Per the documentation, is_selinux_enabled() returns -1 on error.
Account for this. Previously when -1 was being returned the condition
would still be true. I was noticing this because on my system that has
selinux disabled I was getting this in the libvirt.log every 5
seconds:
error : virIdentityGetSystem:173 : Unable to lookup SELinux process context: Invalid argument
With this patch applied, I no longer get these messages every 5
seconds. I am submitting this in case its deemed useful for inclusion.
Anyone have any comments on this change? This is a patch off current
master.

New functionalities:
- connectGetMaxVcpus - on bhyve hardcode this value to 16
- nodeGetFreeMemory - do not use physmem_get on FreeBSD, since
it might get wrong value on systems with
more than 100GB of RAM
- nodeGetCPUMap - wrapper only for mapping function, currently not
supported by FreeBSD
- nodeSet/GetMemoryParameters - wrapper only for future improvements,
currently not supported by FreeBSD
The virSocketAddrMask method did not initialize all fields
in the sockaddr_in6 struct. In paticular the 'sin6_scope_id'
field could contain random garbage, which would in turn
affect the result of any later virSocketAddrFormat calls.
This led to ip6tables rules in the FORWARD chain which
matched on random garbage sin6_scope_id. Fortunately these
were ACCEPT rules, so the impact was merely that desired
traffic was blocked, rather than undesired traffic allowed.

Valgrind reported leaking of maxCpus and arch strings from
virXPathString, as well as the leak of the machineMaxCpus array.
Don't use 'str' for the strings we don't want to free, to allow
freeing of 'str' in the cleanup label and free machineMaxCpus
in virCapsReset too.

Currently, we use pthread_sigmask(SIG_BLOCK, ...) prior to calling
poll(). This is okay, as we don't want poll() to be interrupted.
However, then - immediately as we fall out from the poll() - we try to
restore the original sigmask - again using SIG_BLOCK. But as the man
page says, SIG_BLOCK adds signals to the signal mask:
SIG_BLOCK
The set of blocked signals is the union of the current set and the set argument.
Therefore, when restoring the original mask, we need to completely
overwrite the one we set earlier and hence we should be using:
SIG_SETMASK
The set of blocked signals is set to the argument set.

Problem is, since 20745748 we do both, parse <alias/> elements from
XML files and call qemuAssignDeviceAliases(). While generating runtime
info for domain at runtime is just fine in the test, we can parse just
inactive XML and remove all <alias/>-es from the XML files.

libxl uses the libxl_vnc_info and libxl_sdl_info fields from the
hvm union in libxl_domain_build_info struct when generating QEMU
args for VNC or SDL. These fields were left unset by the libxl
driver, causing libxl to ignore any user settings. E.g. with
<graphics type='vnc' port='5950'/>
port would be ignored and QEMU would instead be invoked with
-vnc 127.0.0.1:0,to=99
Unlike the libxl_domain_config struct, the libxl_domain_build_info
contains only a single libxl_vnc_info and libxl_sdl_info, so
populate these fields from the first vfb in
libxl_domain_config->vfbs.

Emacs is fairly good about navigating across function and scope
boundaries, provided that the code has balanced {}. The vbox
code, however, violated that premise, by splitting 'if () {'
across several #ifdef branches, but sharing the '} else {...}'
outside of the branches. The extra lines of code is worth my
sanity, in a function that is already a horrendous 1100+ lines
long.
