Hi Richard,
Thanks a lot for your prompt response. I am enumerating the steps that I
followed during the provisioning, if it helps.
Thanks ...
1. These are the commands that I used to create the disk image.
qemu-img create -f qcow2 base_VM.qcow2 512M
kvm -m 512 -cdrom Core-current.iso -hda base_VM.qcow2 -boot d -net
nic,macaddr=00:00:00:00:cc:10 -net
tap,script=/etc/ovs-ifup0,downscript=/etc/ovs-ifdown0
2. a) The output of qemu-img
qemu-img info base_VM.qcow2
image: images/base_VM.qcow2
file format: qcow2
virtual size: 512M (536870912 bytes)
disk size: 46M
cluster_size: 65536
2. b) virt-filesystems --all --long -h -a base_VM.qcow2
Name Type VFS Label MBR Size Parent
/dev/sda1 filesystem ext4 - - 512M -
/dev/sda1 partition - - 83 512M /dev/sda
/dev/sda device - - - 512M -
In my previous analysis I didn't see that TCL actually installs itself
to a persistent disk. As shown above and in your trace, it's creating
an ext4 partition on the persistent disk.
I installed TCL to a disk to see what happens.
$ guestfish --ro -a tcl.qcow2

It's still using an initramfs, so it's unlikely we can make inspection
show the real TCL filesystem. But we should certainly be able to
improve on current behaviour (ie fix RHBZ#1079734).
