Appendix F: System Accounts

oVirt Engine User Accounts

A number of system user accounts are created to support oVirt when the ovirt-engine 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 JBoss Enterprise Application/Wildfly Platform instance.

  • The ovirt-vmconsole user (UID 498). Required for the guest serial console.

oVirt Engine Groups

A number of system user groups are created to support oVirt 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.

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.

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.
