Hey guys, I got another "reboot crash" with gfapi and this time libvirt-3.2.1 (from cbs.centos.org). Is there anyone who can audit the libgfapi usage in libvirt? :-) WK: I use bonded 2x10Gbps and I do get crashes only in heavy I/O situations (fio). Upgrading system (apt-get dist-upgrade) was ok, so this might be even related to amount of IOPS. -ps On Sun, Sep 10, 2017 at 6:37 AM, WK <wkmail@xxxxxxxxx> wrote: > I'm on 3.10.5.
