Kimisufi and VT Virtualisation??
The dutch Kimisufi brand, isgenoeg.nl now also has the new lineup. I'm interested in it, want to run Proxmox on it. But the specs say it has no "VT Virtualisation". Does that mean it lacks intel VT-x/AMD-V? And if so, how is OpenVZ performance, and, how is KVM/XEN performance on a machine without VT-X/AMD-V

@raymii right, it doesn't have hardware support for virtualization - you can run software emulated virtualization if you can live with the performance hit. Without hw support, my qemu tests show 100% CPU usage during qemu boot of a Debian guest and 80% during login. After that it settles down but would not recommend for compiling stuff etc.
Openvz doesn't use hardware virt - it's a regular linux kernel with a patch and userland tools for ovz mgmt.
OpenVZ works on anything, don't need VT.
KVM without hardware virtualization would run so slow that... i can't even figure out an appropriate comparison.
I have run vmware server years ago (in the vmware server 1.0.x days) on CPUs without hardware virtualization - it worked quite well. Don't know how the modern vmware versions work.
isgenug.de (Germany/Austria/Switzerland/Liechtenstein) has the new one as well now
Yes, right. Already ordered the i3 with 8GB RAM - but haven't received it yet.
So it would be best to go with a model there that supports VT if I want to do KVM, and else just OpenVZ. Thanks for the info!
Shame they have limited the amount of ipv4's on the kimsufi brand though
You can go Xen-PV, I deployed XCP (freeware version of XenServer) on an atom and works really well.

That's right, also the bandwidth.
The main OVH brand has 95 percentile bandwidth now (yay!) and they've thrown out ipv4 for Kimsufi and one-off payment for ipv4 with professional use enabled.
XenServer is free, they just limit the hell out of you just so you buy a license. (stupid Citrix)
The free version of Xenserver for me is Proxmox :P. Xen-PV is like openvz then?
Sorry, that statement is invalid :P
I love Proxmox, here is the difference
Proxmox <---> XenServer (Citrix is only giving it free with limited features in the hope you pay for that crap)
OpenVZ <----> Xen PV (exactly like OpenVZ, just written differently, better RAM allocation and shittier community than OpenVZ)
KVM <-------> Xen HVM (even VirtualBox beats Xen HVM, it's a ruined fork of QEMU)
@BronzeByte I know it is, and I also know they use different hypervisors. You're basicly saying that you don't like Xen? :P
Yes, he continues to bash Xen even tho I pointed out major flaws in his reasoning here: http://www.lowendtalk.com/discussion/5703/hi-we-are-a-web-hosting-voip-hosting-company-moving-into-the-world-of-vps#Item_27
I dont know the reasons behind that but it starts to look fishy, especially since he didnt reply my post, just goes some other thread to spread unfounded rumours.
Also XenServer might be free, but I was not talking about that, I was talking about the really free (opensource) version called XCP (Xen Cloud Platform).
