I am running SLES10SP1 which has support for paravirtualization(it was added in SP1). My host is ESX3.5
I am a bit confused if I should enable the paravirtualization box on the sles guest. Will it increase performance? What are the downsides?
Thanks!
I'm not sure if VMI is included in SLES10 SP1. With an Ubuntu 7.04 VM, after enabling VMI, I get the following when executing "dmesg | grep vmi"
vmi: registering clock event vmi-timer. mult=10041167 shift=22
Booting paravirtualized kernel on vmi
When enabling VMI on a SLES10 SP1 VM, "dmesg | grep vmi" returns nothing

hmm...maybe I misread the sles10 info...maybe it was talking about vmi available with XEN?
Hello,
Paravirtualization within a Linux guest applies only to Xen. However, if you install VMware Tools you have a few VMware drivers available to you. vmxnet, balloon driver, etc. That is as close to paravirtualized you will get with VMware products.

This isn't completely true. ESX 3.5 includes VMI paravirtualization support for linux guests that support it. VMI support has been built into the latest linux kernels. I have tested and verified it with the latest versions of Ubuntu and OpenSuse. VMI support is supposed to be incorporated into the next releases of the enterprise linux versions as well.
