5. Masking Virtuozzo Linux as CentOS or Redhat Enterprise Linux

As certain software requires specific Linux distributions to run, you can mask Virtuozzo Linux as CentOS or Redhat Enterprise Linux to meet those requirements.

Use the vz-chameleon-distro script shipped by default. For example, to mask Virtuozzo Linux as CentOS, run

# vz-chameleon-distro --enable centos
CentOS chameleon mode is enabled

The release information will change accordingly:

# cat /etc/os-release
NAME="CentOS Linux"
VERSION="8"
ID="centos"
ID_LIKE="rhel fedora"
VERSION_ID="8"
PLATFORM_ID="platform:el8"
PRETTY_NAME="CentOS Linux 8"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:centos:centos:8"
HOME_URL="https://centos.org/"
BUG_REPORT_URL="https://bugs.centos.org/"
CENTOS_MANTISBT_PROJECT="CentOS-8"
CENTOS_MANTISBT_PROJECT_VERSION="8"

To mask Virtuozzo Linux as Redhat Enterprise Linux, run

# vz-chameleon-distro --enable rhel
RHEL chameleon mode is enabled

The release information will change accordingly:

# cat /etc/os-release
NAME="Red Hat Enterprise Linux"
VERSION="8.3 (Ootpa)"
ID="rhel"
ID_LIKE="fedora"
VERSION_ID="8.3"
PLATFORM_ID="platform:el8"
PRETTY_NAME="Red Hat Enterprise Linux 8.3 (Ootpa)"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:redhat:enterprise_linux:8.3:GA"
HOME_URL="https://www.redhat.com/"
BUG_REPORT_URL="https://bugzilla.redhat.com/"
REDHAT_BUGZILLA_PRODUCT="Red Hat Enterprise Linux 8"
REDHAT_BUGZILLA_PRODUCT_VERSION=8.3
REDHAT_SUPPORT_PRODUCT="Red Hat Enterprise Linux"
REDHAT_SUPPORT_PRODUCT_VERSION="8.3"

To stop masking, run

# vz-chameleon-distro --disable
Chameleon mode is disabled

The release information will be reverted:

# cat /etc/os-release
NAME="Virtuozzo Linux"
VERSION="8"
ID="virtuozzo"
ID_LIKE="rhel fedora"
VERSION_ID="8"
PLATFORM_ID="platform:el8"
PRETTY_NAME="Virtuozzo Linux"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:virtuozzoproject:vzlinux:8"
HOME_URL="https://www.vzlinux.org"
