Hi All,
Can some on assist us in the following VM situation. We have an ESX 4.1i running on compaq server. as 4.1i only supports 1 cpu. we have acquired 4.0 and another cpu.

Now what we want is the abillity to back up existing VMS succesfully

Format our existing ESX server and install new esx 4 on that server and install 2 cpus and then restore our VMs on that.

I have come to know that i can not use vmotion as vsphere for 4.1 i DOES NOT support it :(..

looking forward to get solution for this.

"aspiremsp"...I'm not sure how you get that ESXi 4.1 only supports 1 CPU? If you see here: http://www.vmware.com/products/vsphere/buy/small_business_editions_comparison.html, you'll notice that it supports multiple processors (no processor limit).

And ESXi 4.1 does support vMotion...but more specifically, the "free" version (vSphere Hypervisor), doesn't.

But, if you want to move your VMs off your current host, you can download Veeam FastSCP for free (http://www.veeam.com/vmware-esxi-fastscp.html) or WinSCP (http://winscp.net/eng/download.php) and move your VMs to a temp storage location; install ESX or ESXi as you need; then move the VMs back using the same tool.

Another option to move your VMs, but I personally don't recommend it just because it's limited in where you can move your VMs to, is to use vCenter Converter Standalone:
https://www.vmware.com/tryvmware/?p=converter&ie=UTF-8&rlz=1T4GGLL_enUS371US371&q=vcenter%20converter
But, it is another option for you.

Thanks for that, I downloaded Veeam in the mean time and ready to use this. but i will also try winSCP as it has almost no over head compared to veeam.

also thanks for clarifying on esxi4.x.
but can you please also calrify that whether esxi4.1 is also FREE available.
the one which i have installed is Free one and i logged on to its console to see whether it was vm hypervisor or esxi4.0 and i could not find hypervisor any where.

in a nut shell currently i am running VMware ESXI 4.0.0, 171294. Is this vm hypervisor or actual esxi that can support more than 2 cpus ?

Sure...ESXi 4.1 (now called vSphere Hypervisor), is free. When you go to download it, after you log in and are at the actual download screen, you receive a license code. This needs to be entered on the host through the vSphere Client or your 'trial' will expire. It's a perpetual (never-ending) license, and you can use it on multiple ESXi hosts (999 to be exact), but it still needs entered or you will lose some basic functionality to your VMs (unable to power on if you power it off, as well as other things).

To see if you have ESX or ESXi, and what version, when you log on to the host with the vSphere Client, it will show you. For example, if you go to this link and look at the second screenshot (http://www.petri.co.il/managing-esxi4-with-vsphere-client.htm), above the 'Summary' tab, you see (it's hard to read though) that the poster is running ESXi 4.1 Build number xxxxxx.

Both ESX and ESXi are baremetal HOST hypervisors (not VM hypervisors). Either supports more than 2 CPUs. Are you referring to if they support more than 1 or 2 CPUs for a VM? You are allowed to allocate more than 1 CPU to a VM if you have more than 1 physical CPU on the host. Now, if you have 1 physical CPU socket, but it has multiple cores (dual, quad, etc.), you are also allowed to give a VM more than 1 vCPU.

Hope that helps.

Well, to use WinSCP, you actually need to enable SSH in the 'unsupport mode'. For Veeam, you don't but WinSCP you do. You can see how to enable SSH for the unsupport or tech support mode here:

Excellent, thankf for elaborating it. The reason i was assuming it only supports one processor was because of the screen shot ( please see attached) it mntions that "Licensed for 1 physical CPU"

Also i had done the license update as per you mentioned.

it also menitones the build number and version and i am trying to figure out  whether i am using vmhypervisor or HOST hypervisor ?

Also, Can you please tell me how do we access esx using winscp ? i.e. which protocol and ports.

Cheers,

1. That's correct...this host is licensed for 1 CPU because you have 1 physical CPU in your host. It has 4 cores, but only 1 socket...correct? So, what you're seeing is accurate. It would show differently if you have multiple physical socket CPUs.
2. ESX and ESXi are both baremetal hypervisors that run on a host/server. There is no such thing as a VM hypervisor. There is such thing as a Host OS-based hypervisor, though. Examples are VMware Server, VMware Workstation, Microsoft Virtual Server, Microsoft Virtual PC, etc.
3. WinSCP uses SSH protocol, TCP port 22 to access the host. Once you download/install WinSCP, you have to enable SSH on your ESXi host, which requires you to be at the actual console of the host. Use the link I provided to enable SSH on your host.
