vProtect accesses KVM/Xen (stand-alone libvirt) hosts over SSH. Node can be installed outside of the environment.

KVM/Xen (libvirt) environments require to have correct entry in known_hosts on the node:

  • it must be known_hosts file that belongs to vprotect user

  • the algorithm must be set to ssh-rsa

  • make sure to have in your Node Configuration known_hosts file path set to the location that is accessible for vprotect user - default /opt/vprotect/.ssh/known_hosts

  • if your user/group used on KVM host is other than qemu:qemu then please provide them in hypervisor details form when you add/update hypervisor

KVM - VG scanning

Used with LVM-based VMs only. In order to allow VG scanning please make sure to have your LVM packages up to date on hypervisor. LVM reporting was one of the features added in RHEL/CentOS 7.3 and is used by vProtect to collect information about VGs.

KVM - full libvirt installation

Please make sure to follow steps in this section: Full versions of libvirt/qemu packages installation.
