This article covers Virtualization Restrictions in RedHat Linux which are additional support and product restrictions of the virtualization packages.
The following notes apply to all versions of Red Hat Virtualization:
1. Supported limits reflect the current state of system testing by Red Hat and its partners. Systems exceeding these supported limits may be included in the Hardware Catalog after joint testing between Red Hat and its partners. If they exceed the supported limits posted here, entries in the Hardware Catalog are fully supported. In addition to supported limits reflecting hardware capability, there may be additional limits under the Red Hat Enterprise Linux subscription terms. Supported limits are subject to change based on ongoing testing activities.
2. These limits do not apply to Red Hat Enterprise Linux (RHEL) with KVM virtualization, which offers virtualization for low-density environments.
3. Guest operating systems have different minimum memory requirements. Virtual machine memory can be allocated as small as required.
