We moved all VPS servers from a proxmox 4 node to solusvm due to load and many LXC app apparmour and issues for cpanel servers. Load was our major issue.
I then decided seeing as its december to try proxmox 3.4 again just because I loved it so much and we never had issues before when using it before the upgrades this year and moved them all over there. I already converted them to openvz from LXC when I moved them to solusvm initially 2 days ago so using vzmigrate all was simple. When doing this and now monitoring load on Proxmox 3.4 there is practically no load at all. From a server that usually had 7 to 8 load to now 1 to 2 load this is amazing. Even IO wait has dropped drastically.
Very strange but I kinda knew it would drop moving from LXC to openvz.
The biggest issue we also had was when we did a restore of a VM on proxmox 4 the load went sky high and then froze other VMS during that process but on proxmox 3 it does not even budge and it runs and restores beautifully.
I'm still wondering why though. Could it be because of LXC vs openvz or is it because of LVM thin vs normal LVM setup? those are the only differences as its the same hardware. Very strange indeed.
Anyone ever do further tests on this and maybe have a solution. I really like proxmox 4 but the load and issues with cpanel servers put me off.
I know support for proxmox 3.4 is going bye bye but we can't afford to loose anymore clients over lxc still getting their. I'm glad cpu limits came out which is great but still seems to not be at that point of where openvz does it very well and does not pull cpu load of host.
