First, thanks for ipmi_sim, it may be the key to virtualizing our clusters
for testing!
I'm running ipmi_sim against qemu+ipmi (from github). Sometimes, my
guests get stuck where they're unable to write to /dev/watchdog:
printf "\x00" > /dev/watchdog
-bash: printf: write error: Invalid argument
dmesg shows:
[ 421.514473] IPMI Watchdog: response: Error f0 on cmd 22
[ 421.515125] IPMI Watchdog: Unexpected close, not stopping watchdog!
[ 421.517388] IPMI Watchdog: response: Error f0 on cmd 22
Also, I've had to hack in a NULL test to avoid a segfault because the
watchdog sensor is not configured:
https://github.com/noelbk/openipmi/commit/ba895c75603b31bb15eccdfa98aafedbf8088496
Anything I can fix with a config?
Here's how I run ipmi_sim:
ipmi_sim -n -c ./ipmi1.conf -f ipmisim.emu &
and here's ipmisim.emu:
mc_setbmc 0x20
mc_add 0x20 0 no-device-sdrs 0x23 9 8 0x9f 0x1291 0xf02 persist_sdr
sel_enable 0x20 1000 0x0a
# Add a temperature sensor and its SDR. Note that sensor 0 is already
# taken as the watchdog sensor.
sensor_add 0x20 0 1 0x01 0x01
sensor_set_value 0x20 0 1 0x60 0
sensor_set_threshold 0x20 0 1 settable 111000 0xa0 0x90 0x70 00 00 00
sensor_set_event_support 0x20 0 1 enable scanning per-state \
000111111000000 000111111000000 \
000111111000000 000111111000000
# Turn on the BMC
mc_enable 0x20
I'm running about 12 instances of ipmi_sim on the same host with different
ips each attached to its own network interface.
Cheers,
