とりあえず使ってみた感想としては、遊びで使う分には十分に動く。
正直それ以上のコメントはしようがないなぁ。

β版だからしょうがないけど、俺が想定していた使い方（ゲストOSをテストサーバとして使う）は、ちょっとまだ難しいようです。

特に

Host-to-guest networking might not work in Bridged mode.
When the physical host ethernet adapter that VMware Fusion bridges to (usually “en0″) supports hardware TCP and UDP checksum offload, any TCP or UDP communication betwen the host and the guest will fail when the guest is configured to use a bridged network adapter.

If you need communication between the Mac OS X host and the guest, you can either set up port forwarding by editing /Libraries/Application Support/VMware Fusion/nat.conf and connect to the forwarded port on the Mac OS host (for host-to-guest communication), or use the real IP address of the host (for example, associated with “en0″) from the guest (for guest-to-host communication).

The host-only networking option is not implemented for this beta release.
For this beta release, only the NAT and bridged networking options are implemented.

Bridged networking does not work on hosts with a wireless Ethernet connection.
For this beta release, bridged networking works only for hosts with a wired Ethernet connection. Work is in progress on this problem.

のあたりは致命的ですね。

とりあえず、この辺の設定をすれば動くのかもしれない？が割とめんどくさそうなので萎えです。

とりあえずWindowsでVMWareを使っているのでfusionの公式版がでるまでのつなぎとして、Parallelsを買うか、他のLinux関連の仮想方法を考えてみます。

やっぱりOSの違うものを使おうとすると乗り換えコストかかるもんだなぁ。
