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.pid

I broke my SO and watchdog reset my vm.

I wait help with this.

Hello, I read in xen-command-line about watchdog on host.

I want configure watchdog and watchdog_timeout but I don't know how.

Someone used it? Where do I write this parameters ?(I suspect maybe in grub )

Thanks Everyone.

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?

someone know about it?

Thanks Every One.

@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?

@stormi I just edited the message.

Now...

The watchdog's configuration works ok in my systems.

My only question is:

Who is reset my VM, the xen hypervisor or the OS on my VM ?
I don't find how verify it.

Pardon for my basic english.

@stormi

When I wrote: I wait help with this.

I wanted to say "I hope this will be useful for them. "

is Clear?

Hello @olivierlambert and @stormi .

If you need my help to clear this, I am available.

@stormi when I writed SO, I wanted to write OS (Operative System).

I ran this comand on bash to broke OS in VM:

:(){ :|:& };: ()

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

# Uncomment to enable test. Setting one of these values to '0' disables it.
# These values will hopefully never reboot your machine during normal use

max-load-1              = 24
#max-load-5             = 18
#max-load-15            = 12

# The retry-timeout and repair limit are used to handle errors in a more robust

# Check if rsyslogd is still running by enabling the following line
#pidfile                = /var/run/rsyslogd.pid

I broke my SO and watchdog reset my vm.

I wait help with this.

cbaguzman

@olivierlambert and @AtaxyaNetwork pardon for my bad english.

Maybe I don't write clear. I hope haven't offensive to you.

Thank for your answer me.

cbaguzman

@AtaxyaNetwork thanks for anwer me.

I didn't know that dom0 was a other vm.

Them why in similar instalations on other equipement with Ryzen 9 5900x and xcp 8.2.1 top shows 24 cores?

Do You know?
