ubuntu建立kvm虛擬機

CPU虛擬化支持

[root@ubuntu~]# egrep -o '(vmx|svm)' /proc/cpuinfo
vmx
vmx
vmx
vmx

KVM環境

[root@ubuntu ~]# apt-get install qemu-kvm qemu-system libvirt-bin virt-manager bridge-utils vlan
[root@ubuntu ~]# service libvirt-bin status
libvirt-bin start/running, process 1442

ACPI 高級配置和電源管理接口，經過這個服務來執行電源關閉的動做

[root@ubuntu ~]# apt-get install acpid 
[root@ubuntu ~]# service acpid status
acpid start/running, process 1364

製做iso鏡像

[root@ubuntu ~]# dd if=/dev/sr0 of=/data/iso/CentOS-V6.5.23.iso          
1801312+0 records in
1801312+0 records out
922271744 bytes (922 MB) copied, 29.0399 s, 31.8 MB/s

製做磁盤鏡像

[root@ubunt ~]# qemu-img create -f raw /data/raw/disk01.raw  10G
Formatting '/data/raw/disk01.raw', fmt=raw size=10737418240

建立虛擬機

[root@ubuntu ~]# virt-install \
>     --name=CentOS-V6.5.23-server01 \
>     --virt-type=kvm \
>     --ram=1024 \
>     --cdrom=/data/iso/CentOS-V6.5.23.iso   \
>     --disk path=/data/raw/disk01.raw \
>     --network network=default \
>     --graphics vnc,listen=0.0.0.0 \
>     --noautoconsole
