Hi all,
I am occasionally seeing a kernel warning when running virtual machines
in Hyper-V, which usually happens a minute or so after boot. It does not
happen on every boot and it is reproducible on at least v5.10. I think
it might have something to do with constant reboots, which I do when
testing various kernels.
The stack trace is as follows:
[ 49.215291] kworker/0:1: vmemmap alloc failure: order:9, mode:0x4cc0(GFP_KERNEL|__GFP_RETRY_MAYFAIL), nodemask=(null),cpuset=/,mems_allowed=0

Is this a known issue and/or am I doing something wrong? I only noticed
this because there are times when I am compiling something intensive in
the VM such as LLVM and the VM runs out of memory even though I have
plenty of free memory on the host but I am not sure if this warning is
related to that issue.
I do not have much experience with Hyper-V so it is possible I do not
have something configured properly or there is some other issue going
on. Let me know if there is any further information I can provide or
help debug in any way.
Cheers,

Apart from order:9 (mm Cced), events_unbound is the right workqueue instead
because the report shows the risk that hot_add_req could block other pending
events longer than thought. Any special reason for the events wq?

I had one of these events just happen, journalctl output attached. I
have no idea what the "unhandled message: type:" messages mean, I guess
that corresponds to the switch statement in balloon_onchannelcallback().

Hi,
Is hotplugged memory getting onlined automatically (either from user
space via a udev script or via the kernel, for example, with
CONFIG_MEMORY_HOTPLUG_DEFAULT_ONLINE)?
If it's not getting onlined, you easily sport after hotplug e.g., via
"lsmem" that there are quite some offline memory blocks.
Note that x86_64 code will fallback from populating huge pages to
populating base pages for the vmemmap; this can happen easily when under
memory pressure.
If adding memory would fail completely, you'd see another "hot_add
memory failed error is ..." error message from hyper-v in the kernel
log. If that doesn't show up, it's simply suboptimal, but hotplugging
memory still succeeded.
Note: we could support "memmap_on_memory" in some cases (e.g., no memory
holes in hotadded range) when hotplugging memory blocks via hyper-v,
which would result in this warning less trigger less frequently.

It does look like this kernel configuration has

Not sure if it is relevant or not but this warning can show up within a
minute of startup without me doing anything in particular.

I did notice that from the code in hv_balloon.c but I do not think I
have ever seen that message in my logs.

Okay, so then it's most likely really more of an issue with fragmented
physical memory -- which is suboptimal but not a show blocker in your setup.
(there are still cases where memory onlining can fail, especially with
kasan running, but these are rather corner cases)

I remember that Hyper-V will start with a certain (configured) boot VM
memory size and once the guest is up and running, use memory stats of
the guest to decide whether to add (hotplug) or remove (balloon inflate)
memory from the VM.
So this could just be Hyper-V trying to apply its heuristics.

Okay, so at least hotplugging memory is working.

Could you clarify if your VM is running in the context of the Windows
Subsystem for Linux (WSL) v2 feature in Windows 10? Or are you
running a "traditional" VM created using the Hyper-V Manager UI
or Powershell?
If the latter, how do you have the memory configuration set up? In
the UI, first you can specify the RAM allocated to the VM. Then
separately, you can enable the "Dynamic Memory" feature, in which
case you also specify a "Minimum RAM" and "Maximum RAM". It
looks like you must have the "Dynamic Memory" feature enabled
since the original stack trace includes the hot_add_req() function
from the hv_balloon driver.
The Dynamic Memory feature is generally used only when you
need to allow Hyper-V to manage the allocation of physical memory
across multiple VMs. Dynamic Memory is essentially Hyper-V's way of
allowing memory overcommit. If you don't need that capability,
turning off Dynamic Memory and just specifying the amount of
memory you want to assign to the VM is the best course of action.
With Dynamic Memory enabled, you may have encountered a
situation where the memory needs of the VM grew very quickly,
and Hyper-V balloon driver got into a situation where it needed
to allocate memory in order to add memory, and it couldn't. If
you want to continue to use the Dynamic Memory feature, then
you probably need to increase the initial amount of RAM assigned
to the VM (the "RAM" setting in the Hyper-V Manager UI).

This is a traditional VM created using the Hyper-V Manager.

That is correct. I believe Dynamic Memory is the default setting so I
just left that as it was. The startup memory for this virtual machine is
2GB as it is a lightweight Arch Linux Xfce4 configuration and aside from
occasionally compiling software, it will just be sitting there because
it is mainly there for testing kernels.

Ack. My workstation was occasionally memory constrained so I figured
relying on the Dynamic Memory feature would make sense. I upgraded the
amount of RAM that I had today so I will probably just end up disabling
the Dynamic Memory feature and allocating the amount of memory up front.

I will keep that in mind and see if I can find a good number.
Thanks for the reply!
