AFAIK Parallels is a fully virtualized hypervisor that requires no
hardware acceleration (maybe it does for OS X though...).

They are aimed to be ESX equivalents, but I think their user interfaces
need a little work, and I prefer the management software to be hosted
on the server instead of separate Java GUI apps.
At $500/socket they are 1/6th the cost of ESX server.

You can download 30 day trials of either and give them a whirl.
XenEnterprise is CentOS 4.4 with Xen 3.0.4 fully Xen Source patched,
which after trying out OSS 3.0.4 realized that it can take a whole
company to patch it to working condition.
Virtual Iron runs rPath + Xen 3.0.2 plus a whole slew of custom
additions like HVM save/restore/migration. Virtual Iron only does
HVM though, they have done-away with PV and the rPath is fully
embedded so no remote OS access, while with XenEnterprise you can
run CentOS as if you had installed it yourself.
