Hypervisors comparison

[dad264]

Hi everyone. I am putting together a matrix comparing the available Hypervisors/IaaS that compete with VMWare. Could the community help me fill out this information for ProxMox? Some of it may not be applicable as it's a VMWare term. I have very few answers so far. (Anything else worth adding would be appreciated)
Thanks!

the biggest comparable feature for Proxmox VS VMWare is cost per CPU for the features, VMware give a away a basic product for free but then you ahve to pay for the advanced features and if you need support you ahve to pay more. Proxmox is 100% free unless you need support - i've got a supoort contract and the proxmox team have been very helpful!

There has been an experiment on whether you can run 1000 openvz containers on a single system, and the experiment has been a success. The system showed a 97% idle cpu - try that with VMware.

as far as vRAM goes: KVM already supports ballooning and I have successfully tested it on a windows server 2008R2 guest. This way you can in fact hot add vRAM to the guest until you run out of physical RAM


Thin Disks (copy-on-write) [yes/no]: Yes/partly/if done manually: QCoW2 images for KVM support CoW. this technique however is not available for SAN storage if HA is a requirement. Works fine for NFS/iscsi though. If you need CoW for openvz - you need to store the openvz containers on a filesystem that has this capability, like ZFS


Guest OS support: Linux, Windows (what specifically?) See http://www.linux-kvm.org/page/Guest_Support_Status
openvz runs any x86/amd64 linux distribution that can run on a 2.6.32 kernel
