Yes, that might be possible. A couple of suggestions to narrow it down further: - try to reproduce with 2 or 4 vcpus (3 cpus is probably not a well tested configuration) - try to reproduce with the ahci-hd device emulation instead of virtio-blk. If this problem is reproducible then I am happy to work with you to get to the bottom of this. best Neel > -- > Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 > p...@freebsd.org | TCP/IP since RFC 956 > FreeBSD committer | BSD since 4.3-tahoe > Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ freebsd-virtualization@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "freebsd-virtualization-unsubscr...@freebsd.org"
