[libvirt] [PATCH 0/9] qemuxml2argvtest cleanups
by Ján Tomko
While looking at how slow this test has gotten,
I found a lost test case, some redundancies.
Thankfully, not running the HostModel functions
twice helped, but there is still room for improvement:
we spend a lot of time in the CPU driver comparing
the same strings over and over again and with over 300
entries in virQEMUCaps enum, we can reduce some of these
string comparisons in the future to cope with more
and more QEMU versions being tested.
Ján Tomko (9):
tests: drop 'drive' from qemuxml2startup tests
tests: add macro for dealing with exclusive flags
tests: introduce macro for qemu XML->startup XML
tests: only run startup XML tests if requested
tests: report errors in QEMU XML->startup XML tests
tests: drop redundant virQEMUCapsFilterByMachineType
tests: do not mangle real qemu caps in xml2argvtest
tests: turn skipLegacyCPUs into a flag
qemu: remove unnecessary virQEMUCapsFreeHostCPUModel

[libvirt] [PATCH] add nodeset='all' and default for interleave mode
by Peng Hao
For interleave mode,sometimes we want to allocate mmeory regularly
in all nodes on the host. But different hosts has different node number.
So we add nodeset='all' for interleave mode and if nodeset=NULL default
nodeset is 'all' for interleave mode.

[libvirt] [PATCH 0/5] libxl: various migration V3 improvements
by Jim Fehlig
Patch 5 fixes a long standing problem found by some very slow hosts in
xen's osstest
https://lists.xenproject.org/archives/html/xen-devel/2018-08/msg01945.html
While working on the fix, I discovered other problems in libxl's V3
migration protocol. E.g. a modify job on the migrating VM was not
handled properly across the phases on either src or dst host. Patches
1-4 fix this and other problems found along the way.
Jim Fehlig (5):
libxl: migration: defer removing VM until finish phase
libxl: fix logic in P2P migration
libxl: fix job handling across migration phases on src
libxl: fix job handling across migration phases on dst
libxl: join with thread receiving migration data
