Hello community,
--
I am operating an openstack cluster where applications (libvirt/nova etc) are running using containers. The compute node's arch is aarch64 (phytium 2500), when there are virtual machines around 60 or 70, I failed to boot new virtual machines and faced with following error message,
error: internal error: qemu unexpectedly closed the monitor: 2022-10-24T06:23:54.545685Z qemu-system-aarch64: -sandbox on,obsolete=deny,elevateprivileges=deny,spawn=deny,resourcecontrol=deny: failed to load seccomp syscall filter in kernel: Operation canceled
Interestingly, if I virsh stop one virtual machine, I am able to boot another. Besides, I managed to manually boot a virtual machine without any issue. So my question is what could be the potential cause of this behavior and how can I deal with it? Thank you very much in advance for the help.
Best Regards,
Jiatong Shen
