https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=225629 Nathan Whitehorn <nwhitehorn@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |nwhitehorn@FreeBSD.org --- Comment #11 from Nathan Whitehorn <nwhitehorn@FreeBSD.org> --- Do you see a message like this in your dmesg? WARNING: Running on a broken hypervisor that does not support mandatory H_CLEAR_MOD and H_CLEAR_REF hypercalls. Performance will be suboptimal. If so, could you try enabling those hypercalls in qemu (the kernel supports them on any reasonably recent kernel)? We really need them for the VM system to work and the workaround for older broken kernels/QEMU releases is a bit of hack and may cause memory corruption under load. -- You are receiving this mail because: You are on the CC list for the bug.help
