I still very much prefer VMWare (free or commercial depending on needs). Easy to hire staff that know it, easy to integrate with monitoring etc and depending on what you need it's not that bad pricewise IMHO
For my personal lab/dev stuff I run VMWare - at $$$job we run various systems but on Linux systems it's primarily Proxmox and Windows it's HyperV ... several companies I deal with are Xen across the board (which is by far the largest sets of deployments out there). I would run Xen but I just never got around to knowing it really well like I do VMWare ... -----Original Message----- From: Af [mailto:[email protected]] On Behalf Of Matt Sent: Friday, November 13, 2015 5:29 PM To: [email protected] Subject: Re: [AFMUG] Proxmox virtualization > The gains are insignificant with an openvz jail environment compared > to a paravirtualized (PV, not HVM) Xen environment.

I really like how light weight Openvz and LXC are. I can run my DNS server and Speedtest server as separate containers and they hardly use any resources at all. Works very well with small light weight servers like that. Seems like whatever memory you assign a KVM on other hand is gone even when its sitting twiddling its thumbs. Plus containers have very little performance penalty regarding CPU or disk I/O. I really like the ZFS file system that Proxmox 4 has switched too. Built in mirroring etc. but takes some figuring out. I am having issues with new LXC containers and centos 7 though. You have to do a number of tweaks to get around systemd, apparmor and LXC working together. I hate having to do tweaks.
