I've been running -current with VMM_DEBUG since Apr 14 and the problem has not reproduced, instead I see spurious stops now. Output in /var/log/messages on the occasion is: Jun 19 03:31:16 golem vmd[95337]: vcpu_run_loop: vm 8 / vcpu 0 run ioctl failed: Invalid argument Jun 19 03:31:16 golem /bsd: vcpu_run_vmx: can't read procbased ctls on exit Jun 19 03:31:17 golem /bsd: vmm_free_vpid: freed VPID/ASID 8 There's also a lot of probably unrelated messages for all the VMs: Jun 19 01:31:10 golem vmd[66318]: vionet_enq_rx: descriptor too small for packet data I realize that this is an old version, so this might be an already fixed bug. I can upgrade to a newer snapshot, but the bug shows about once per month, so by the time it shows it will be an old version again. Kind regards, Thomas
