Attempting to start a VM results in this error:

Error starting domain: internal error: qemu unexpectedly closed the monitor:2018-11-22T11:13:56.341729Z qemu-system-x86_64:cannot set up guest memory 'pc.ram': Cannot allocate memory

Traceback (most recent call last):
File "/usr/share/virt-manager/virtManager/asyncjob.py", line 89, in cb_wrapper
  callback(asyncjob, *args, **kwargs)
File "/usr/share/virt-manager/virtManager/asyncjob.py", line 125, in tmpcb
  callback(*args, **kwargs)


Same result two times.  VM starts correctly with 4.19.2-towo.2-siduction-amd64.

That has nothing to do with the kernel, that are pyton errors.
You have seen, there is an ongoing python transition?

And btw, errors from virt-manager have also nothing to do with the function of qemu.

OK, yes I have seen the python transition.  But how is the VM running correctly with 4.19.2, and failing on 4.19.3?

How much host ram?
Does it work after

echo 3 |  tee /proc/sys/vm/drop_caches

??

If not, try the new kernel (towo.2), which is 4.19.4-rc1.
Mabe it was a kernel regression, since that rc was released shortly after the release of 4.19.3.

This problem does not occur with kernel 4.19.4-towo-1 -- apparently there was a regression. Marking "Solved".
