Re: [PATCH] libxl: virtio-blk-pci support for FV domain

[Takeshi HASEGAWA <hasegaw@gmail.com>]

My patch threats virtio block devices with same manner with xvd, sd, and hd.
Though, I need to discuss with xen developpers whether the vbd number
assignment is reasonable or not.

I guess blktap and blkback will never handle virto block device, so assigning
(reserving) the whole range of 2 << 28 for virtio block vbd may be more better.

Actually virtio is not Xen's VBD, so vbd number is not mandatory to work.
However, I believe this approach makes virtio block manageable
in same way as xvd and others.

I am looking forward for xen developpers' opinions.


Thanks,
Takeshi
