나는 한동안 Google에서 이것을 검색해 왔지만 아직 내 6300esb 감시 타이머용 커널 드라이버를 /dev/watchdog에 연결하고 감시 데몬이 이를 활성 상태로 유지하는지 확인하는 방법에 대한 적절한 문서를 찾지 못했습니다.
그런데 KVM 가상 머신에서 RHEL 호환 Scientific Linux 6.3을 사용하고 있습니다.
아래는 지금까지 시도한 모든 것입니다.
dmesg|grep 6300
i6300ESB timer: Intel 6300ESB WatchDog Timer Driver v0.04
i6300ESB timer: initialized (0xffffc900008b8000). heartbeat=30 sec (nowayout=0)

ll /dev/watchdog
crw-rw----. 1 root root 10, 130 Sep 22 22:25 /dev/watchdog

/etc/watchdog.conf
#ping = 172.31.14.1
#ping = 172.26.1.255
#interface = eth0
file = /var/log/messages
#change = 1407
# Uncomment to enable test. Setting one of these values to '0' disables it.
# These values will hopefully never reboot your machine during normal use
# (if your machine is really hung, the loadavg will go much higher than 25)
max-load-1 = 24
max-load-5 = 18
max-load-15 = 12
# Note that this is the number of pages!
# To get the real size, check how large the pagesize is on your machine.
#min-memory = 1
#repair-binary = /usr/sbin/repair
#test-binary =
#test-timeout =
watchdog-device = /dev/watchdog
# Defaults compiled into the binary
#temperature-device =
#max-temperature = 120
# Defaults compiled into the binary
#admin = root
interval = 10
#logtick = 1
# This greatly decreases the chance that watchdog won't be scheduled before
# your machine is really loaded
realtime = yes
priority = 1
# Check if syslogd is still running by enabling the following line
#pidfile = /var/run/syslogd.pid
지금은 올바르게 테스트하고 있지 않을 수도 있지만 watchdog 서비스를 중지하면 /dev/watchdog이 30초 후에 시간 초과되고 호스트 재부팅이 표시되어야 하지만 이는 발생하지 않을 것으로 예상됩니다.
또한 KVM vm에 대한 구성은 다음과 같습니다.

내가 찾은 대부분의 패치는 kvm 및 일반 소프트독 문서 또는 IPMI 감시 응답에 대한 패치이므로 도움을 주시면 감사하겠습니다.
