Aren't we still in need of SR-IOV support in order to make such an unconditional statement? Jan

PCI passthrough is already supported for HVM domUs when dom0 is PVH on x86. The last related patch on Qemu side was merged after Xen4.20 release. So mention this feature in Xen4.21 entry. Signed-off-by: Jiqian Chen <Jiqian.Chen@amd.com> --- CHANGELOG.md | 1 + 1 file changed, 1 insertion(+)
