Red Hat Enterprise Linux Server highlights virtualization advantages

The Red Hat Enterprise Linux Server With virtualization technology can provide support for fully virtualized clients, RHEL3, RHEL4, and RHEL5. Of course, it also supports third-party operating systems. In addition, the quasi-virtualization technology can provide higher performance, and now it supports the fifth update of RHEL5 and RHEL4. Fully virtualized client support has specific requirements on server hardware. It requires support for hardware-assisted Virtualization in Intel chip and AMD chip (Intel-VT and AMD-v),

The Red Hat Enterprise Linux Server With virtualization technology can provide fully virtualized client support, support RHEL 3, RHEL 4 and RHEL 5, and of course support third-party operating systems. In addition, the quasi-virtualization technology provides higher performance, and now it supports the fifth update of RHEL 5 and RHEL 4.

Fully virtualized client support has specific requirements on server hardware. It requires support for hardware-assisted Virtualization in Intel chip and AMD chip (Intel-VT and AMD-v ), however, the quasi-virtualization technology can adapt to any 32-bit x86 chip (which requires PAE support), 64-bit x86 chip, and even the anteng 2 system.

Red Hat Enterprise-level Linux Advanced Platform (Red Hat Enterprise Linux Advanced Platform) supports no upper limit of virtual machines (customer operating systems, the number of virtual machines that can be virtualized depends on the size of hardware resources. However, Red Hat Enterprise Linux only supports up to four virtual machines (customer operating systems ).

In addition, one of the advantages of Red Hat company virtualization is: If Red Hat Enterprise Linux is used as the host operating system, then, the same Red Hat Enterprise Linux operating system running on the virtual machine does not need to subscribe to the Red Hat Support Service. The support fee of the customer's operating system is automatically included in the support service of the host operating system. Third-party operating systems are still charged according to the policies of the relevant vendors. For example, if you use Microsoft Windows or other manufacturers' operating systems, you must pay the License fee.

Virt-manager is a virtual machine management system provided by RedHat. It is a graphical interface that includes functions related to virtual machines, such as creating, starting, stopping, suspending, continuing, and monitoring.

The Red Hat Enterprise LInux advanced platform includes Conga management software, which is a new management tool that provides Web-based storage, application, and server control, and is suitable for small and large cluster environments.
