1.6. System Accounts

1.6.1. Red Hat Enterprise Virtualization Manager User Accounts

When the rhevm package is installed, a number of user accounts are created to support Red Hat Enterprise Virtualization. The user accounts created as a result of rhevm package installation are as follows. The default user identifier (UID) for each account is also provided:
  • 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.

1.6.2. Red Hat Enterprise Virtualization Manager Groups

When the rhevm package is installed, a number of user groups are created. The user groups created as a result of rhevm package installation are as follows. The default group identifier (GID) for each group is also listed:
  • The kvm group (GID 36). Group members include:
    • The vdsm user.
  • The ovirt group (GID 108). Group members include:
    • The ovirt user.

1.6.3. Virtualization Host User Accounts

When the vdsm and qemu-kvm-rhev packages are installed, a number of user accounts are created. These are the user accounts that are created on the virtualization host as a result of vdsm and qemu-kvm-rhev package installation. The default user identifier (UID) for each entry is also listed:
  • The vdsm user (UID 36).
  • The qemu user (UID 107).
  • The sanlock user (UID 179).
In addition Red Hat Enterprise Virtualization Hypervisor hosts define an admin user (UID 500). This admin user is not created on Red Hat Enterprise Linux virtualization hosts. The admin user is created with the required permissions to run commands as the root user using the sudo command. The vdsm user which is present on both types of virtualization hosts is also given access to the sudo command.

Important

The user identifiers (UIDs) and group identifiers (GIDs) allocated may vary between systems. The vdsm user however 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 then a conflict will arise during installation of the vdsm and qemu-kvm-rhev packages.

1.6.4. Virtualization Host Groups

When the vdsm and qemu-kvm-rhev packages are installed, a number of user groups are created. These are the groups that are created on the virtualization host as a result of vdsm and qemu-kvm-rhev package installation. The default group identifier (GID) for each entry is also listed:
  • 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.

Important

The user identifiers (UIDs) and group identifiers (GIDs) allocated may vary between systems. The vdsm user however 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 then a conflict will arise during installation of the vdsm and qemu-kvm-rhev packages.
