Resolution
To adjust default VE migration timeout directly in VZAgent configuration it is possible to edit the file /etc/sysconfig/vzagent/vzagent.conf file on Virtuozzo hardware node (in the section hwm/configuration/timeouts/migrate), by default it is set to 1 hour (3600 seconds):
<hwm><configuration>
<timeouts>
<migrate>3600</migrate>
To increase migration timeout it is required to increase value in <migrate> tag, just for example, to increase it up to 2 hours 3600 should be replaced with 7200.
Please note, VZAgent services restart is required to apply new VZAgent configuration in case of adjusting parameters directly in VZAGent configuration file. To restart VZAgent services the following command should be executed on Virtuozzo hardware node:
# vzagent_ctl restartKeywords: vzagent migration timeout
