23 |
.SH DESCRIPTION |
24 |
This manual page documents the |
25 |
.B qemu-start |
26 |
command. |
27 |
.PP |
28 |
.\" TeX users may be more comfortable with the \fB<whatever>\fP and |
29 |
.\" \fI<whatever>\fP escape sequences to invode bold face and italics, |
30 |
.\" respectively. |
31 |
\fBqemu-start\fP is a small program that helps you start qemu in a safe and |
32 |
useful way. It presumes all qemu instances will run under the same |
33 |
user-id |
34 |
.RI ( qemu ). |
35 |
A group |
36 |
.I emulator |
37 |
is created; only members of this group are allowed to start qemu. Qemu is |
38 |
started with one ethernet interface, which is bound through a tap |
39 |
device. Xauthority data is |
40 |
automatically transferred if the DISPLAY variable is set. |
41 |
.SH PARAMETERS |
42 |
The first parameter |
43 |
.B TAPDEVNR |
44 |
is the number of the tap\-device. Use 0 for tap0, etc. See below how you |
45 |
safely can define tap devices. |
46 |
.PP |
47 |
The second parameter |
48 |
.B VLAN |
49 |
is the VLAN you want to add this adapter to. Usually, |
50 |
using 0 will do. |
51 |
.PP |
52 |
The third parameter |
53 |
.B SYSTEM |
54 |
is the system you want to emulate. Use "" if you want to use your current |
55 |
architecture; in this case, |
56 |
.B /usr/bin/qemm |
57 |
will be called. If you want to simulate some other type of system, specify |
58 |
it here; in that case, |
59 |
.B /usr/bin/qemm-system-SYSTEM |
60 |
will be called. |
61 |
.PP |
62 |
All other options and parameters are fed to qemm. |
63 |
.SH TAP DEVICE |
64 |
You must create a tap device for use by qemu. The nicest way of doing this |
65 |
is combining it with a bridge. This section describes how you can do this. |
66 |
.PP |
67 |
Edit |
68 |
.BR /etc/network/interfaces . |
69 |
Find the section where your current ethernet interface is described; we will |
70 |
assume here it is |
71 |
.IR eth0 . |
72 |
Change its name to |
73 |
.I br0 |
74 |
and add the following line to the stanza: |
75 |
.PP |
76 |
.I " " bridge_ports eth0 tap0 |
77 |
.PP |
78 |
You can add more |
79 |
.I tap |
80 |
devices later if you want. |
81 |
Now add a stanza for the new tap interface: |
82 |
.PP |
83 |
.I auto tap0 |
84 |
.br |
85 |
.I iface tap0 inet manual |
86 |
.br |
87 |
.I " " tunctl_user qemu |
88 |
.PP |
89 |
Finally, restart your netwerk by issuing a command |
90 |
.B /etc/init.d/networking restart |
91 |
|
92 |
