[bmishkania at ussd-prd-rdln01 xpra-2.2.3]$ xpra showconfig | grep -i ^xvfb
xvfb = 'xpra_Xdummy -noreset -novtswitch -nolisten tcp +extension GLX +extension RANDR +extension RENDER -auth $XAUTHORITY -logfile ${XPRA_LOG_DIR}/Xorg.${DISPLAY}.log -configdir ${XDG_RUNTIME_DIR}/xpra/xorg.conf.d/$PID -config /home/bmishkania/bin/localPython/etc/xpra/xorg.conf'
It seems like it is still trying to use Xdummy but I am not sure why. I tried next to install Xvfb as suggested:
yumdownloader xorg-x11-server-Xvfb
rpm2cpio ./xorg-x11-server-Xvfb-1.19.3-11.el7_4.1.x86_64.rpm | cpio -idmv
cp ./usr/bin/Xvfb ~/bin/ # copy Xvfb to directory that is in $PATH
rm -r ~/bin/xpra-2.2.3/
./setup.py --without-Xdummy install --home=/home/bmishkania/bin/xpra-2.2.3/
The build switches show:

But it doesn't seem to have helped:

This error message has now been improved:

Based on this message, I'm not convinced that you are actually using
xvfb. Double-check your configuration with:
xpra showconfig | grep -i ^xvfb
> I do not think Xvfb is installed on this system, even though Xorg is.
The xorg-x11-server-Xvfb package on CentOS / RHEL 7.x only contains one
binary file named "Xvfb". You can just unpack the RPM by hand and put
the binary in your $PATH. The dependencies should already be present if
you have /usr/bin/Xorg installed.

Yes, figure out why you get those tty errors when running xpra_Xdummy.
Regular CentOS 7.x systems can normally run it just fine.
