Sir in proxmox can I create KVM and OpenVZ vps both? Means one or two vps will be on KVM and another one or two VPS on openVZ. Is it possible on proxmox? In xenserver it is possible but I do not know about proxmox.
Upload from your desktop
If you already got Virtually Appliances you can upload them via the upload button. To install a virtual machine from an ISO image (using KVM full virtualization) just upload the ISO file via the upload button.
Directly to file system
Templates and ISO images are stored on the Proxmox VE server (see /var/lib/vz/template/cache for openvz templates and /var/lib/vz/template/iso for ISO images). You can also transfer templates and ISO images via secure copy (scp) to these directories. If you work on a windows desktop, you can use a graphical scp client like winscp.
wget -P /var/lib/vz/template/iso/ http://mirror.nextlayer.at/centos/6.7/isos/x86_64/CentOS-6.7-x86_64-minimal.iso
