從 CLI 創建虛擬機？(KVM)

如何從 CLI創建虛擬機？

創建虛擬機

First, download an ISO cd image of some OS you want to run. For Ubuntu, you can find these at:

    http://www.ubuntu.com/getubuntu/download 

Double click on the name of the host. The Status column should read Active

Right click on the name of the host, and select New
This will start a wizard to guide you through the rest of your VM creation
    Enter your virtual machine details

        Name: foo

        Choose Local install media (ISO image or CDROM), or you can use another method if you know what you're doing

        Forward 
    Locate your install media

        Use ISO image

        Browse to find the ISO you downloaded earlier

        Optional: Select the matching OS Type

        Optional: Select the matching Version

        Forward

主要是為了我自己的啟迪。

只需使用：

virt-install \
--name vm_name \
--ram=2048 \
--vcpus=2 \
--disk pool=guest_images,size=30,bus=virtio,format=qcow2 \
--cdrom /var/iso/debian.iso \
--network bridge=kvmbr0,model=virtio \
--graphics vnc,listen=0.0.0.0,password=Qwerty1234 \
--boot cdrom,hd,menu=on

where /var/iso/debian.iso- iso 映像的路徑

guest_images- 磁碟池，需要在vm之前創建

我經常通過這種 qemu 命令以舊方式使用 qemu-kvm：

qemu-img create mydisk.img 10G

qemu-system-x86_64 -boot d -cdrom image.iso -m 512 -hda mydisk.img

virsh 將啟動 qemu-kvm。但它需要一些配置文件。有時繞過所有這些 xml 行並啟動 vm 會更容易。
