Still waiting for them to produce a native Linux VMware client
As the title says...
VMware have ignored all requests (there has been a thread running for 2 years on their forums) for a version of Virtual Center or the Virtual Infrastructure client that will run natively on Linux.
So if you are an enterprise with only Linux servers and Linux virtual machines and want to use VMware ESX, you have to go and buy, manage, support, patch and secure a Windows server just to manage ESX.
So much for "joining the Linux club".
