Well, I’m sure that there are many people that are running VMware Server 2 on CentOS 5. After all, it’s one of the major Host OSes that VMware recognizes. Popularity notwithstanding, there is a major bug that can bring your VM screamer to a hault.
CentOS 5.4 has a new glibc package that essentially breaks VMware Server’s hostd process. There are many posts out there regarding the issues, and various means of fixing them. However, I am just going to summarize info I’ve found out there on the net, and hopefully you should be able to follow very easily and get your VMs back up and running.
VMware Server 2 (hostd) crashes on CentOS 5 after upgrading to the latest releases of glibc and glibc-common
NOTE ON SOLUTIONS: There are two methods to solve this. The first requires downgrading the libraries system-wide. This should be fine if you only use the CentOS host as a VMware Server Host and nothing else. However, if you are in doubt whether your other applications, etc. on that host will run on a slightly older version of glibc, please use SOLUTION METHOD 2 as it will only affect VMware, and essentially tell VMware Server where to look for the correct libraries it needs.
