This PR introduces support for cloudstack-agent on KVM on the s390x and cloudstack-management-server on s390x architecture. KVM is supported on s390x (IBM Z and LinuxONE) architecture, Linux KVM Processor Support Page. I have built a new s390x version of the System VM template: [ Refer: ...
Returns: number of msrs successfully returned; -1 on error When used as a system ioctl: Reads the values of MSR-based features that are available for the VM. This is similar to KVM_GET_SUPPORTED_CPUID, but it returns MSR indices and values. The list of msr-based features can be obtain...

It has supported x86, PowerPC and so on, but not supported arm architecture yet. Consequently, this paper introduces a new system virtualization based on KVM for ARM V6 architecture, and emphasizes the content about processor virtualization. KVM-ARM lightly modified guest kernel's source code by...
NUMA是英文 Non Uniform Memory Access Architecture 的缩写,意思就是非统一内存访问,它是一种解决多CPU共同工作的解决方案。我们知道现在的服务器配置都比较高了,CPU很多都是多路多核的,而且CPU是需要跟存储器进行数据交互的,以往的年代,那时候的CPU运算速率不高,而且都是单CPU模式,那么存储器里的数据要放到CPU里...
#if defined(LINUX) && PROCESSOR_ARCHITECTURE_X86 /* Set the precision FPU to double precision */ // fpu_control_t cw = (_FPU_DEFAULT & ~_FPU_EXTENDED) | _FPU_DOUBLE; // _FPU_SETCW(cw); #endif 1. 2. 3. 4. 5. 这样,编译的时候才不会出现错误,但也不支持浮点数了。
QEMU会模拟多种Processor architectures, 常用的是PC (x86 or x86_64 processor), Mac99 PowerMac (PowerPC processor), Sun4u/Sun4v (64-bit Sparc processor), MIPS magnum (64-bit MIPS processor) 通过下面的命令我们可以列出支持的PC bus architecture ...
目前,虚拟机的主流镜像格式有raw、cow、qcow、qcow2以及vmdk,下面,我就详细介绍一下这些主流的虚拟机镜像格式。 1、raw格式 raw格式是一种很早的镜像格式,格式比较原始、简单,性能上也还不错。并且raw格式镜像的一个突出好处是它支持转换成其他格式的镜像,或者作为其他格式镜像转换的中间格式。但是,raw格式的一个突...
This is only possible when the target architecture is supported by the host CPU. However, KVM introduced one more mode called the guest mode! In nutshell, guest mode is the execution of guest system code. It can either run the guest user or the kernel code. With the support of ...
