Nested KVM issue
Both baremetal and compute ? Are there any other metrics do you consider useful
to collect for troubleshooting purposes ?

Running the compute node for several days simply triggers it.

I would attempt to decrease number of VCPUS allocated to cloud VMs.
Say try 4 => 2 . My guess there
s soon as the problem
reproduces again (in about 2 days) but for now there are more than 80 GB

Note that a reboot of the compute node doesn't fix the problem. Only a shutdown
of the compute and a virsh start on it works.
