P2V for CentOS 4.7

I am trying to virtualize my CentOS 4.7 server into VMware. I am using an acronis linux boot disk to make a backup and then restore to a VM. When I boot the VM I get a kernel panic.

I am pretty sure that the problem is that CentOS 4.7 is not configured to use the correct SCSI driver which prevents it from finding the root drive which causes the kernel panic. I think I just need to use mkinitrd to compile a new kernel boot image with the VMware LSI SCSI driver.

The problem is that I am a linux novice and I need idiot proof instructions on how to do this. I was able to get the VM to boot if I put in a CentOS 5.2 install disc and upgrade, but then all my applications do not work, because they were compiled for CentOS 4.7. I also tried using a CentOs 4.8 install disc to do an upgrade, but it doesn't redetect my SCSI like the 5.2 install disc did.

Any help would be great.

The app is very easy to use, you pick the source machine or image and then pick the destination (ESX/ESXi host, VMware Workstation etc)

I forget which allows you to do remote machines, but it will tell you when you install it if you need server, there is a little info window that pops up.

So I should just start the install on my production CentOS box and see what happens?

Unless you want to test it on a quick VM first.

It is asking if I want to install client and/or server. The default is yes to both. use defaults?

It is installing now. I accepted all defaults accept for tcp port numbers which would conflict with the web app on the server.

To convert the local machine I think you only need the client.

Are you running it from X Windows or a command line only boot?

putty ssh session.

Anyways, i skipped that and ran the converter on my windows pc and started the P2v task to one of our ESX boxes. so far so good.

I am hoping to copy the vmdk file from this new VM to use with VMware server 2.x. That should work right?

Yes, it will work with all the current versions of VMware and quite a few older ones.

14 % done now. You may not here fro me until tomorrow. I will let you know how it goes. I assume the Converter will install all the needed SCSI drivers for me.

I used vmware converter on my windows pc to connect to the vmware converter client on my linux box, then transfered to my ESX host, installed vmware tools, them shutdown VM and moved the vmdk file to my other server running VMware server 2.x and swapped in the new vmdk file. Worked like a charm.
