We are using VMware (with VMotion) to provide HA for a cluster of Oracle databases and application servers running on Linux and it works very well, but Paul is right that it doesn't provide automatic failover. This environment can tolerate the few minutes of downtime that would be required to restart the virtual host on another physical host and then have users reconnect.

I just skimmed the document Paul linked to below and apparently they offer a higher level of HA called "VMWare Fault Tolerance" that will provide faster, automated failover functionality but I don't have any experience with that.

Regards,
Brandon

By itself, vMotion does not provide failover. www.vmware.com/pdf/vsphere4/r41/vsp_41_availability.pdf
