I'm trying to create a 6.5 VM on a 6.5 system using virt-install...
# virt-install --network bridge:br0 --name kfat --ram=2048 --vcpus=2 --disk path=/var/lib/libvirt/images/kfat.img,size= 16 --cdrom=/home/downloads/CentOS-6.5-x86_64-minimal.iso
I get through the first part of the installation, asks for disk layout (I leave default, tell it to take the whole vdisk), networking (I setup a static IP), then bombs with an error that it can't mount /
not sure what to do next.

to be more specific. it gets all the way through the formatting the disk thing like a normal install, then I get a popup...

I had this exact problem a while back and I am racking my brains as to what I did to fix it.

in my case,
# virt-install --network bridge:br0 --name kfat --ram=2048 --vcpus=2 \ --disk path=/var/lib/libvirt/images/kfat.img,size=16,cache=writeback \ --cdrom=/home/downloads/CentOS-6.5-x86_64-minimal.iso
worked.
the 'cache=writeback' fixed it, the fundamental problem was, /var/lib/libvirt/images is XFS on a SSD so is using 4096 byte sectors, and kvm has an impedance mismatch with that.

the backing store is a Crucial M550 SSD, formatted XFS. does that have somethign to do with this?
and... ok, found something suggesting cache=writeback, but it didn't quite explain, https://bugzilla.redhat.com/show_bug.cgi?id=997839
after thinking about it, looking at the options, I added that to the --disk option of virt-install, and now installing packages,
