Hi Reyk & Anton, I upgraded the syzkaller machine from Oct 11 to Oct 21 snapshot and started seeing: Oct 22 10:00:21 ci-openbsd vmd[15707]: qc2_open: missing base image /syzkaller/managers/main/current/image Oct 22 10:00:21 ci-openbsd vmd[15707]: /syzkaller/managers/main/current/image: could not open qc2_open: No such file or directory Oct 22 10:00:21 ci-openbsd vmd[13268]: qc2_open: missing base image /syzkaller/managers/main/current/image Oct 22 10:00:21 ci-openbsd vmd[13268]: /syzkaller/managers/main/current/image: could not open qc2_open: No such file or directory Oct 22 10:00:21 ci-openbsd vmd[51186]: qc2_open: missing base image /syzkaller/managers/main/current/image Oct 22 10:00:21 ci-openbsd vmd[51186]: /syzkaller/managers/main/current/image: could not open qc2_open: No such file or directory
Reverting the change in subject and rebuilding vmd&vmctl stops the problem. The file in question exists: ci-openbsd$ file /syzkaller/managers/main/current/image /syzkaller/managers/main/current/image: QEMU QCOW Image (v3), 1073741824 bytes ci-openbsd$ ls -l /syzkaller/managers/main/current/image -rw-r----- 2 syzkaller syzkaller 545783808 Oct 22 10:34 /syzkaller/managers/main/current/image Under the hood this command line is executed: vmctl start ci-openbsd-main-0 -b /syzkaller/managers/main/current/kernel -d /syzkaller/managers/main/workdir/instance-0/disk.qcow2 -m 512M -L -c -t syzkaller Anton, what does your code is syzkaller do to create this file? -rw------- 1 syzkaller syzkaller 262144 Oct 22 10:59 /syzkaller/managers/main/workdir/instance-0/disk.qcow2 The file does reference the base image: ci-openbsd$ strings /syzkaller/managers/main/workdir/instance-0/disk.qcow2 h/syzkaller/managers/main/current/image Thanks Greg -- nest.cx is Gmail hosted, use PGP for anything private.
