Work log
2020-06-21: bvm4 - gets renamed to 'trap2' as part of the switch to vm-bhyve
root@kg-vm3# pwd
/zs/vms
root@kg-vm3# mv bvm4 trap2
add a config file
root@kg-vm3# more trap2/trap2.conf loader="bhyveload" cpu="1" memory="256M" network0_type="virtio-net" network0_switch="public" disk0_type="virtio-blk" disk0_name="guest-bvm4.img"
test it
root@kg-vm3# vm list NAME DATASTORE LOADER CPU MEMORY VNC AUTOSTART STATE trap2 default bhyveload 1 256M - No Running (10299) tv default bhyveload 2 1536M - No Running (9278) wiki default bhyveload 2 1024M - No Running (8672)
it works, and I can ssh into it
2019-11-27: vtbd0p3 - clock trouble
root@trap2# ntpq -p
remote refid st t when poll reach delay offset jitter
==============================================================================
kg-omni1.kg4.no 91.209.0.17 3 u 35 64 377 0.633 3592816 150966.
check
root@trap2# sysctl kern.timecounter.hardware kern.timecounter.hardware: TSC
change and verify
root@trap2# sysctl kern.timecounter.hardware=HPET
kern.timecounter.hardware: TSC -> HPET
root@trap2# sysctl kern.timecounter.hardware
kern.timecounter.hardware: HPET
ok.
2019-11-25: powered on after power outage.
2019-08-27: bvm4 - this machine has clock trouble too:
root@trap2# date;ntpq -p Sun Aug 25 21:58:29 CEST 2019 remote refid st t when poll reach delay offset jitter ============================================================================== kg-omni1.kg4.no 194.58.205.148 2 u 42 64 377 0.452 1256607 112735.
and the culprit is
root@trap2# sysctl kern.timecounter.hardware kern.timecounter.hardware: TSC
change
root@trap2# sysctl kern.timecounter.hardware=HPET
kern.timecounter.hardware: TSC -> HPET
fix time
root@trap2# service ntpd stop Stopping ntpd. root@trap2# ntpdate 10.1.10.1 27 Aug 08:55:53 ntpdate[27386]: step time server 10.1.10.1 offset 125700.424538 sec root@trap2# ntpdate 10.1.10.1 27 Aug 08:56:02 ntpdate[27387]: adjust time server 10.1.10.1 offset 0.000968 sec root@trap2# ntpdate 10.1.10.1 27 Aug 08:56:13 ntpdate[27388]: adjust time server 10.1.10.1 offset 0.000784 sec root@trap2# service ntpd start Starting ntpd.
and now?
root@trap2# date;ntpq -p Tue Aug 27 08:56:52 CEST 2019 remote refid st t when poll reach delay offset jitter ============================================================================== *kg-omni1.kg4.no 194.58.205.148 2 u 21 64 1 0.731 1.619 0.547
better.

ok.
2017-11-26: bvm4 - I modified /etc/motd and a few other files:
root@trap2:~ # more /etc/ntp.conf server 10.1.10.1 iburst
and /etc/dhclient.conf
root@trap2# tail -1 /etc/dhclient.conf send dhcp-client-identifier "trap.kg4.no";
change sh for root
root@trap2:~ # chsh -s /bin/sh
chsh: user information updated
I also fixed a few more files, mainly for convenience.
2017-11-26: vm3 - tmux - list (active sessions)
root@kg-vm3# tmux ls bhyve_bvm1: 1 windows (created Mon Oct 16 18:49:41 2017) [80x24] bhyve_bvm2: 1 windows (created Mon Oct 16 18:49:42 2017) [80x24] bhyve_bvm3: 1 windows (created Mon Oct 16 18:49:42 2017) [80x24] bhyve_bvm4: 1 windows (created Sun Nov 26 19:45:37 2017) [106x52]
connect to bvm4
root@kg-vm3# tmux attach -t bhyve_bvm4
(and the session starts)
2017-11-26: vm3 - bhyve - set up the new machine (1 cpu, 256M, 4 G, tap3)
create a directory for it
root@kg-vm3# cd /zs/vms
root@kg-vm3# mkdir bvm4
make file for a virtual disk drive
root@kg-vm3# truncate -s 4G bvm4/guest-bvm4.img root@kg-vm3# ls -lh bvm4 total 96 -rw-r--r-- 1 root wheel 4.0G Nov 26 19:18 guest-bvm4.img
install the machine
root@kg-vm3# sh /usr/share/examples/bhyve/vmrun.sh -c 2 -t tap3 -d /zs/vms/bvm4/guest-bvm4.img -i -I /zs/tingo/dl/bsd/FreeBSD-10.4-RELEASE-amd64-disc1.iso bhyve_bvm4
this boot and starts the install. Selection and changes: xterm, Install, Norwegian ISO-8859-1 keymap, trap2.kg4.no, unselect games, lib32, ports, disk guided, entire disk, gpt, modify so I get 1G swap, 3G rootfs, net dhcp, services sshd, ntpd, dumpdev, set timezone. On exit, it reboots, just select "reboot" from the boot menu.
I add bvm4 to /etc/rc.conf.local:
root@kg-vm3# grep bvm4 /etc/rc.conf.local bhyve_profiles="bvm1 bvm2 bvm3 bvm4" bhyve_bvm4_tapdev="tap3" bhyve_bvm4_diskdev="/zs/vms/bvm4/guest-bvm4.img" bhyve_bvm4_ncpu="1" bhyve_bvm4_memsize="256"
check bhyve status
root@kg-vm3# service bhyve status ===> bhyve profile: bvm1 bhyve_bvm1 is running. ===> bhyve profile: bvm2 bhyve_bvm2 is running. ===> bhyve profile: bvm3 bhyve_bvm3 is running. ===> bhyve profile: bvm4 bhyve_bvm4 is not running.
start bvm4
root@kg-vm3# service bhyve start bvm4
Starting bhyve.
root@kg-vm3# service bhyve status ===> bhyve profile: bvm1 bhyve_bvm1 is running. ===> bhyve profile: bvm2 bhyve_bvm2 is running. ===> bhyve profile: bvm3 bhyve_bvm3 is running. ===> bhyve profile: bvm4 bhyve_bvm4 is running.
ok.
2017-11-26: setting up a new loginhost, so I can take vbox-trap offline. Trying to move everything off the VirtualBox host.
