支持海光CSV3虚拟机迁移功能。

**CSV3虚拟机迁移说明：假设主机HostA是迁移源主机，主机HostB是迁移目标主机** 
 **HostB** 
 启动CSV3接收端虚拟机guestB，假设迁移监听端口6666
 $sudo qemu-system-x86_64 \
        -hda ./AnolisOS-8.6-x86_64-ANCK-gpt.qcow2 \
        -drive  if=pflash,format=raw,unit=0,file=./OVMF_CODE.fd,readonly=on \
        -m 1024M \
        -nographic \
        -enable-kvm \
        -cpu host \
        -smp 4 \
        -monitor pty \
        -object sev-guest,id=sev0,policy=0x45,cbitpos=47,reduced-phys-bits=5 \
        -machine memory-encryption=sev0 \
        -incoming tcp:0:6666 \
        -qmp tcp:localhost:4445,server,nowait

新建主机shell

$ sudo ./hag csv export_cert_chain

$cat hsk.cert hrk.cert > vendor_cert.bin

$cat pek.cert oca.cert cek.cert > plat_cert.bin

$cat pdh.cert > pdh.bin

$base64 -w 0 vendor_cert.bin > vendor_cert.base64

$base64 -w 0 plat_cert.bin > plat_cert.base64

$base64 -w 0 pdh.bin > pdh.base64

$sudo chmod 666 *.base64

$cp -a *.base64 /tmp

**HostA** 
 启动CSV3虚拟机guestA，等待进入登录状态（因为虚拟机内核未运行时，无法使能迁移功能），假设qmp监听端口4444
 $sudo qemu-system-x86_64 \
        -hda ./AnolisOS-8.6-x86_64-ANCK-gpt.qcow2 \
        -drive  if=pflash,format=raw,unit=0,file=./OVMF_CODE.fd,readonly=on \
        -m 1024M \
        -nographic \
        -enable-kvm \
        -cpu host \
        -smp 4 \
        -object sev-guest,id=sev0,policy=0x45,cbitpos=47,reduced-phys-bits=5 \
        -machine memory-encryption=sev0 \
        -name src \
        -qmp tcp:localhost:4444,server,nowait

$scp HostB:/tmp/*.base64 /tmp/
