I know XenServer and I believe ESXi get installed on the bare metal. XenServer is a kind of stripped down Linux distribution of it's own. I know you *can* run Xen and KVM on openSUSE, CentOS and some other general distributions.<div><br></div><div>So is there a KVM "optimized" or KVM specific distribution if you're setting up a server just to run KVM, or if not, what distro do you recommend for KVM? Or would you just recommend whatever distro we're already familiar with (that supports KVM)?<br><br>Scott<br><hr id="zwchr"><div style="color:#000;font-weight:normal;font-style:normal;text-decoration:none;font-family:Helvetica,Arial,sans-serif;font-size:12pt;"><b>From: </b>"DJ-Pfulio" <DJPfulio@jdpfu.com><br><b>To: </b>"Atlanta Linux Enthusiasts" <ale@ale.org><br><b>Sent: </b>Friday, October 28, 2016 10:49:14 AM<br><b>Subject: </b>Re: [ale] Small Clusters for VMs<br><br>Thanks for responding.<br><br>Sheepdog is the storage backend.
