Proxy Operating System

The Virtual Server Agent (VSA) can be installed on virtual machines with the following operating systems:

  • RHEL 6.5, RHEL 7.1, 7.2
  • Microsoft Windows Server 2008 R2

  • Microsoft Windows Server 2016

Note: To use a Red Hat 7 proxy, use the following commands to disable lvmetad. Having lvmetad running interferes with HotAdd operations during backup and recovery.

  1. Disable and stop the lvm2-lvmetad service by running the following commands:

    systemctl disable lvm2-lvmetad
    systemctl stop lvm2-lvmetad

  2. Disable and stop the lvm2-lvmetad.socket service by running the following commands:

    systemctl disable lvm2-lvmetad.socket
    systemctl stop lvm2-lvmetad.socket

  3. Disable lvmetad in the LVM config file by running the following command:

    edit /etc/lvm/lvm.conf to include use_lvmetad = 0


Network File System (NFS), iSCSI, and Fibre Channel

Red Hat Guest Tools

Red Hat guest tools must be installed in VSA proxy machines.
