I installed a Windows (XP and 2003) guest using one partition as hard drive. I used:
sudo virt-install --connect qemu:///system \ --name win2003-01 \ --ram 1024 \ --keymap=fr \ --disk path=/dev/lvm0/win2003-01 \ --cdrom=/home/mihamina/Windows_2003_Server.iso \ --os-type windows \ --os-variant=win2k3 \ --noapic \ --noacpi \ --network=bridge:br0 \ --accelerate \ --vnc \ --force
And this works fine. Really fine.
The disk section in the definition:
<disk type='block' device='disk'> <source dev='/dev/lvm0/win2003-01'/> <target dev='hda' bus='ide'/> </disk>
After installation, people asked me to add another hard drive to this installation, and then, I added another "disk" in the definition:
<disk type='block' device='disk'> <source dev='/dev/lvm0/win2003-01'/> <target dev='hda' bus='ide'/> </disk> <disk type='block' device='disk'> <source dev='/dev/lvm0/win2003-01-a'/> <target dev='hdb' bus='ide'/> </disk>
I destroyed + undefined + defined + started the VM and the definition is OK (dumpxml), but the Windows guest doesnt see any new hard drive.
I already tried with replacing "ide" with "virtio", no new hard drive yet.

How to make, with this, new hard drive recognized by the Windows guest?
Are you looking for a new driver to appear in 'my computer', because it wouldn't appear there until you format it. Does it show up in device manager?
Misaotra, Thanks, Merci.

Yes, that is what I expected.

I'll try to see in the device manager and see if I can ask for formatting from somewhere. -- Architecte Informatique chez Blueline/Gulfsat: Administration Systeme, Recherche & Developpement +261 34 56 000 19

You could also try partitioning and preformatting the drive before you add it. _Shut down_ the virtual machine, then do: guestfish -a /dev/lvm0/win2003-01-a <<EOF run part-disk /dev/sda mbr mkfs ntfs /dev/sda1 EOF Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones virt-p2v converts physical machines to virtual machines.

I am following this thread for my information want to know is the above syntax of adding a disk to vm definition correct? I have not tried it hence want to know. On Wed, Oct 13, 2010 at 5:55 PM, Richard W.M. Jones <rjones@redhat.com> wrote:

Looks like it. If you get a specific error message, then we can help, otherwise we can't.

I was assuming that the new disk was completely blank, in which case creating a partition table and a filesystem inside that partition might be helpful.
The guy is adding another disk to his vm so why does one need to erase mbr in vm?

OK, I see your confusion. When you add disks to libguestfs, they appear as /dev/sda, /dev/sdb and so on, in the same order that you added them. In this case I added one disk, 'guestfish -a /dev/lvm0/win2003-01-a', which will appear in libguestfs as /dev/sda. This is *not* the same as /dev/sda in a VM.
