<p>I'm considering moving a number of small client sites to an unmanaged VPS hosting provider. I haven't decided which one yet, but my understanding is that they'll give me a base OS install (I'd prefer Debian or Ubuntu), an IP address, a root account, SSH, and that's about it.</p>

<p>Ideally, I would like to create a complete VM image of my configured setup and just ship those bits to the provider. Has anyone had any experience with this? I've seen <a href="http://www.codinghorror.com/blog/archives/000984.html" rel="nofollow noreferrer">Jeff talk about something like this in Coding Horror</a>. But I'm not sure if his experience is typical. I suppose it also depends on the type of VM server used by the host.</p>

<p>Also, do such hosts provide reverse-DNS? That's kinda useful for sites that send out e-mails. I know GMail tends to bounce anything originating from a server without it.</p>

<p>Finally, I'd probably need multiple IP addresses as at least a couple of the sites have SSL protection which doesn't work with name-based virtual hosts. Has anyone run into trouble with multiple IPs through VPS? I wouldn't think so, but I've heard whisperings to the contrary.</p>
