eb7be6a606 Add a new 'virsh qemu-attach' command.
This command allows libvirt to attach to an existing QEMU
instance.

 $ qemu-kvm -cdrom ~/demo.iso \
     -monitor unix:/tmp/demo,server,nowait \
     -name foo \
     -uuid cece4f9f-dff0-575d-0e8e-01fe380f12ea  &
 $ QEMUPID=$!
 $ virsh qemu-attach $QEMUPID

4403646001 Define remote wire protocol & impls for virDomainQemuAttach
This tweaks the RPC generator to cope with some naming
conventions used for the QEMU specific APIs

* daemon/remote.c: Server side dispatcher
* src/remote/remote_driver.c: Client side dispatcher
* src/remote/qemu_protocol.x: Wire protocol definition
* src/rpc/gendispatch.pl: Use '$structprefix' in method
  names, fix QEMU flags and fix dispatcher method names

639f841346 Define a QEMU specific API to attach to a running QEMU process
Introduce a new API in libvirt-qemu.so

 virDomainPtr virDomainQemuAttach(virConnectPtr domain,
                                  unsigned long long pid,
                                  unsigned int flags);

This allows libvirtd to attach to an existing, externally
launched QEMU process. This is useful for QEMU developers who
prefer to launch QEMU themselves for debugging/devel reasons,
but still want the benefit of libvirt based tools like
virt-top, virt-viewer, etc

df94811f71 build: avoid requiring -lm
log2() is heavy when ffs() can do the same thing.  But ffs()
requires gnulib support for mingw.

This patch solves this linker error on Fedora 14.

/usr/bin/ld: libvirt_lxc-domain_conf.o: undefined reference to symbol 'log2@@GLIBC_2.2.5'
/usr/bin/ld: note: 'log2@@GLIBC_2.2.5' is defined in DSO /lib64/libm.so.6 so try adding it to the linker command line
/lib64/libm.so.6: could not read symbols: Invalid operation
collect2: ld returned 1 exit status

* .gnulib: Update to latest, for ffs.
* bootstrap.conf (gnulib_modules): Import ffs.
* src/conf/domain_conf.c (virDomainDefParseXML): Use ffs instead
of log2.

aa14709a47 Add domain type checking
The drivers were accepting domain configs without checking if those
were actually meant for them. For example the LXC driver happily
accepts configs with type QEMU.

Add a check for the expected domain types to the virDomainDefParse*
functions.

eb3143154e Do not drop kernel cmdline for xen pv domains
Kernel cmdline args can be passed to xen pv domains even when a
bootloader is specified.  The current config-to-sxpr mapping
ignores cmdline when bootloader is present.

Since the xend sub-driver is used with many xen toolstack versions,
this patch takes conservative approach of adding an else block to
existing !def->os.bootloader, and only appends sxpr if def->os.cmdline
is non-NULL.

8a8b45b889 kill vm if saving config failed in v3 protocol
If virDomainSaveConfig() failed, we will return NULL to source,
and the vm is still available to restart during confirm() step in
v3 protocol. So we should kill it off in qemuMigrationFinish().

In v2 protocol, we should not set vm to NULL, because we hold
a reference of vm and should unrefernce it.

b1c9bf27cb tests: Fix compressed test output padding logic
The current logic tries to count from 1 to 40 and ignores paddings

like here for counter value 159

      ........................................ 80
      ........................................ 120
      ....................................... 159 OK
PASS: virsh-all

Also seq isn't portable. Therefore, calculate the correct padding
length directly and use printf to output it at once.

3cfdc57b85 Fix sending of reply to final RPC message
The dispatch for the CLOSE RPC call was invoking the method
virNetServerClientClose(). This caused the client connection
to be immediately terminated. This meant the reply to the
final RPC message was never sent. Prior to the RPC rewrite
we merely flagged the connection for closing, and actually
closed it when the next RPC call dispatch had completed.

afe8839f01 Fix leak of remote driver if final 'CLOSE' RPC call fails
When closing a remote connection we issue a (fairly pointless)
'CLOSE' RPC call to the daemon. If this fails we skip all the
cleanup of private data, but the virConnectPtr object still
gets released as normal. This causes a memory leak. Since the
CLOSE RPC call is pretty pointless, just carry on freeing the
remote driver if it fails.

2c85644b0b Fix release of outgoing stream confirmation/abort message
When sending back the final OK or ERROR message on completion
of a stream, we were not decrementing the 'nrequests' tracker
on the client. With the default requests limit of '5', this
meant once a client had created 5 streams, they are unable to
process any further RPC calls.  There was also a bug when
handling an error from decoding a message length header, which
meant a client connection would not immediately be closed.

2f4d2496a8 util: Don't try to fchown files opened as non-root
When virFileOpenAs is called with VIR_FILE_OPEN_AS_UID flag and uid/gid
different from root/root while libvirtd is running as root, we fork a
new child, change its effective UID/GID to uid/gid and run
virFileOpenAsNoFork. It doesn't make any sense to fchown() the opened
file in this case since we already know that uid/gid can access the file
when open succeeds and one of the following situations may happen:

- the file is already owned by uid/gid and we skip fchown even before
  this patch
- the file is owned by uid but not gid because it was created in a
  directory with SETGID set, in which case it is desirable not to change
  the group
- the file may be owned by a completely different user and/or group
  because it was created on a root-squashed or even all-squashed NFS
  filesystem, in which case fchown would most likely fail anyway

18d561c7a4 public API: prefer unsigned int for flags
Most APIs use 'unsigned int flags'; but a few stragglers were using
a signed value.  In particular, the vir*GetXMLDesc APIs were
split-brain, with inconsistent choice of types.  Although it is
an API break to use 'int' instead of 'unsigned int', it is ABI
compatible (pre-compiled apps will have no difference in behavior),
and generally apps can be recompiled without any issue (only rare
apps that compiled with extremely high warning levels, or which
pass libvirt API around as typed function pointers, would have to
make any code changes to deal with the change).

The migrate APIs use 'unsigned long flags', which can't be changed,
due to ABI constraints.

This patch intentionally touches only the public API, to prove the
claim that most existing code (including driver callbacks and virsh)
still compiles just fine in spite of the type change.

* include/libvirt/libvirt.h.in (virConnectOpenAuth)
(virDomainCoreDump, virDomainGetXMLDesc, virNetworkGetXMLDesc)
(virNWFilterGetXMLDesc): Use unsigned int for flags.
(virDomainHasCurrentSnapshot): Use consistent spelling.
* src/libvirt.c (virConnectOpenAuth, virDomainCoreDump)
(virDomainGetXMLDesc, virNetworkGetXMLDesc)
(virNWFilterGetXMLDesc, do_open): Update accordingly.

313ac7fd39 maint: print flags in hex during debug
Debugging decimal flags is a pain.

* src/libvirt.c: Always print flags in hex.

085d241531 virsh: make destroy sound less scary
Destroy has a rather negative English connotation.  Try to reduce
the impact, so newbies aren't as scared to use it.

* tools/virsh.c: Tweak all destroy documentation.
* tools/virsh.pod: Likewise.

c2dda6ebb3 build: fix virBufferVasprintf on mingw
Gnulib documents that mingw vsnprintf is broken (it returns -1
on out-of-space, instead of the count of what would have been
printed); but while we were using the snprintf wrapper, we had
not yet been using the vsnprintf wrapper.

Meanwhile, mingw (but not mingw64) has a replacement snprintf
that fixes return values, but still lacks %1$s support; so in
that case, gnulib didn't replace snprintf, but libintl then
went ahead and installed a version that supported %1$s but not
return values.  Gnulib has since been fixed to guarantee that
the snprintf module will always guarantee the constraints needed
by libintl.

Also, we want to guarantee that strdup sets errno on failure.

* .gnulib: Update to latest, for vsnprintf fix.
* bootstrap.conf (gnulib_modules): Add vsnprintf, strdup-posix.
