Hi James,
I'm curious as to how you came to the conclusion that qemu always presents 512 byte sectors?
When using bcache formatted to a 4k sector size, Windows Server 2008 just flat out refuses to install...
This is true regardless of whether I'm passing an LV directly to the DomU (phy), or whether I'm using tap::aio or file.
When formatting the bcache to 512 byte size, Windows tries to install. I say "tries" as then my system kernel
panics and reboots, but that's a bcache issue (I've posted the trace to the bcache list).
Thanks
