qemu_hotplug: Temporarily allow emulator thread to access other NUMA nodes during mem hotplug
Again, this fixes the same problem as one of previous commits,
but this time for memory hotplug. Long story short, if there's a
domain running and the emulator thread is restricted to a subset
of host NUMA nodes, but the memory that's about to be hotplugged
requires memory from a host NUMA node that's not in the set we
need to allow emulator thread to access the node, temporarily.
Signed-off-by: Michal Privoznik <mprivozn@redhat.com> Reviewed-by: Martin Kletzander <mkletzan@redhat.com>
What this means is the emulator thread is pinned onto host NUMA
node #0 (by setting corresponding cpuset.mems to "0"), and two
memory-backend-* objects are created:
Note, the emulator thread is pinned well before QEMU is even
exec()-ed.
Now, the way memory allocation works in QEMU is: the emulator
thread calls mmap() followed by mbind() (which is sane, that's
how everybody should do it). BUT, because the thread is already
restricted by CGroups to just NUMA node #0, calling:
mbind(host-nodes:[1]); /* made up syntax (TM) */
fails. This is expected though. Kernel was instructed to place
the memory at NUMA node "0" and yet, process is trying to place
it elsewhere.
We used to solve this by not restricting emulator thread at all
initially, and only after it's done initializing (i.e. we got the
QMP greeting) we placed it onto desired nodes. But this had its
own problems (e.g. QEMU might have locked pieces of its memory
which were then unable to migrate onto different NUMA nodes).
Therefore, in v5.1.0-rc1~282 we've changed this and set cgroups
upfront (even before exec()-ing QEMU). And this used to work, but
something has changed (I can't really put my finger on it).
Therefore, for the initialization start the thread with union of
all configured host NUMA nodes ("0-1" in our example) and fix the
placement only after QEMU is started.
NB, the memory hotplug suffers the same problem, but that will
be fixed in the next commit.

qemu_domin: Account for NVMe disks when calculating memlock limit on hotplug
During hotplug of a NVMe disk we need to adjust the memlock
limit. The computation of the limit is handled by
qemuDomainGetMemLockLimitBytes() which looks at given domain
definition and accounts for various device types (as different
types require different amounts). But during disk hotplug the
disk is not added to domain definition until the very last
moment. Therefore, qemuDomainGetMemLockLimitBytes() has this
@forceVFIO argument which tells it to assume VFIO even if there
are no signs of VFIO in domain definition. And this kind of
works, until the amount needed for NVMe disks changed (in
v9.3.0-rc1~52). What's missing in the commit is making @forceVFIO
behave the same as if there was an NVMe disk present in the
domain definition.
But, we can do even better - just mimic whatever we're doing for
hostdevs. IOW - introduce qemuDomainAdjustMaxMemLockNVMe() that
behaves the same as qemuDomainAdjustMaxMemLockHostdev().
There are subtle differences though:
1) qemuDomainAdjustMaxMemLockHostdev() can afford placing hostdev
right at the end of vm->def->hostdevs, because the array was
already reallocated (at the beginning of
qemuDomainAttachHostPCIDevice()). But
qemuDomainAdjustMaxMemLockNVMe() doesn't have that luxury.
2) qemuDomainAdjustMaxMemLockHostdev() places a
virDomainHostdevDef pointer into domain definition, while
qemuDomainStorageSourceAccessModifyNVMe() (which calls
qemuDomainAdjustMaxMemLock()) sees a virStorageSource pointer
but domain definition contains virDomainDiskDef. But that's
okay, we can create a dummy disk definition and append it into
the domain definition.
After this, qemuDomainAdjustMaxMemLock() can be called with
@forceVFIO = false, as the disk is now part of domain definition
(when computing the new limit).
