Nice! Did you also implement the xm/xend side of resizing?
My goal was to not have the end-user do anything other than what
was minimally required to resizing the device on the host side.
Once the device is resized on the host side, this capacity change
is propagated to the guest without having to invoke any xm command.
Oh, even better!
What version of the kernel did you test with? 2.6.27?
I tested this on 2.6.32. The patches should apply to earlier kernels without
too much trouble.
Jeremy: Hopefully you can add this patch to your tree.
It applied fairly cleanly, but I haven't tested it yet. Ky, by 2.6.32 I
assume I mean your one, not pvops? (Because your patch is touching
blkfront in the wrong place.)
Yes. This patch was against our sles11 sp1.
What happens if the frontend doesn't support the resize, and the device
shrinks? Will the backend just raise IO errors for out of range requests?
