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

152           image.
153
154           The location of the binary can be changed by setting the

159       $datadir/virt-p2v/p2v.service
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
163           "VIRT_P2V_DATA_DIR" environment variable.
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.
