diff to v1:
- I've dropped the capability (patch 5/7 in the original set) and am
relying on qemu providing default-ram-id.
I've tested migration from a daemon with these patches to a daemon
without and also vice versa and it worked.
Michal Prívozník (6):
qemuBuildMemoryBackendProps: Move @prealloc setting to backend
agnostic part
qemuBuildMemoryBackendProps: Respect
//memoryBacking/allocation/@mode=immediate
qemuBuildMemoryBackendProps: Prealloc mem for memfd backend
qemuBuildMemoryBackendProps: Fix const correctness
qemu: Track default-ram-id machine attribute
qemu: Use memory-backend-* for regular guest memory

New subject: [PATCH v2 1/6] qemuBuildMemoryBackendProps: Move @prealloc setting to backend agnostic part
All three memory backends (-file, -ram and -memfd) have .prealloc
attribute. Since we are setting it only for -file, the
corresponding code lives only under if() that handles that
specific backend. But in near future we will want to set the
attribute for other backends too. Therefore, move the
corresponding code outside of the if().
This causes some .argv files to be changed, but the only change
happening there is move of the attribute (best viewed with:
'git show --color-words=.').

New subject: [PATCH v2 2/6] qemuBuildMemoryBackendProps: Respect //memoryBacking/allocation/@mode=immediate
If user specifies immediate memory allocation in the domain XML,
they want QEMU to fully allocate its memory. And if the memory
was allocated using plain '-m' then we would honour it. But, if a
memory backend is used, then we don't set the prealloc attribute
of the backend.

New subject: [PATCH v2 3/6] qemuBuildMemoryBackendProps: Prealloc mem for memfd backend
If a domain was using hugepages through memory-backend-file or
via -mem-path, we would turn prealloc on. But we are not doing
that for memory-backend-memfd. Fix this, because we need QEMU to
fully allocate hugepages.

New subject: [PATCH v2 5/6] qemu: Track default-ram-id machine attribute
The machine structure has another (optional) attribute:
default-ram-id, which specifies the alias of the default RAM
object. While the alias is private, it can never change in order
to not break migration. QEMU uses the alias when allocating
regular, not NUMA memory. In order to switch to new command line
and maintain migration, save this ID.

New subject: [PATCH v2 6/6] qemu: Use memory-backend-* for regular guest memory
So far, Libvirt configures memory-backend-* for memory hotplug,
possibly NUMA nodes and in a few other cases. This patch
switches to constructing the memory-backend-* command line for
all cases. To keep ability to migrate guests a little hack is
used: the ID of the object is set to the one that QEMU uses
internally anyways. These IDs are stable (first started to appear
somewhere around v0.13.0-rc0~96) and can't change.
In fact, this patch does exactly what QEMU does internally. The
reason for moving the logic into Libvirt is that QEMU wants to
deprecate the old style of specifying memory.
So far, only x84_64 test cases are changed, because tests for
other architectures use older capabilities, which still lack the
QEMU_CAPS_MACHINE_MEMORY_BACKEND capability and they don't report
the RAM ID.
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1836043

- I've dropped the capability (patch 5/7 in the original set) and am
relying on qemu providing default-ram-id.
I've tested migration from a daemon with these patches to a daemon
without and also vice versa and it worked.
Reviewed-by: Daniel Henrique Barboza <danielhb413(a)gmail.com>
FYI, patch 01 doesn't apply in master after 63af8fdeb2f6. It's a
trivial conflict to solve though (just switch places between
mem-path and prealloc).
Thanks,
DHB
Michal Prívozník (6):
qemuBuildMemoryBackendProps: Move @prealloc setting to backend
agnostic part
qemuBuildMemoryBackendProps: Respect
//memoryBacking/allocation/@mode=immediate
qemuBuildMemoryBackendProps: Prealloc mem for memfd backend
qemuBuildMemoryBackendProps: Fix const correctness
qemu: Track default-ram-id machine attribute
qemu: Use memory-backend-* for regular guest memory
