This commit is released with QEMU 6.1, so if we try to migrate a VM where the host kernel supports SEQPACKET but machine type version is less than 6.1, we get the following errors: Features 0x130000002 unsupported. Allowed features: 0x179000000 Failed to load virtio-vhost_vsock:virtio error while loading state for instance 0x0 of device '0000:00:05.0/virtio-vhost_vsock' load of migration failed: Operation not permitted Let's disable the feature bit for machine types < 6.1. We add a new OnOffAuto property for this, called `seqpacket`. When it is `auto` (default), QEMU behaves as before, trying to enable the feature, when it is `on` QEMU will fail if the backend (vhost-vsock kernel module) doesn't support it.

It starts at address 0x0cc4 and ends at 0x0cdb. At the time when the patch was written but the final version of the patch was not yet pushed upstream, this address range was free and did not conflict with any other IO address ranges. However, with the following change, this address range was no longer conflict free as in this change, the IO address range (value of ACPI_PCIHP_SIZE) was incremented by four bytes: b32bd763a1ca92 ("pci: introduce acpi-index property for PCI device") This can be seen from the output of QMP command 'info mtree' : 0000000000000600-0000000000000603 (prio 0, i/o): acpi-evt 0000000000000604-0000000000000605 (prio 0, i/o): acpi-cnt 0000000000000608-000000000000060b (prio 0, i/o): acpi-tmr 0000000000000620-000000000000062f (prio 0, i/o): acpi-gpe0 0000000000000630-0000000000000637 (prio 0, i/o): acpi-smi 0000000000000cc4-0000000000000cdb (prio 0, i/o): acpi-pci-hotplug 0000000000000cd8-0000000000000ce3 (prio 0, i/o): acpi-cpu-hotplug It shows that there is a region of conflict between IO regions of acpi pci hotplug and acpi cpu hotplug. Unfortunately, the change caf108bc58790 did not update the IO address range appropriately before it was pushed upstream to accommodate the increased length of the IO address space introduced in change b32bd763a1ca92. Due to this bug, windows guests complain 'This device cannot find enough free resources it can use' in the device manager panel for extended IO buses. This issue also breaks the correct functioning of pci hotplug as the following shows that the IO space for pci hotplug has been truncated: (qemu) info mtree -f FlatView #0 AS "I/O", root: io Root memory region: io 0000000000000cc4-0000000000000cd7 (prio 0, i/o): acpi-pci-hotplug 0000000000000cd8-0000000000000cf7 (prio 0, i/o): acpi-cpu-hotplug Therefore, in this fix, we adjust the IO address range for the acpi pci hotplug so that it does not conflict with cpu hotplug and there is no truncation of IO spaces. The starting IO address of PCI hotplug region has been decremented by four bytes in order to accommodate four byte increment in the IO address space introduced by change b32bd763a1ca92 ("pci: introduce acpi-index property for PCI device") After fixing, the following are the corrected IO ranges: 0000000000000600-0000000000000603 (prio 0, i/o): acpi-evt 0000000000000604-0000000000000605 (prio 0, i/o): acpi-cnt 0000000000000608-000000000000060b (prio 0, i/o): acpi-tmr 0000000000000620-000000000000062f (prio 0, i/o): acpi-gpe0 0000000000000630-0000000000000637 (prio 0, i/o): acpi-smi 0000000000000cc0-0000000000000cd7 (prio 0, i/o): acpi-pci-hotplug 0000000000000cd8-0000000000000ce3 (prio 0, i/o): acpi-cpu-hotplug This change has been tested using a Windows Server 2019 guest VM. Windows no longer complains after this change.

When we have a machine type that enables page poison, and the guest enables it (which needs a new kernel), things fail rather unpredictably. The fallout from this is that most of the other subsections fail to load, including things like the feature bits in the device, one possible fallout is that the physical addresses of the queues then get aligned differently and we fail with an error about last_avail_idx being wrong. It's not obvious to me why this doesn't produce a more obvious failure, but virtio's vmstate loading is a bit open-coded.
