This occurs on MIPS and MIPSEL system emulators using the same command line arguments. ARM32, aarch64 and x86_64 emulators don't seem to have this problem. I haven't tested it on any other architectures as I don't have kernel or drive images for them. `qemu-img` seems to work fine with the QCOW2 images used for this test, I was able to create and load offline snapshots from them. The images were created from raw EXT2 filesystem images produced by Buildroot, using `qemu-img convert`. +Steps to reproduce: +1. Start the QEMU system emulator for MIPS/MIPSEL with the given command line. +2. Enter the QEMU monitor with Ctrl-A, C. +3. Run `savevm <vm name>`. +Additional information: +I tried logging what QEMU was doing with the `-D ./log.txt` command line option, but the produced log file was empty. + +If you need me to send you the kernel image files and QCOW2 images used, I would be happy to do so. |
