Yes, ballooning has been a constant source of problems which is why it is disabled in Amazon Linux AMI.
We do not currently support DMA to/from guest physical addresses outside of the E820 map for ENA networking or NVMe storage interfaces. This effectively means that ballooning needs to be disabled, or perhaps some changes would need to be made in the Xen swiotlb code to bounce data that resides in guest physical addresses that are outside of the E820 map. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1668129 Title: Amazon I3 Instance Buffer I/O error on dev nvme0n1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1668129/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
