No.

I get another error, wherein Linux kernel does boot but up to
initializing the SWIOTLB, and then it crashes due to Xen not allowing
SWIOTLB to swizzle the pages. This is what Xen says:
(XEN) mm.c:3847:d10 Bad page 00000000001beab4: ed=ffff830151210000(10),
sd=ffff830151210000, caf=8000000000000002, taf=7400000000000001
Also experienced by another user:

Haven't dug deeper in the hypervisor to figure out the caf/taf business.
