KVM: 'ÿ' character after starting a VM via virt-install

I’m unable to start a virtual machine with KVM.

I tried both Centos 5.4 i386 and x86-64 versions.
BIOS virtualization is enabled.

I have installed all necessary rpms (to my knowledge), but as you can see from the output (below), the system does not boot the CD-ROM. It just sits there doing nothing:

virt-install --prompt

Would you like to use KVM acceleration? (yes or no) yes
What is the name of your virtual machine? test

How much RAM should be allocated (in megabytes)? 1024

What would you like to use as the disk (file path)? /var/lib/libvirt/images/test.img
How large would you like the disk (/var/lib/libvirt/images/test.img) to be (in gigabytes)? 20

What is the install CD-ROM/ISO or URL? /root/CentOS-5.4-i386-bin-1of6.iso

Starting install…
Creating storage file… | 20 GB 00:00
Creating domain… | 0 B 00:00

Connected to domain test

Escape character is ^]
ÿ

the ‘ÿ’ character appears after a few seconds, then nothing…

Any help is appreciated!
