This was not happening with qemu-4.2 (on Ubuntu 20.04). This is also not happening when using accel=kvm instead. The issue has been first noticed on Debian 11 (Bullseye) with the versions above, but it is happening in the same way on Centos 8 Stream, Ubuntu 21.10 and a pre-release version of Ubuntu 22.04. It also also seen when testing with qemu-6.1 built from source. -Steps to reproduce: -1. Deploy devstack (https://opendev.org/openstack/devstack) with VIRT_TYPE=qemu on a VM -2. Start an instance with cirros image and a flavor allocating 256MB -3. Do a ps and see a RSS size of about 512MB being used after the instance has finished booting -4. Expected result (seen with qemu-4.2 or VIRT_TYPE=kvm): RSS stays < 256MB -Additional information: -I can try to find a smaller commandline for manual reproduction if needed. The above sample is generated by OpenStack Nova via libvirt. |
