(#2) Workaround to fix race condition around libvirt init.
This patch fixes the race condition caused when mutiple
threads try to start VMs at the same time. This patch
also fixes the issue of incorrect mem allocation for
VSSD property - emulator.
#2: included Edurdo's patch for make_space
took care of coding guidelines.

Libvirt-cim] [PATCH] [Draft] add ethernetport device type, testing result
by Wayne Xia
this patch also made ethernetport a bit different from networkport:
ethernetport would include the ports on the bridge/switch, not only the
ports on the VMs. The bridge/swtich is named with a prefix "VS_".
testing result:
A VM "test1" with 2 ports, is started, then:
wbemcli -nl ein

[Draft] add ethernetport device type, do you think this style is acceptable?
This patch is a draft for virtual LAN management. According to the DSP file
ethernetport class is needed, but currently we only have networkport class.
In this patch, additional information is added to net device representing the
cim class, because ethernetport is the subclass of networkport, and they should
share the same xml parsing procedure but show as different instances. To achieve
this, some functions are changed to add one more parameter stands for the cim
class it wants.
Also some association mapping is changed to add ethernetport.
