https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D276575 --- Comment #1 from Duncan <dpy@pobox.com> --- Apologies, adding the attachment posted the first comment. I can't seem to = be able to edit it, so this is an addition. Host is 128GB Intel(R) Xeon(R) CPU E5-1650 v4 @ 3.60GHz (6 core). I have attached the minidump from the windows vm crashing itself due to continuous high diskIO. As I mentioned the case of a high disk load (reads) on the host resulting i= n a corrupted disk image (due to the disk unexpectedly disappearing from window= s) is more worrying for me. I have reverted all my VMs back to virtIO-blk. On the weekend I will shutdown the vm, snapshot, change back to nvme, turn = on debug and try some more scenarios. Any suggestions would be welcome. The vm-bhyve config file is as follows (both guests have the same setup): #--------------------------------------------- loader=3D"uefi" bhyve_options=3D"-A" graphics=3D"yes" graphics_res=3D"1600x900" graphics_port=3D"5915" vnc_password=3D"########" xhci_mouse=3D"yes" cpu_sockets=3D1 cpu_cores=3D5 cpu=3D5 wired_memory=3D"yes" memory=3D20G #debug=3D"yes" # put up to 8 disks on a single ahci controller. # without this, adding a disk pushes the following network devices onto hig= her slot numbers, # which causes windows to see them as a new interface ahci_device_limit=3D"8" # ideally this should be changed to virtio-net and drivers installed in the guest # e1000 works out-of-the-box #network0_type=3D"e1000" network0_type=3D"virtio-net" network0_switch=3D"lan" #disk0_type=3D"nvme" disk0_type=3D"virtio-blk" disk0_name=3D"disk0.img" #disk1_type=3D"nvme" disk1_type=3D"virtio-blk" disk1_name=3D"disk1.img" #disk2_type=3D"nvme" disk2_type=3D"virtio-blk" disk2_name=3D"disk2.img" disk3_type=3D"ahci-cd" disk3_dev=3D"custom" disk3_name=3D"/vm/.iso/virtio-win.iso # windows expects the host to expose localtime by default, not UTC utctime=3D"no" uuid=3D"291ee834-f125-11ec-8580-d05099d1a548" network0_mac=3D"#################" #---------------------------------------------- Regards Duncan --=20 You are receiving this mail because: You are the assignee for the bug.=
