[CentOS] C6 VM text install not recognizing LV

Hi,

I am trying to install a C6 VM on C6 using the text installer using:

# virt-install -n C6_1 -r 3072 --os-variant=rhel6 -l \
ftp://ftp.nluug.nl/site/centos.org/CentOS/6.3/os/x86_64/ --disk \
path=/dev/VG1/vm_c6_1 -w network:default --nographics \
-x "console=ttyS0" --autostart

/dev/VG1/vm_c6_1 has been successfully created. The installation starts
but once I get to the disk partitioning no disk is listed and I cannot
continue the installation.

Even worse, if I press space on the empty list CPU usage goes up to 100%
for the qemu-kvm process.

ps shows

Any ideas why anaconda isn't picking up the LV? Could this be a CentOS
specific patch to anaconda or is that unlikely?

Thanks for any input,
Leonard.
