Proxmox or XenServer?
Right now I have Proxmox installed in my Online.net 1115 for personal uses and I think it's decent. I like that I can manage it via the web interface and that it's debian based.
The reason I am planning to go full virtualization is because I'm sick of configuring everything on bare metal over and over whenever I need something different and that I think a KVM/XEN vm would serve me better.
Right now it's installed in one server and I'm thinking of installing it to my Online.net 1215 server. So that I can move VPSes between servers in case of error etc. Or backup one machine to another.
I have been tinkering around with Proxmox for a week or so. Before that I tried installing ESXi and found that it's a tad too complex to setup and access NAT VM's compared to Proxmox.
Right now I can easily have IPv6 only VMs, NAT VMs, NAT + IPv6 VMs and if I buy failover IP's I have VMs with their own IP. I think I figured out most of it's uses already. I don't think I will need much support for it other than Google results.
There's also one other server in question, XENServer. I haven't tried it.
I was wondering, is it worth switching over?
Is it somehow more secure?
Is it easier/more complex to manage?
Is cloning, making templates, networking, automating, managing better or worse in XenServer?
How hard is it to setup HA on both? Do I need special hardware?
What can I do with that that can't be done with Proxmox?
Since many people here are in hosting business and that they know both servers or at least they're like-minded, I'ld like to get your opinion before I try installing the other one. Or any other good, free ones that can replace Proxmox. I should also add that I am new to virtualization stuff.
And please, only those who used or have the knowledge for both of them comment on it.
