iptables.[ch]: add code for managing iptables
rules.
* qemud/Makefile.am: add iptables.[ch].
* qemud/qemud.c: add and remove iptables rules as
appropriate.
* qemud/conf.c: when starting a guess, add a rule
allowing it to forward packets across the networks
bridge.
* qemud/internal.h: add iptables context ptr
* configure.in: add --with-iptables-dir and
--with-iptables-prefix to allow us to put our rules
in a chain with the given prefix and save the rules
in files in the given dir so as to integrate with
the proposed "service iptables restart" solution
in:
https://bugzilla.redhat.com/227011
* include/libvirt/libvirt.h.in, src/libvirt.c: add
virNetworkGetBridgeName() to allow finding out what
bridge to connect to in order to join a network.
* src/driver.h: add networkGetBridgeName() to vtable.
* qemud/protocol.h: add the request and reply to
the qemud protocol.
* qemud/dispatch.c, qemud/driver.[ch]: handle them
here.
* src/qemu_internal.c: implement GetBridgeName()
in the qemu driver.
* src/libvirt_sym.version: add new symbol.
* src/xend_internal.c, src/xm_internal.c: pass the
connection to virDomainParseXMLDesc()
* src/xml.[ch]: make virDomainParseXMLDesc accept
a virConnectPtr so that we can use it later to
lookup the bridge associated with a network
* tests/xml2sexprtest.c: just pass NULL here, it's
safe
* qemud/conf.c: add support for connecting a qemu
guest to a bridge using a tap device in order to
connect it to a virtual network.
* qemud/internal.h: add <interface type="network">
config and track tapfds so as to not close them
on exec.
* qemud/qemud.c: don't close tapfds on exec and
disconnect the iface when the guest shuts down.
