Necessary Virtuozzo updates have not been installed or SVE was not upgraded after updates installation.Resolution
To resolve the issue you should apply the latest updates for Virtuozzo 3.0.0 and to make sure that VZAgent packages installed on SVE have the same versions as packages on the node itself. VZAgent version should be at least 3.0.0-12.4.WARNING: Do not upgrade Virtuozzo to the next major version (e.g. to 4.0.0), as of version 2.7, POA does not support VZ 4.0.0 yet.
Please see the following article about keeping Virtuozzo up to date:
{kb1170}
To compare VZAgent versions installed on SVE/node use the following commands (execute on the VZ harware node):
# rpm -qa | grep vzagent
vzagent-libsystem-3.0.0-12.5.swsoft
vzagent-lib-3.0.0-12.5.swsoft
vzagent-opcontrol-3.0.0-12.5.swsoft
vzagent-plugins-3.0.0-12.5.swsoft
# vzctl exec 1 "rpm -qa | grep vzagent"
vzagent-lib-3.0.0-12.5.swsoft
vzagent-libsystem-3.0.0-12.5.swsoft
vzagent-srvcontrol-3.0.0-12.5.swsoft
In case the versions are different, you should update SVE up to the current version which is installed on the hardware node. If you updated Virtuozzo using vzup2date utility, SVE can be upgraded this way:
# for i in `find /vz/vzup2date/3.0.0/ -type d -name TU* | sort -t- -k3 -n`; do vzsveupgrade -d $i; done{kb1089}
Once you have updated VZAgent, resubmit the failed task - it should complete successfully.
