VMWare Issue "Operation Failed Since Another Task Is In Progress"

You get this issue qhen a Vmachine is frozen. It's a snapshot issue. To fix this without rebooting the ESX server, you just have to kill the VM process via command line.

• Login with SSH into the host running the frozen vmachine
• The command
  cat /proc/vmware/vm/*/names
  shows you the list of the running VM's on the host. Write down the vmid of the frozen vm
• The command
  less -S /proc/vmware/vm/vmid_frozen_vm/cpu/status 
  shows you some stats about the vm. Scroll to the right with the right arrow key to get the vm id group (i.e. vm.1760). Write down the number after "vm."
  
• The command
  /usr/lib/vmware/bin/vmkload_app -k 9 vm_id_group
  unlock the vm and power off it. In a while you'll be able to run it again.

How to install VNC server on Fedora

to install it:
yum install vnc-server

as root edit /etc/sysconfig/vncservers
VNCSERVERS="3:yourusername"
VNCSERVERARGS[3]="-geometry 1024x768 -depth 16"

with this configuration, vnc server will listen on port 5903 for user yourusername
to setup a multiple vnc server:
VNCSERVERS="1:username1 2:username2 3:username3"
VNCSERVERARGS[1]="-geometry 1024x768 -depth 16"
VNCSERVERARGS[2]="-geometry 800x600 -depth 8"
VNCSERVERARGS[3]="-geometry 800x600 -depth 16"

in this case vncserver ill listen on ports 5901 (for username1), 5902 (for username2) and 5903 (for username3).

to set the password, login as user, then:
vncpasswd

start the service as root with /etc/init.d/vncserver start

as user edit /home/yourusername/.vnc/xstartup
and uncomment the following lines:
unset SESSION_MANAGER
exec /etc/X11/xinit/xinitrc

and restart the service as root: /etc/init.d/vncserver restart

now you'll be able to connect from a vnc client at your_vnc_server_hostname:590x
