Appendix F. System Accounts

F.1. System Accounts

F.1.1. Red Hat Virtualization Manager User Accounts

A number of system user accounts are created to support Red Hat Virtualization when the rhevm package is installed. Each system user has a default user identifier (UID). The system user accounts created are:

  • The vdsm user (UID 36). Required for support tools that mount and access NFS storage domains.
  • The ovirt user (UID 108). Owner of the ovirt-engine Red Hat JBoss Enterprise Application Platform instance.
  • The ovirt-vmconsole user (UID 498). Required for the guest serial console.

F.1.2. Red Hat Virtualization Manager Groups

A number of system user groups are created to support Red Hat Virtualization when the rhevm package is installed. Each system user group has a default group identifier (GID). The system user groups created are:

  • The kvm group (GID 36). Group members include:
  • The vdsm user.
  • The ovirt group (GID 108). Group members include:
  • The ovirt user.
  • The ovirt-vmconsole group (GID 498). Group members include:
  • The ovirt-vmconsole user.

F.1.3. Virtualization Host User Accounts

A number of system user accounts are created on the virtualization host when the vdsm and qemu-kvm-rhev packages are installed. Each system user has a default user identifier (UID). The system user accounts created are:

  • The vdsm user (UID 36).
  • The qemu user (UID 107).
  • The sanlock user (UID 179).
  • The ovirt-vmconsole user (UID 498).
Important

The user identifiers (UIDs) and group identifiers (GIDs) allocated may vary between systems. The vdsm user is fixed to a UID of 36 and the kvm group is fixed to a GID of 36.

If UID 36 or GID 36 is already used by another account on the system a conflict will arise during installation of the vdsm and qemu-kvm-rhev packages.

F.1.4. Virtualization Host Groups

A number of system user groups are created on the virtualization host when the vdsm and qemu-kvm-rhev packages are installed. Each system user group has a default group identifier (GID). The system user groups created are:

  • The kvm group (GID 36). Group members include:
  • The qemu user.
  • The sanlock user.
  • The qemu group (GID 107). Group members include:
  • The vdsm user.
  • The sanlock user.
  • The ovirt-vmconsole group (GID 498). Group members include:
  • The ovirt-vmconsole user.
Important

The user identifiers (UIDs) and group identifiers (GIDs) allocated may vary between systems. The vdsm user is fixed to a UID of 36 and the kvm group is fixed to a GID of 36.

If UID 36 or GID 36 is already used by another account on the system a conflict will arise during installation of the vdsm and qemu-kvm-rhev packages.
