Being able to grab your existing desktop remotely with all open windows and long-running programs intact is a big plus, though - and you get that for free with NX or x2go. Can you connect remotely to your VM host some other way if you aren't at the special desktop?
How much different is that from VNC? Just curious.
VNC just does a basic bit-copy of the screen for the remote side so it is not particularly efficient, although it might be better if you are mirroring a real console instead of running a virtual session set up by vncserver. NX/x2go have a full proxy/stub X server and client at both ends with tunable caching/compressiion on the remote side.so things like font rendering and block moves for scrolling are much faster. X2go also can map audio/drives/printers if you want.
Both are packaged and fairly easy to try on CentOS 6. On 7, only x2go is available and it has a problem with the 3d requirement of Gnome3 so you have to use KDE or install MATE from EPEL.
