I guess I need the list again.

I try to install my first KVM guest. Here is what I do, and finally,
what I stumble on.

First I created a qcow2 img:

# qemu-img create -f qcow2 /var/lib/libvirt/images/test1.img 15G

And I created a network bridge (not essential here)

To get a text-based install, I followed this how-to:

http://sysadminman.net/blog/2011/kvm-virtualization-text-centos-guest-install-2098

My install command was:

virt-install
--name test1
--os-variant=rhel5.4
--ram 512
--vcpus=1
--accelerate
--nographics
-v
--location=/mnt/centos56/
--network bridge:br0
--disk path=/var/lib/libvirt/images/test1.img,size=15
--extra-args="console=ttyS0";

I tried this also without the "size" argument for "disk"

Now, the install begins ok. I do a http install from a nearby mirror.

BUT when it is time to do partitions, I get

> Which drive(s) do you want to use for this installation? |
> |[*] vda 0 MB (Unknown) ^ |
> |

And if I now try to create partitions, I get "no space" error.

What is going on??

Cheers to CentOS!

In my experience, virt-install will create the disk image when passed
a filename via --disk="path=/path/to/nonexistent/disk.dsk,size=15"

In other words, I'd suggest skipping the disk-creation step...

Thanks Paul - it works! I wonder if the disk image will be of type
qcow2. I guess I will soon find out.

Nope. Command "qemu-img info.." tells me that the image type is "raw".
But I don't think I need any of the qcow2 specialties.

Hi Jussi
After installing guest image,
Convert it from raw to qcow2 by "convert" command.

qemu-img convert -f raw disk0.raw -O qcow2 newdisk0.qcow2

Now you can mount newdisk to empty VM with virt-manager.
Or you can edit <DOMAIN>.xml as follows..

/var/lib/libvirt/qemu/<DOMAIN>.xml:

<domain type='kvm'>
<name>vm1</name>
<memory>524288</memory>
<vcpu>1</vcpu>
<os>
<type arch='i686'>hvm</type>
<boot dev='hd'/>
</os>
<on_poweroff>destroy</on_poweroff>
<on_reboot>restart</on_reboot>
<on_crash>restart</on_crash>
<devices>
<emulator>/usr/libexec/qemu-kvm</emulator>
<disk type='file' device='disk'>
<driver name='qemu' type='qcow2'/>
<source file='/home/tsuyoshi/test/newdisk0.qcow2'/>
<target dev='hda' bus='ide'/>
</disk>
<serial type='pty'>
<target port='0'/>
</serial>
<console type='pty'>
<target port='0'/>
</console>
</devices>
</domain>
