Not able to access VZPP (Virtuozzo Power Panel) for a VE.

Resolution

Make sure that “offline management” for the VE is enabled:

# grep OFFLINE_MANAGEMENT /etc/sysconfig/vz-scripts/VE_ID.conf
OFFLINE_MANAGEMENT="yes"

If “offline management”  is disabled (set to “no”), you have to enable it:

# vzctl set VE_ID --offline_management yes --save
