Problem: A Parallels VM (either 9 or 10) has upgraded itself to CentOS 6.6, then the VM won't start the X Window system --- instead it stops during the boot sequence, when the progress bar across the bottom reaches CentOS 6.6 at bottom right. The bar goes complete white across the bottom, then dims to a gray color, and nothing happens further... the VM appears dead to the world.
Fix: Go to the Parallels Devices menu, Keyboard, then select Control-Alt-F2. This will kill off the hung X server, giving you a console login prompt. Log in, then go super-user. Change directory(cd) to /usr/lib/parallels-tools then run ./install Select the option to Upgrade. Allow the installer to download additional components etc until it completes. Allow the VM to reboot, and it will come up to the X server successfully. Pat yourself on the back, for you are a Linux wizard!
You may still need to update your Parallels tools to the latest version --- the procedure above reinstalled the existing version, which may be out of date. The normal Parallels tools update process should work without incident at this point.
Additional info: when the X window is killed, I tried starting X via xinit. This produced a bunch of log information that showed that the parallels video driver was out of date:
[ 27.406] (II) LoadModule: "prlvideo"
[ 27.407] (II) Loading /usr/lib64/xorg/modules/drivers/prlvideo_drv.so
[ 27.407] (II) Module prlvideo: vendor="Parallels Inc."
[ 27.407] compiled for 1.13.0, module version = 2.0.0
[ 27.407] Module class: X.Org Video Driver
[ 27.407] ABI class: X.Org Video Driver, version 13.0
[ 27.407] (EE) module ABI major version (13) doesn't match the server's version (15)
I couldn't access the parallels ISO from the zombie VM, but found the existing version (based on another thread)
I'm not sure if this is fixable, but THIS fix needs to be very very visible in Parallels support.
