[v3] PCI devices passthrough on Arm, part 2

[PATCH v3 07/11] libxl: Allow removing PCI devices for all types of domains

Posted by Oleksandr Andrushchenko 3 years, 2 months ago

From: Oleksandr Andrushchenko <oleksandr_andrushchenko@epam.com>

The PCI device remove path may now be used by PVH on ARM, so the
assert is no longer valid.
