When you upgrade the kernel on a linux based host, you have to do a reboot for the system to actually start utilizing the new kernel. One thing you’ll notice, is that when you restart, your virtual machines, including the webaccess are unavailable and stopped responding. What do you do? Panic!!(?) No. You simply have to run a very easy command (the vmware config perl script) and follow the prompts. When in doubt, just hit enter all the way through.
sudo vmware-config.pl
Within a few minutes, your servers should be back up.
