We've gotten reports from multiple testers (including Frank Yangjie and myself) that RDMA IPv6 support over RocE (Ethernet) is broken in linux. A patch to Linux is still in review: http://comments.gmane.org/gmane.linux.drivers.rdma/16448 If the user is listening on '[::]', then we will not have a opened a device yet and have no way of verifying if the device is RoCE or not. In this case, the source VM will throw an error for ALL types of connections (both IPv4 and IPv6) if the destination machine does not have a regular infiniband network available for use. The only way to gaurantee that an error is thrown for broken kernels is for the management software to choose a *specific* interface at bind time and validate what time of hardware it is. Unfortunately, this puts the user in a fix: If the source VM connects with an IPv4 address without knowing that the destination has bound to '[::]' the migration will unconditionally fail unless the management software is not explicitly listening on the the IPv4 address while using a RoCE-based device. If the source VM connects with an IPv6 address, then we're OK because we can throw an error on the source (and similarly on the destination). But in mixed environments, this will be broken for a while until it is fixed inside linux. We do provide a *tiny* bit of help in mixed environments, though in this patch: We can list all of the devices in the system and check to see if all the devices are RoCE or Infiniband. If we detect that we have a *pure* RoCE environment, then we can safely thrown an error even if the management sofware has specified '[::]' as the bind address. However, if there is are multiple hetergeneous devices, then we cannot make this assumption and the user just has to be sure they know what they are doing. Signed-off-by: NMichael R.

Commit 6d4cd408 fixed qemu_opts_set_defaults() for an existing corner case, but broke it for another one that can't be reached in current code. Quote from its commit message: I believe [opts_parse()] attempts to do the following: If options don't yet exist, create new options Else, if defaults, modify the existing options Else, if list->merge_lists, modify the existing options Else, fail The only caller that passes true for defaults is qemu_opts_set_defaults(). The commit message then claims: A straightforward call of qemu_opts_create() does exactly that. Wrong. When !list->merge_lists, and the option string doesn't contain id=, and options without ID exist, then we don't actually modify the existing options, we create new ones. Not reachable, because we never pass lists with !list->merge_lists to qemu_opts_set_defaults(). Guard against possible (if unlikely) future misuse with assert().

This is not true, QEMU includes parts that are v2-only. 2) Provide a default for files with no licensing information. 3) It is not just hardware emulation that is under BSD license. 4) Restrict GPLv2-only contributions to user mode emulation (due to code from Linux) and PCI passthrough (due to code from Neocleus). 5) The rules were initially set by Fabrice but are being amended by other people (already in commit ee12e1f3, LICENSE: There is no libqemu.a anymore, 2011-11-15).

While the machine is paused, in guest_phys_blocks_append() we register a one-shot MemoryListener, solely for the initial collection of the valid guest-physical memory ranges that happens at listener registration time. For each range that is reported to guest_phys_blocks_region_add(), we attempt to merge the range with the preceding one. Ranges can only be joined if they are contiguous in both guest-physical address space, and contiguous in host virtual address space. The "maximal" ranges that remain in the end constitute the guest-physical memory map that the dump will be based on.
