RE: Watchdog for reboot VM when it's broken(no respond).
Hello, finally I installed wachtdog in my VM. I have Linux Ubuntu there.
I used xen_wdt module in watchdog.
It is whatchdog configuration:
"/etc/default/watchdog"
# Start watchdog at boot time? 0 or 1 run_watchdog=1 # Start wd_keepalive after stopping watchdog? 0 or 1 run_wd_keepalive=1 # Load module before starting watchdog watchdog_module="xen_wdt" # Specify additional watchdog options here (see manpage)./etc/watchdog.conf
#ping = 8.8.8.8 ping = 192.16.171.254 interface = eth0 file = /var/log/syslog 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 #allocatable-memory = 1 #repair-binary = /usr/sbin/repair #repair-timeout = 60 #test-binary = #test-timeout = 60 # The retry-timeout and repair limit are used to handle errors in a more robust # manner. Errors must persist for longer than retry-timeout to action a repair # or reboot, and if repair-maximum attempts are made without the test passing a # reboot is initiated anyway. #retry-timeout = 60 #repair-maximum = 1 watchdog-device = /dev/watchdog # Defaults compiled into the binary #temperature-sensor = #max-temperature = 90 # Defaults compiled into the binary admin = root interval = 20 logtick = 1 log-dir = /var/log/watchdog # This greatly decreases the chance that watchdog won't be scheduled before # your machine is really loaded realtime = yes priority = 1 # Check if rsyslogd is still running by enabling the following line #pidfile = /var/run/rsyslogd.pidI broke my SO and watchdog reset my vm.
I wait help with this.

XCP on intel i9 12th or 13th generation
Hello everyone.
I thing buy a new CPU for use with xcp-ng, but I have a doubts about how XCP works with Hybrid CPUs (P-Cores and E-Cores) .
Ej. xcp use all Cores or only P-Cores? How xcp works with the VMs and P-Cores and E-Cores
How xcp works with the VMs and P-Core and E-Core?

RE: Watchdog for reboot VM when it's broken(no respond).
@ravenet This is the /var/log/xensource.log when I test watchdog until VM starts again on the vm ID:1938f572-4951-a77f-48ce-9131c07940d4
Can you understand this process with the log?
Can you help me understand?

RE: Watchdog for reboot VM when it's broken(no respond).
Hello, finally I installed wachtdog in my VM. I have Linux Ubuntu there.
I used xen_wdt module in watchdog.
It is whatchdog configuration:
"/etc/default/watchdog"
# Start watchdog at boot time? 0 or 1 run_watchdog=1 # Start wd_keepalive after stopping watchdog? 0 or 1 run_wd_keepalive=1 # Load module before starting watchdog watchdog_module="xen_wdt" # Specify additional watchdog options here (see manpage)./etc/watchdog.conf
#ping = 8.8.8.8 ping = 192.16.171.254 interface = eth0 file = /var/log/syslog 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 #allocatable-memory = 1 #repair-binary = /usr/sbin/repair #repair-timeout = 60 #test-binary = #test-timeout = 60 # The retry-timeout and repair limit are used to handle errors in a more robust # manner. Errors must persist for longer than retry-timeout to action a repair # or reboot, and if repair-maximum attempts are made without the test passing a # reboot is initiated anyway. #retry-timeout = 60 #repair-maximum = 1 watchdog-device = /dev/watchdog # Defaults compiled into the binary #temperature-sensor = #max-temperature = 90 # Defaults compiled into the binary admin = root interval = 20 logtick = 1 log-dir = /var/log/watchdog # This greatly decreases the chance that watchdog won't be scheduled before # your machine is really loaded realtime = yes priority = 1 # Check if rsyslogd is still running by enabling the following line #pidfile = /var/run/rsyslogd.pidI broke my SO and watchdog reset my vm.
I wait help with this.
