[qemu][kvm] 在一个vmware虚拟机里安装qemu-kvm虚拟机

说起来这个需求,简直是傻傻的。但却实实在在的摆在我的面前。。。。 VM无外乎就是为了模拟场景:我现在要的场景就是一台很多个core的linux主机。但是我只有一个装了windows的笔记本。上边有一个VMware,而VMware又不能模拟超过hostCPU个数的guestCPU数。 所以,用KVM在VMware里模拟一下。 CentOS 安装 qemu: [root@D128 VM]# yum install qemu qemu-kvm 首先,默认情况下,vmware没有开启虚拟化支持。在guest里运行kvm会报错: [root@D128 j]# ./start.sh (process:2651): GLib-WARNING **: gmem.c:483: custom memory allocation vtable not supported Could not access KVM kernel module: No such file or directory failed to initialize KVM: No such file or directory 可以在VMware的软件外部设置里,开启虚拟化支持,如图: 最后,晒一下我的启动脚本: [root@D128 j]# cat start.sh qemu-system-x86_64 -enable-kvm \

ARM Interrupt Handling in QEMU

 ̄綄美尐妖づ 提交于 2020-01-02 04:39:30
问题 I'm trying to understand how QEMU handles interrupts for ARM processors. I have a bare metal binary blob (ie, not linux -- just some assembly code) which was built for a ARM1176. When run in QEMU, during initialisation the code in the binary blob sets bit 13 of the CPSR indicating that the interrupt vector table is located at 0xFFFF0000 . Hooking up GDB and dumping the instructions at that address, I can indeed see the corresponding interrupt vector table. On an IRQ, it jumps to 0xFFFF0018 ,

问题 I am currently taking an operating systems class and I need to use qemu to run a small operating system that my professor provided. I am trying to use qemu within an ubuntu 12.04 virtual machine on virtualbox on my macbook air 5.2. I know the problems I am having probably have to do with nested virtualization but the specific error I get when I try to run qemu is: Could not access the KVM kernel module: No such file or directory failed to initialize KVM: no such file or directory Back to tcg

日常管理概述 接着上一篇,这篇博客主要描述kvm日常管理中使用的一些方法和命令。 kvm的管理主要有以下几个方面: kvm状态和配置管理:包括kvm虚拟机的开启、关闭、挂起、恢复,配置文件的导出导入和编辑,还有虚拟机重命名等 磁盘管理:包括虚拟机磁盘的创建、信息查看、格式转换、容量更改以及格式化、挂载使用 kvm的console连接 kvm开机自启动 kvm快照和克隆 另外,网络模式更改和热添加技术在下一篇描述 kvm状态管理 开启、关闭和查看 状态查看 [root@kvm1 opt]# virsh list Id Name State ---------------------------------------------------- 2 Centos7 running [root@kvm1 opt]# virsh list --all Id Name State ---------------------------------------------------- 2 Centos7 running 参数说明:加上--all参数可以显示所有虚拟机,如果不加,就不能显示处于关闭状态的虚拟机了。这个在下面关闭虚拟机的例子中演示 关闭 [root@kvm1 opt]# virsh shutdown Centos7 Domain Centos7 is being shutdown

How to use qemu to run a non-gui OS on the terminal?

问题 I want to run some programs on the High Performance Computer (With 8-core processor) in my department. Now I use that machine with ssh using terminal. The machine has Red Hat linux installed on it. But my programs need to run on Solaris. I use Nexenta Solaris for x86. Can qemu be used to run Nexenta Solaris on that machine through terminal. I need to convince the administrator that it can, otherwise he won't install qemu on that machine and therefore allow me to use Solaris through a virtual

Run Android app in qemu-arm?

我是研究僧i 提交于 2019-12-30 20:51:25
问题 There are very few articles on this topic on the net, so I'm asking here if it makes sense, what I'm doing. I'm trying to partition virtual disk just the way android does it, mount android images (system, root etc) only to run android app on Linux in qemu-arm. Have you done it? Is it possible? Will the performance be better than in default Android emulator? I'm sorry if the question is stupid. 回答1: qemu-system-arm actually supports running certain versions of Android. The following link has
