-net nic　　其中，「-net nic」這個是必須的參數，代表這是一個網卡的配置。若是沒有，虛擬機啓動後就不會有網卡
-net user 用戶網絡模式
http://www.diyoms.com/cloud/836.html
http://qemu.weilnetz.de/qemu-doc.html#Using-TAP-network-interfaces

用戶模式客戶機能夠直接鏈接宿主機和外部網絡,並且徹底由qemu自身徹底實現，不依賴於(bridge,dnsmasq,iptables等),不須要root權限
Qemu使用slirp實現了一套Tcp/ip協議棧，並且用這個協議棧實現了一套虛擬的NAT網絡。
qemu-kvm默認使用：-net nic -net user
優勢:簡單、獨立性好、不須要root權限、客戶機網絡隔離性好。
缺點:
一、性能差
二、不支持部分網絡功能(如ICMP),因此不能再客戶機中使用ping命令測試,
三、不能從宿主機或外部網絡直接訪問客戶機

-net user

dhcpstart=addr  設置分配給客戶機的第一個Ip,在qemu內嵌的DHCP服務器中有16個IP地址能夠分配，默認是(如10.0.2.15~10.0.2.30)
dns=addr   指定虛擬的DNS地址，該地址不能與宿主機同樣，默認爲網絡中的第三個IP地址（如:10.0.2.3）

qemu-kvm   centos6u5.img  -m 1024  -smp 2 -net nic -net user,tftp=/root/tftp,hostfwd=tcp::5022-hostfwd=tcp::5080-:80

 

-net none       use it alone to have zero network devices. If no -net option
                is provided, the default is '-net nic -net user'
-net nic -net bridge

Linux/Multiboot boot specific:
-kernel bzImage use 'bzImage' as kernel image
-append cmdline use 'cmdline' as kernel command line
-initrd file    use 'file' as initial ram disk
-dtb    file    use 'file' as device tree image

-daemonize      daemonize QEMU after initializing
-echr chr       set terminal escape character instead of ctrl-a
During emulation, the following keys are useful:
ctrl-alt-f      toggle full screen
ctrl-alt-n      switch to virtual console 'n'
ctrl-alt        toggle mouse and keyboard grab

When using -nographic, press 'ctrl-a h' to get some help.

 

命令行參數解釋及實例

在qemu-kvm命令行中，添加「-nographic」參數能夠徹底關閉QEMU的圖形界面輸出，從而讓QEMU在該模式下徹底成爲簡單的命令行工具。而QEMU中模擬產生的串口被重定向到了當前的控制檯（console）中，因此若是在客戶機中對其內核進行配置從而讓內核的控制檯輸出重定向到串口後，就依然能夠在非圖形模式下管理客戶機系統或調試客戶機的內核。


在命令行直接安裝虛擬機
mount -o loop CentOS-6.5-x86_64-bin-DVD1.iso /mnt
qemu-img create -f qcow2 cs66.qcow2 8G
/usr/libexec/qemu-kvm  -boot order=dc -hda cs66.qcow2 -cdrom CentOS-6.5-x86_64-bin-DVD1.iso -m 1024 -nographic -append console=ttyS0 -kernel /mnt/isolinux/vmlinuz -initrd /mnt/isolinux/initrd.img
kill 掉上面的進程，重啓去掉一些參數再以下啓動
/usr/libexec/qemu-kvm  -boot order=dc -hda cs66.qcow2 -m 1024 -nographic

宿主機是cs72,虛擬機是cs65
安裝好系統以後，先用spice啓動
1.先啓動/usr/libexec/qemu-kvm -boot order=dc -hda cs65.qcow2 -m 1024 -spice port=9987,password=1234
2.windows的spice客戶端去鏈接，進去以後，vi /boot/grub/grub.cfg,在內核行後加入console=ttyS0而後保存關機
3.再加-nographic參數後啓動，/usr/libexec/qemu-kvm -boot order=dc -hda cs65.qcow2 -m 1024 -nographic
這樣就在宿主機本地啓動了


man qemu-kvm
debug/expert options

/usr/libexec/qemu-kvm -enable-kvm -monitor stdio

服務器啓動 /usr/libexec/qemu-kvm -boot dc -hda disk/cs65.qcow2 -m 1024 -vnc :2 -daemonize -net bridge -net nic -enable-kvm -monitor telnet:192.168.10.101:4444,server,nowait

客戶端鏈接 telnet 192.168.10.101 4444

/usr/libexec/qemu-kvm -boot dc -hda disk/cs65.qcow2 -m 1024 -vnc :2 -daemonize -net bridge -net nic -enable-kvm -monitor tcp:192.168.10.101:4445,server,nowait

nc 192.168.10.101 4445

    tcp – raw tcp sockets  #下面第2點，個人舉例是RAW TCP socket
    telnet – the telnet protocol is used instead of raw tcp sockets. This is the preferred option over tcp as you can break out of the monitor using Ctrl-] then typing quit. You can’t break out of the monitor like this after connecting with the raw socket option
    10.1.77.82 – Listen on this host/IP only. You can use 127.0.0.1 if you want to only allow connections locally. If you want to listen on any ip address on the server, just leave this blank so you end up with two consecutive colons ie 「::」 .
    4444 – port number to listen on.
    server – listening in server mode
    nowait – qemu will wait for a client socket application to connect to the port before continuing unless this option is used. In most cases you’ll want to use the nowait option.

cpu flag msr概念
Model Specific Register (MSR) as the name implies is model specific and may change from processor model number (n) to processor model number (n+1).
讀寫方法
MSR 是CPU 的一組64 位寄存器，能夠分別經過RDMSR 和WRMSR 兩條指令進行讀和寫的操做，前提要在ECX 中寫入MSR 的地址。對於RDMSR 指令，將會返回相應的MSR 中64bit 信息到(EDX：EAX)寄存器中；對於WRMSR 指令，把要寫入的信息存入(EDX：EAX)中，執行寫指令後，便可將相應的信息存入ECX 指定的MSR 中。MSR 的指令必須執行在level 0 或實模式下。
做用
MSR 整體來是爲了設置CPU 的工做環境和標示CPU 的工做狀態，包括溫度控制，性能監控等，具體來講，分爲如下幾項:

[root@localhost ~]# lsmod|grep papi
[root@localhost ~]# modprobe papi
modprobe: FATAL: Module papi not found.

[root@localhost ~]# lsmod |grep perfctr
[root@localhost ~]# modprobe perfctr
modprobe: FATAL: Module perfctr not found.

# modprobe perfctr 加載模塊
lsmod 顯示模塊
rmmod perfctr移除模塊
若perfctr模塊安裝成功後，你將看到perfctr模塊，而且你能夠在 /lib/modules/2.6.19-zkl-perfctr/kernel/drivers/perfctr中看到perfctr模塊perfctr.ko

須要使用PAPI獲得硬件級的數據，即與微指令相關的數據，
例如 L1/L2 cache miss、TLB miss、Cycle等，而PAPI須要perfctr（Performance-monitoring counters support）模塊的支持，
而Linux內核當中默認沒有perfctr模塊，而且perfctr只在某些內核上被支持，它其實是內核的一個補丁，須要從新編譯內核，打上補丁才能在內核上運行perfctr模塊。更多信息參考papi和perfctr的INSTALL文件。

PAPI (Performance Application Programming Interface),它是一套API,經過它能夠訪問CPU性能計數器的數據,
例如 L1/L2 Cache,CPU Cycle,CPU Instruction,TLB等.
