Also included are host configuration details and instructions for installing guest virtual machines of different types, PCI device configuration and SR- IOV. What is in This Guide? This guide provides information on installing virtualization software and configuring guest machines on a Red Hat Enterprise Linux virtualization host. The initial chapters in this guide outline the prerequisites to enable a Red Hat Enterprise Linux host machine to deploy virtualization. System requirements, compatible hardware, support and product restrictions are covered in detail. Guest virtual machine installation is covered in detail starting from Chapter 6, Guest Virtual Machine Installation Overview, with procedures for installing fully virtualized Red Hat Enterprise Linux guests and Windows paravirtualized guests using virt- manager and virsh. More detailed information on networking, PCI device configuration, SR- IOV, KVM guest timing management, and troubleshooting help for libvirt and SR- IOV is included later in the guide. Chapter 2. System Requirements. This chapter lists system requirements for successfully running virtual machines, referred to as VMs on Red Hat Enterprise Linux 6. Virtualization is available for Red Hat Enterprise Linux 6 on the Intel 6. AMD6. 4 architecture. The KVM hypervisor is provided with Red Hat Enterprise Linux 6. Minimum system requirements. Technical articles, content and resources for IT Professionals working in Microsoft technologies. Directory of hundreds of tools for monitoring and analyzing network traffic. GB free disk space. GB of RAM. Recommended system requirements. One processor core or hyper- thread for the maximum number of virtualized CPUs in a guest virtual machine and one for the host. GB of RAM plus additional RAM for virtual machines. GB disk space for the host, plus the required disk space for each virtual machine. Most guest operating systems will require at least 6. GB of disk space, but the additional storage space required for each guest depends on its image format. For guest virtual machines using raw images, the guest's total required space (total for raw format) is equal to or greater than the sum of the space required by the guest's raw image files (images), the 6. GB space required by the host operating system (host), and the swap space that guest will require (swap). Equation 2. 1. Calculating required space for guest virtual machines using raw imagestotal for raw format = images + host + swap. For qcow images, you must also calculate the expected maximum storage requirements of the guest (total for qcow format), as qcow and qcow. To allow for this expansion, first multiply the expected maximum storage requirements of the guest (expected maximum guest storage) by 1. Equation 2. 2. Calculating required space for guest virtual machines using qcow imagestotal for qcow format = (expected maximum guest storage * 1. Guest virtual machine requirements are further outlined in the Red Hat Enterprise Linux 6 Virtualization Administration Guide in Chapter 6. Overcommitting with KVM. Calculating Swap Space. Using swap space can provide additional memory beyond the available physical memory. The swap partition is used for swapping underused memory to the hard drive to speed up memory performance. The default size of the swap partition is calculated from the physical RAM of the host. KVM Requirements. The KVM hypervisor requires. Intel processor with the Intel VT- x and Intel 6. AMD processor with the AMD- V and the AMD6. Refer to the Red Hat Enterprise Linux 6 Virtualization Administration Guide to determine if your processor has the virtualization extensions. Storage Support. The guest virtual machine storage methods are. LUNs. LVM partitions. NFS shared file systems. GFS2 clustered file systems. Fibre Channel- based LUNs, and. Fibre Channel over Ethernet (FCo. E). Chapter 3. KVM Guest Virtual Machine Compatibility. To verify whether your processor supports the virtualization extensions and for information on enabling the virtualization extensions if they are disabled, refer to the Red Hat Enterprise Linux Virtualization Administration Guide. Red Hat Enterprise Linux 6 Support Limits. Red Hat Enterprise Linux 6 servers have certain support limits. The following URLs explain the processor and memory amount limitations for Red Hat Enterprise Linux. The following URL is a complete reference showing supported operating systems and host and guest combinations. Supported CPU Models. Every hypervisor has its own policy for which CPU features the guest will see by default. The set of CPU features presented to the guest by QEMU/KVM depends on the CPU model chosen in the guest virtual machine configuration. CPU models but there are other models (with additional features) available. Red Hat Enterprise Linux 6 supports the use of the following QEMU CPU model definitions. This is only a partial file, only containing the CPU models. The XML file has more information (including supported features per model) which you can see when you open the file yourself - ->.

A full list of supported CPU models and recognized CPUID flags can also be found using the qemu- kvm - cpu ? Chapter 4. Virtualization Restrictions. This chapter covers additional support and product restrictions of the virtualization packages in Red Hat Enterprise Linux 6. The following restrictions apply to the KVM hypervisor. Maximum v. CPUs per guest. The maximum amount of virtual CPUs that is supported per guest varies depending on which minor version of Red Hat Enterprise Linux 6 you are using as a host machine. The release of 6. Currently with the release of 6. CPUs per guest is supported. Constant TSC bit. Systems without a Constant Time Stamp Counter require additional configuration. Refer to Chapter 1.
