I get also bitten by this problem when trying to install ubuntu-15.04-server-amd64.iso in a virtual machine.

If I select LVM the installation hangs when it tries to format /boot as ext2

If I select full disk without LVM the installation hangs when it tries to format / (rootfs) as ext4

I can change to a busy box shell in virtual console 2. Command apport-collect is not in the path.

I checked dmesg but did not see anything bad.

Looking at the output of "ps" shows that the mkfs.ext4 is hanging (status sleeping). Obviously the installer cannot do very much if mkfs.ext4 never completes.

strace does not seem to be available in this environment, so I am a bit out of ideas how to debug where the mkfs.ext4 hangs.
