当启动虚拟机的时候,以下的XML扩展允许给qemu命令行参数。为了使用XML扩展,需要增加一个XML namespace为http://libvirt.org/schemas/domain/qemu/1.0。一般给这namespace取名为qemu,需要增加一个元素<qemu:commandline>,还有两个子元素: qemu:arg当启动虚拟机的时候,向qemu进行提供一个命令行参数,将参数放在XML的va...

The application uses thesocketbackend provided by QEMU. It can be configured for the QEMU virtual machine using the following command line arguments of QEMU: -netdev socket,listen=:12345 -chardev socket,server=on,wait=off,host=0.0.0.0,port=23456 ...
you can alter that using a kernel command line option such as "console=ttyAMA0". (Try "man bootparam" or see the documentation of your boot loader (lilo or loadlin) about how to pass options to the kernel at boot time.) AMBA_PL011是arm的一个标准串口设备, qemu 的输出就是模拟的这个...

The required arguments for QEMU are encoded via a<qemu:commandline>stanza, with each argument getting its own<qemu:arg>definition. Place this anywhere inside the<domain>stanza. <qemu:commandline><qemu:argvalue='-cpu'/><qemu:argvalue='host,+sgx,+sgxlc'/><qemu:argvalue...
