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).
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.
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.
