Connect to openvpn past enterprise firewall

The proper way is to do this :

1. Setup openvpn to use tcp instead of udp on any port (1194 is default)
2. Setup port forwarding to forward external 443 port to internal 1194 port.
3. If the web browser on client side is using a proxy setup the openvpn client to use the proxy server for connection.
4. Setup client to use tcp and port 443.

Then connect.

Thick-provisioned disk to thin, in ESX 4.1

On ESXi 4.1 Copying virtual machines machines using Veeam FastSCP (Free version), if the copied machine disk was thin-provisioned, the pasted machine will be thick, so one solution is use the following command

vmkfstools –i <srcDisk> -d thin <dstDisk>

but don't forget to edit the <dstDisk> to indicate <dstDisk-flat>

Recreating a missing virtual machine disk (VMDK) descriptor file

Powering on the virtual machine fails with the error: The file specified is not a virtual disk (15) or Recreating a missing virtual machine disk (VMDK) descriptor file follow links below from the VMware knowledge base

http://kb.vmware.com/kb/1002511

While following the steps, you may find the scsi controller is "lsisas1068" which is not supported as virtual controller in the command vmkfstools, so you can use "lsilogic" instead like I did with my Windows 2008 and it worked just fine.

HINT:
scsi0.virtualDev = "lsisas1068"
This new controller is only available with virtual hardware 7
it is a good choice for Windows 7 and 2008 R2
