this is just a warning indicating that vmstat within the guest tried to
access the hidden /proc/vmstat of the host. It can happen if you enter
the guest from the host and then run vmstat or ps etc.

You can disable these warnings by setting CONFIG_VSERVER_WARN=n in the
kernel config. Alternatively, if you don't want to disable all warnings
you can grep for the vxwprintk* functions, e.g. vxwprintk_task and
comment out specific / trivial warnings only.

Best regards,
John
