When we spawn a VM (regular ubuntu 1804.4) with 16 CPU cores and 8G memory and a VPP backed interface, our VPP instance dies: Dec 02 13:39:39 compute03-asd002a vpp[1788161]: /usr/bin/vpp[1788161]: linux_epoll_file_update:120: epoll_ctl: Operation not permitted (errno 1) Dec 02 13:39:39 compute03-asd002a /usr/bin/vpp[1788161]: linux_epoll_file_update:120: epoll_ctl: Operation not permitted (errno 1) Dec 02 13:39:39 compute03-asd002a vpp[1788161]: /usr/bin/vpp[1788161]: received signal SIGSEGV, PC 0x7fdf80653188, faulting address 0x7ffe414b8680 Dec 02 13:39:39 compute03-asd002a /usr/bin/vpp[1788161]: received signal SIGSEGV, PC 0x7fdf80653188, faulting address 0x7ffe414b8680 Dec 02 13:39:39 compute03-asd002a vpp[1788161]: /usr/bin/vpp[1788161]: #0 0x00007fdf806556d5 0x7fdf806556d5 Dec 02 13:39:39 compute03-asd002a /usr/bin/vpp[1788161]: #0 0x00007fdf806556d5 0x7fdf806556d5 Dec 02 13:39:39 compute03-asd002a /usr/bin/vpp[1788161]: #1 0x00007fdf7feab8a0 0x7fdf7feab8a0 Dec 02 13:39:39 compute03-asd002a vpp[1788161]: /usr/bin/vpp[1788161]: #1 0x00007fdf7feab8a0 0x7fdf7feab8a0 Dec 02 13:39:39 compute03-asd002a vpp[1788161]: /usr/bin/vpp[1788161]: #2 0x00007fdf80653188 0x7fdf80653188 Dec 02 13:39:39 compute03-asd002a /usr/bin/vpp[1788161]: #2 0x00007fdf80653188 0x7fdf80653188 Dec 02 13:39:39 compute03-asd002a /usr/bin/vpp[1788161]: #3 0x00007fdf81f29e52 0x7fdf81f29e52 Dec 02 13:39:39 compute03-asd002a vpp[1788161]: /usr/bin/vpp[1788161]: #3 0x00007fdf81f29e52 0x7fdf81f29e52 Dec 02 13:39:39 compute03-asd002a vpp[1788161]: /usr/bin/vpp[1788161]: #4 0x00007fdf80653b79 0x7fdf80653b79 Dec 02 13:39:39 compute03-asd002a /usr/bin/vpp[1788161]: #4 0x00007fdf80653b79 0x7fdf80653b79 Dec 02 13:39:39 compute03-asd002a vpp[1788161]: /usr/bin/vpp[1788161]: #5 0x00007fdf805f1bdb 0x7fdf805f1bdb Dec 02 13:39:39 compute03-asd002a /usr/bin/vpp[1788161]: #5 0x00007fdf805f1bdb 0x7fdf805f1bdb Dec 02 13:39:39 compute03-asd002a vpp[1788161]: /usr/bin/vpp[1788161]: #6 0x00007fdf805f18c0 0x7fdf805f18c0 Dec 02 13:39:39 compute03-asd002a vpp[1788161]: /usr/bin/vpp[1788161]: #7 0x00007fdf80655076 0x7fdf80655076 Dec 02 13:39:39 compute03-asd002a /usr/bin/vpp[1788161]: #6 0x00007fdf805f18c0 0x7fdf805f18c0 Dec 02 13:39:39 compute03-asd002a vpp[1788161]: /usr/bin/vpp[1788161]: #8 0x00007fdf7fa3b3f4 0x7fdf7fa3b3f4 Dec 02 13:39:39 compute03-asd002a /usr/bin/vpp[1788161]: #7 0x00007fdf80655076 0x7fdf80655076 Dec 02 13:39:39 compute03-asd002a /usr/bin/vpp[1788161]: #8 0x00007fdf7fa3b3f4 0x7fdf7fa3b3f4 Dec 02 13:39:39 compute03-asd002a systemd[1]: vpp.service: Main process exited, code=dumped, status=6/ABRT Dec 02 13:39:39 compute03-asd002a systemd[1]: vpp.service: Failed with result 'core-dump'. While we are able to run 8 core VMs, we’d like to be able to create beefier. VPP restarts, but never makes it to create the vhost-user interface.. Anyone ran into the same issue? Regards, Eyle
