Actually, deploying it on ESXi and on XenServer is both very easy. |
29 |
The difference is, XenServer has 2 options for the guests: |
30 |
1) Fully Virtualised |
31 |
2) Paravirtualised |
32 |
|
33 |
ESXi only supports the first. |
34 |
If you install all VMs using the first option, it is very simple. |
35 |
|
36 |
But, if you want maximum (as in, near native) performance, the 2nd option |
37 |
is definitely worth the extra effort. |

I use a Gentoo Dom0 (Xen Host) with several Gentoo VMs running on top of |
40 |
it. I only had to add a few options to the kernel configuration to get the |
41 |
VMs working. |
42 |
Similar effort to installing a Gentoo guest on ESXi, but on ESXi, I would |
43 |
need to add the VMWare tools to get the VMs to shutdown correctly when I |
44 |
need to shutdown the host. |
