Both virtio-mem and virtio-pmem devices have '.memaddr' attribute
which controls the address where they are mapped in the guest
memory. Ideally, users do not need to specify this as QEMU does
the right thing and computes addresses automatically on startup.
But soon, we will need to record this address as it is part of
guest ABI. And also, there might be some users that want to
control this value. Now, we are in a bit of a pickle, because
both these device types already have a PCI address, therefore we
can't just use <address/> blindly. But what we can do, is
introduce <address/> under the <target/> element. This is also
more conceptual, as knobs under <target/> control guest visible
config of memory device (and .memaddr surely falls into that
category).
NB, SgxEPCDeviceInfo struct in QMP definition also has .memaddr
attribute, but because of the way we build cmd line there's no
(easy) way to set the attribute. So ignore that for now.

When starting QEMU, or when hotplugging a PCI device QEMU might

But despite that, we try to guess. And it more or less works,
until there's a counter example. This time, it's a guest with
both <hostdev/> and an NVMe <disk/>. I've started a simple guest
with 4GiB of memory:
# virsh dominfo fedora
Max memory: 4194304 KiB
Used memory: 4194304 KiB
And here are the amounts of memory that QEMU tried to lock,
obtained via:
grep VmLck /proc/$(pgrep qemu-kvm)/status
1) with just one <hostdev/>
VmLck: 4194308 kB
2) with just one NVMe <disk/>
VmLck: 4328544 kB
3) with one <hostdev/> and one NVMe <disk/>
VmLck: 8522852 kB
Now, what's surprising is case 2) where the locked memory exceeds
the VM memory. It almost resembles VDPA. Therefore, treat is as
such.
Unfortunately, I don't have a box with two or more spare NVMe-s
so I can't tell for sure. But setting limit too tight means QEMU
