I just found out a few weeks ago that XenServer 6.2 went Open Source. We are currently hosting virtual machines on the free ESXi version where I work. The VMs run fine, but we have none of the advanced (basic virtualization necessities) such as HA, host clustering, live migration, etc.
Instead of throwing out $15k for a VMware Essentials kit, I have been testing XenServer and XenCenter 6.2 in my virtual lab. I'm about ready to make the leap, but the longevity of XenServer remains bleak in my mind.
Do any of you have XenServer environments? Do you have any opinions about whether XenServer will be relevant and supported by third party vendors in the future?
