NAME

6       virt-p2v-make-disk - Build the virt-p2v disk using virt-builder
7

SYNOPSIS

9        virt-p2v-make-disk -o /dev/sdX [os-version]
10

DESCRIPTION

12       virt-p2v(1) converts a physical machine to run virtualized on KVM,
13       managed by libvirt, OpenStack, oVirt, Red Hat Enterprise Virtualisation
14       (RHEV), or one of the other targets supported by virt-v2v(1).
15
16       virt-p2v-make-disk is a script which creates a bootable disk image or
17       USB key containing virt-p2v.  It uses virt-builder(1) to do this, and
18       is just a small shell script around virt-builder.
19
20       The required -o parameter specifies where the output should go, for
21       example to a USB key (eg. "-o /dev/sdX") or to a file.  If you pass a
22       device name, then the existing contents of the device will be erased.
23
24       The root user on the disk image uses "p2v" as its initial password.
25
26   "os-version" parameter
27       The optional "os-version" parameter is the base Linux distro to use for
28       the operating system on the ISO.  If you don't set this parameter, the
29       script tries to choose a suitable default for you.  Most users should
30       not use the "os-version" parameter.
31
32       The base OS selected for virt-p2v is not related in any way to the OS
33       of the physical machine that you are trying to convert.
34
35       To list possible "os-version" combinations, do:
36
37        virt-builder -l
38

EXAMPLES

40       Write a virt-p2v bootable USB key on /dev/sdX (any existing content on
41       /dev/sdX is erased):
42
43        virt-p2v-make-disk -o /dev/sdX
44
45       Write a virt-p2v bootable virtual disk image, and boot it under qemu:
46
47        virt-p2v-make-disk -o /var/tmp/p2v.img
48        qemu-kvm -m 1024 -boot c \
49          -drive file=/var/tmp/p2v.img,if=virtio,index=0 \
50          -drive file=/var/tmp/guest.img,if=virtio,index=1
51
52       where /var/tmp/guest.img would be the disk image of some guest that you
53       want to convert (for testing only).
54

ADDING EXTRA PACKAGES

56       You can install extra packages using the --install option.  This can be
57       useful for making a more fully-featured virt-p2v disk with extra tools
58       for debugging and troubleshooting.  Give a list of packages, separated
59       by commas.  For example:
60
61        virt-p2v-make-disk -o /var/tmp/p2v.img --install tcpdump,traceroute
62

ADDING AN SSH IDENTITY

64       You can inject an SSH identity (private key) file to the image using
65       the --inject-ssh-identity option.
66
67       First create a key pair.  It must have an empty passphrase:
68
69        ssh-keygen -t rsa -N '' -f id_rsa
70
71       This creates a private key ("id_rsa") and a public key ("id_rsa.pub")
72       pair.  The public key should be appended to the "authorized_keys" file
73       on the virt-v2v conversion server (usually to
74       "/root/.ssh/authorized_keys").
75
76       The private key should be injected into the disk image and then
77       discarded:
78
79        virt-p2v-make-disk [...] --inject-ssh-identity id_rsa
80        rm id_rsa
81
82       When booting virt-p2v, specify the URL of the injected file like this:
83
84        │         User name: [root_____________________________] │
85        │                                                        │
86        │          Password: [    <leave this field blank>     ] │
87        │                                                        │
88        │  SSH Identity URL: [file:///var/tmp/id_rsa___________] │
89
90       or if using the kernel command line, add:
91
92        p2v.identity=file:///var/tmp/id_rsa
93
94       For more information, see "SSH IDENTITIES" in virt-p2v(1).

32 BIT VIRT-P2V

97       For improved compatibility with older hardware, virt-p2v-make-disk has
98       an --arch option.  The most useful setting (on x86-64 hosts) is --arch
99       i686, which builds a 32 bit virt-p2v environment that will work on
100       older hardware.  32 bit virt-p2v can convert 64 bit physical machines
101       and can interoperate with 64 bit virt-v2v and 64 bit hypervisors.
102
103       This option requires that you have built virt-p2v.$arch (ie.  usually
104       virt-p2v.i686) by some means, and that you install it next to the
105       ordinary virt-p2v binary (eg. in $libdir/virt-p2v/ or
106       $VIRT_V2V_DATA_DIR).  This is outside the scope of this manual page,
107       but you can find some tips in "BUILDING i686 32 BIT VIRT-P2V" in
108       p2v-building(1).
109

OPTIONS

111       --help
112           Display help.
113
114       --arch ARCH
115           Set the architecture of the virt-p2v ISO.  See "32 BIT VIRT-P2V"
116           above.
117
118           If this option is not supplied, then the default is to use the same
119           architecture as the host that is running virt-p2v-make-disk.
120
121       --inject-ssh-identity id_rsa
122           Add an SSH identity (private key) file into the image.  See "ADDING
123           AN SSH IDENTITY" above.
124
125       --install pkg,pkg,...
126           Add extra packages to the image.  See "ADDING EXTRA PACKAGES"
127           above.
128
129       --no-warn-if-partition
130           Normally you should not write to a partition on a USB drive (ie.
131           don’t use "-o /dev/sdX1", use "-o /dev/sdX" to make a bootable USB
132           drive).  If you do this, virt-builder prints a warning.  This
133           option suppresses that warning.
134
135       -o OUTPUT
136       --output OUTPUT
137           Write output to "OUTPUT", which can be a local file or block
138           device.  The existing contents of the device will be erased.
139
140       -v
141       --verbose
142           Enable verbose output.  Use this if you need to debug problems with
143           the script or if you are filing a bug.
144
145       -V
146       --version
147           Display version number and exit.
148

160           Various data files that are copied into the bootable disk image.
161
162           The location of these files can be changed by setting the

164

ENVIRONMENT VARIABLES

166       "VIRT_P2V_DATA_DIR"
167           The directory where virt-p2v-make-disk looks for data files (see
168           "FILES" above).  If not set, a compiled-in location is used.
