You know, you are very lucky. We do face issues from time to time when
processes die after online migration and
the root cause appears in cpus difference.
I wonder, is there some way to override the paranoia? Ideally, an admin could
say "yes, I understand the CPUs aren't identical, but do it anyway"
Here you are:
# man vzmigrate
-f,
--nodeps[=[all][,cpu_check][,disk_space][,technologies][,license][,rate][,bindmount][,tem‐
plate_area_sync][,kernel_modules]]
Ignore an absence of required package sets on destination node.
To prevent CT against errors
in filesystem due to absent template files, it will not be
started on destination node after
migration and must be started manually.
Additional parameters:
all - as is -f.
cpu_check - to pass check of the cpu capabilities.
