1. Create a new virtual machine and choose its hypervisor as qemu.

2. Name it "JOS"

3. Configure the hard disk and memory

4. virsh dumpxml JOS > jos.xml

5. Edit the jos.xml like below

 1 <domain type='qemu'>
 2   <name>JOS</name>
 3   <uuid>8e7bb147-9da1-49e0-90b7-5011c54ae9a6</uuid>
 4   <memory>262144</memory>
 5   <currentMemory>262144</currentMemory>
 6   <vcpu>1</vcpu>
 7   <os>
 8     <type arch='i686' machine='pc'>hvm</type>
 9     <boot dev='hd'/>
10   </os>
11   <features>
12     <acpi/>
13     <apic/>
14     <pae/>
15   </features>
16   <clock offset='utc'/>
17   <on_poweroff>destroy</on_poweroff>
18   <on_reboot>restart</on_reboot>
19   <on_crash>restart</on_crash>
20   <devices>
21     <emulator>/home/guzhongshu/Project/Jos/qemu_wrapper.sh</emulator>
22     <disk type='file' device='disk'>
23       <source file='/home/guzhongshu/Project/Jos/obj/kern/bochs.img'/>
24       <target dev='hda' bus='ide'/>
25     </disk>
26     <disk type='file' device='disk'>
27       <source file='/home/guzhongshu/Project/Jos/obj/fs/fs.img'/>
28       <target dev='hdb' bus='ide'/>
29     </disk>
30     <interface type='user'>
31         <mac address='52:54:00:12:34:56'/>
32         <model type='i82559er'/>
33     </interface>
34     <parallel type='stdio'>
35       <target port='0'/>
36     </parallel>
37     <serial type='pty'>
38       <target port='0'/>
39     </serial>
40     <console type='pty'>
41       <target port='0'/>
42     </console>
43     <input type='mouse' bus='ps2'/>
44     <graphics type='vnc' port='-1' autoport='yes' keymap='en-us'/>
45   </devices>
46 </domain>

6. virsh define jos.xml

7. Add file qemu_wrapper.sh because some arguments can not be added in the xml. We need to use some trick.

#!/bin/sh
  exec /usr/local/bin/qemu -redir tcp:8080::80 -redir tcp:4242::10000 "$@" -debug-e100 -pcap slirp.cap
