问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 1 year ago . Improve this question I am building a project in which i have to extract the pages which are dirty of Virtual Machine running on top of qemu-kvm.I downloaded the qemu source code but could not able to understand this properly because source code is very big.So please give me guide

vmware workstation14嵌套安装kvm

时光总嘲笑我的痴心妄想 提交于 2021-02-09 08:54:48
1.前言 我在2017-11-06使用virtualbox安装了centos,然后嵌套kvm(win7),链接地址如下: https://www.cnblogs.com/tcicy/p/7790956.html 今天想在virtualbox中再耍一遍的时候,发现egrep -o '(vmx|svm)' /proc/cpuinfo执行不出结果。。。 然后Google了半天,发现virtualbox只支持嵌套,而且是个10多年的老bug了~~~~!!!无语!难道我2017-11-06用的是假的virtualbox??? 不过,想做实验,只能硬着头皮装VMware workstation。。。。。真不想装啊!!! 安装VMware workstation14,安装centos7.xmini,一定要配置以下 然后执行以下命令就可以安装kvm了 egrep -o '(vmx|svm)' /proc/cpuinfo 因为是mini安装,要啥啥没有,所以装点必须的 1.1安装调试基础环境 yum install -y epel-release sysstat net-tools mlocate 安装kvm程序及其环境 yum install -y qemu-kvm qemu-kvm-tools libvirt virt-install virt-top 可以安装的程序很多 qemu- kvm #

kvm创建虚拟机

此生再无相见时 提交于 2021-02-08 23:49:49
本篇内容为通过kvm和virsh创建虚拟机 本次创建虚拟机的方式是通过virt-install命令创建。 首先配置环境 安装Centos7 配置IP,将网络调通。 配置yum源。(参考 https://www.cnblogs.com/renpingsheng/p/7845096.html ) 我的练习环境是通过vmware虚拟机实现的,所以需要注意的是Centos装好之后需要关机,并勾选虚拟机 cpu处理器的虚拟化设置。(虚拟化Intel VT-x/EPT或AMD-V/RVI(V)) 关闭防火墙: firewall-cmd --state systemctl status firewalld.service systemctl stop firewalld.service systemctl disable firewalld.service 如果不关闭防火墙可能会出现之后安装虚拟机的过程中vnc无法连接的情况。 grep -E '(vmx|svn)' /proc/cpuinfo 检查是否支持虚拟化 安装kvm及相关组件: yum install -y qemu-kvm qemu-kvm-tools libvirt yum install -y virt-install 说明: qemu-kvm是实现模拟硬件的。 qemu-kvm-tools是qemu-kvm的工具包。

Qemu not responding after upgrading to macOS Catalina

核能气质少年 提交于 2021-02-07 21:05:16
问题 After upgrading my Mac to Catalina, I can't use qemu anymore. Whenever I try to start it, it just hangs. The menu bar also doesn't respond while the qemu window is active. Running qemu-system-i386 --help does work though. Qemu version: 4.1.0 Edit: Passing -nographic fixes the issue. 回答1: This is the result of a change in behaviour in Catalina which breaks an assumption in the design of the QEMU Cocoa front-end. We've put in a change to the QEMU code (upstream git commit dff742ad27efa474)

Write to QEMU guest system registers & memory?

一笑奈何 提交于 2021-02-06 13:58:09
问题 How do you write to the processor registers and specific memory addresses of a virtual system running in QEMU? My desire would be to accomplish this from a user space program running outside of QEMU. This would be to induce interrupts and finely control execution of the processor and virtual hardware. The QEMU Monitor is supposed to read parameters or do simple injects of mouse or keyboard events, but I haven't seen anything about writing. 回答1: GDB server within QEMU Monitor seems to be the
