[libvirt] [PATCH v3] qemu: rename migration APIs to include Src or Dst in their name
by Daniel P. Berrangé 19 Feb '18

19 Feb '18

It is very difficult while reading the migration code trying to understand whether a particular function is being called on the src side or the dst side, or either. Putting "Src" or "Dst" in the method names will make this much more obvious. "Any" is used in a few helpers which can be called from both sides. Signed-off-by: Daniel P.

[libvirt] [PATCH] conf: move 'generated' member from virMacAddr to virDomainNetDef
by Laine Stump 19 Feb '18

19 Feb '18

Commit 7e62c4cd26d (first appearing in libvirt-3.9.0 as a resolution to rhbz #1343919) added a "generated" attribute to virMacAddr that was set whenever a mac address was auto-generated by libvirt. This knowledge was used in a single place - when trying to match a NetDef from the domain to delete with user-provided XML. Since the XML parser always auto-generates a MAC address for NetDefs when none is provided, it was previously impossible to make a search where the MAC address wasn't significant, but the addition of the "generated" attribute made it possible for the search function to ignore auto-generated MACs. This implementation had a problem though - it was adding a field to a "low level" struct - virMacAddr - which is used in other places with the assumption that it contains exactly a 6 byte MAC address and nothing else. In particular, virNWFilterSnoopEthHdr uses virMacAddr as part of the definition of an ethernet packet header, whose layout must of course match an actual ethernet packet. Adding the extra bools into virNWFilterSnoopEthHdr caused the nwfilter driver's "IP discovery via DHCP packet snooping" functionality to mysteriously stop working. In order to fix that behavior, and prevent potential future similar odd behavior, this patch moves the "generated" member out of virMacAddr (so that it is again really just a MAC address) and into virDomainNetDef, and sets it only when virDomainNetGenerateMAC() is called from virDomainNetDefParseXML() (which is the only time we care about it).

One way to avoid the problem is to have <shareable/> in disk definition so that libvirt doesn't restore disk labels.

Unfortunately, the patches were abandoned and the issue is even worse. I remember having a discussion on this topic lately (although can't recall where). Turns out, we firstly relabel the disks and only after that we try to obtain disk locks. So if the latter fails (e.g. because another domain holds the locks) the lables are changed anyway. The suggested solution was to have two locks: one for disk contents the other for disk metadata (like security labels). Anyway, I don't think there's anybody working on this actively. Sorry. Michal
