[Xen-devel] The related driver and codes of Xen VM disk

[ææå <Chunqi Li> <yzt356@xxxxxxxxx>]

Hi all,

When I set the VM configure file disk=[], I can set VM disk type "file:", "phy:", "tap:aio:", which driver do they use? And where's the related code in Xen Hypervisor?

When I use "file" driver to create a para-virtulized VM, it's OK. But when I replace it to "tap:aio", it will fail. So I want to read the related codes.

Thanks.
