I tested F20 on a physical host with a vertex3 ssd. But it was not a requested test case, i re-used a md raid0 with a 6gb partition of the ssd. The file-system was setup as a storage pool for virt-manager. I did not experience any issues, i installed 2 F20 guest at the same time. I even rebooted many times and it survived several kernel updates. I did not test a power-loss scenario. I has been working ok since a couple of days. I also did the non lvm tests on guest, without any issue.
Thanks for your feedback, glad to hear it works well for you.
The only thing that i can recall as strange is the fact that bcache seems to not to use discard/trim for some reason.
discard/trim can be enabled, see: http://evilpiepirate.org/git/linux-bcache.git/tree/Documentation/bcache.txt?h=bcache-dev#n126 There's also an explanation in the document why it isn't enabled by default: "|Defaults to off, since SATA TRIM is an unqueued command (and thus slow)."
