1、virsh edit centos73 （更改前要将virsh
shutdown
centos73 ）
找到“memory”和“vcpu”标签，将
<name>centos73<
/name
>
<uuid>2220a6d1-a36a-4fbb-8523-e078b3dfe795<
/uuid
>
<memory unit=
'KiB'
>2097152<
/memory
>
<currentMemory unit=
'KiB'
>2097152<
/currentMemory
>
<vcpu placement=
'static'
>1<
/vcpu
>
改为：
<name>centos73<
/name
>
<uuid>2220a6d1-a36a-4fbb-8523-e078b3dfe795<
/uuid
>
<memory unit=
'KiB'
>3145728<
/memory
>
<currentMemory unit=
'KiB'
>3145728<
/currentMemory
>
<vcpu placement=
'static'
>2<
/vcpu
>
virsh define
/etc/libvirt/qemu/centos73
.xml 重定义使配置生效
重启虚拟机
virsh start centos73 --console
查看原配置信息
