Hi Alex,

Since the address space of relocated Xen is in the same region with identity mapping address space.

There may be conflict.

Can we put Xen as other region?

Yes, the new mapping could be: 0xf000000000000000: WB identify mapped 0xf200000000000000: UC identify mapped 0xf400000000000000: xen + default sharedinfo + percpu 0xf600000000000000: virt frame table

IIRC I tested such a map while I was testing xen relocation.

Tristan.
