F12: How to add VM with virt-manager?

[sean darcy]

I have a qcow Windows 7 image created from VBox with qemu-img.

VBoxManage clonehd --format RAW Windows-7-32bit-copy.vdi
Windows-7-32bit-raw.img
VirtualBox Command Line Management Interface Version 3.1.2
(C) 2005-2009 Sun Microsystems, Inc.
All rights reserved.

0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%
Clone hard disk created in format 'RAW'. UUID:
45b51467-5b5f-491b-bfbb-14d9a61cd503

Then:

qemu-img convert -O qcow2 Windows-7-32bit-raw.img Windows-7-32bit.qcow
qemu-img info Windows-7-32bit.qcow
image: Windows-7-32bit.qcow
file format: qcow2
virtual size: 20G (21474836480 bytes)
disk size: 18G
cluster_size: 65536


I've got qemu/kvm installed an F12 machine.

With virt-manager the dialog to install Create a new VM only allows
DVD, iso, ftp, etc. Not a local .qcow image.

I tried restore saved machine and got:

image magic is incorrect

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/manager.py", line 652, in
restore_saved_callback
    newconn.restore(file_to_load)
  File "/usr/share/virt-manager/virtManager/connection.py", line 657, in
restore
    self.vmm.restore(frm)
  File "/usr/lib64/python2.6/site-packages/libvirt.py", line 1420, in restore
    if ret == -1: raise libvirtError ('virDomainRestore() failed', conn=self)
libvirtError: operation failed: image magic is incorrect

So how do I add this image to kvm?

I always just give it some random iso to make it happy, and
then when it asks about disk image, use the pick existing
disk option and browse local to point at the image.

Once it starts booting to do the "install", I just use force off,
make sure the random iso image I gave it is no longer mounted,
then boot from the disk.

For what it is worth, there is a RFE to support import of existing disk
images in virt-manager - Fedora bug #542829 [1].

There is also virt-install's --import option if you were not aware of
it.

Hope that helps,

Paul
