Thanks. This request was for x86_64 and i386 kernels, rather than
arm64.

I think arm64 Xen support is coming to qemu but it requires real Xen —
while what we're wanting to test here is *emulating* Xen on Linux/KVM,
which isn't something that we support on arm64. So I suspect there's
not a lot of benefit in adding it to the arm64 builds? Vikram, Stefano,
what do you think?

Adding CONFIG_XEN_NETDEV_FRONTEND=y in addition to the above options
would be appreciated too please; we haven't yet made that actually work
in the Xen emulation but we plan to fairly soon.
