VServer stop fails to stop the virtual machine if the script that
does the stop contains commands that work in the network context
of the virtual machine.
The problem is serious because the natural use of VServer are server
processes. Often, they cannot be cleanly shutdown. In particular, this
bug affects the shutdown of any Java server, because the shutdown of
these servers happens by sending a packet to a certain port. Tomcat is
affected by this issue.
The fix is simple. Someone just forgot to run the shutdown command
in the context of the virtual machine.
In the script vserver.stop replace:
elif $_VSERVER_INFO - FEATURE migrate; then
"[EMAIL PROTECTED]" \
${USE_VNAMESPACE:+$_VNAMESPACE --enter "$S_CONTEXT" -- } \
$_VCONTEXT $SILENT_OPT --migrate --chroot --xid "$S_CONTEXT" -- \
"[EMAIL PROTECTED]" || fail=1
else
by
elif $_VSERVER_INFO - FEATURE migrate; then
"[EMAIL PROTECTED]" \
"$_CHBIND" "[EMAIL PROTECTED]" \
${USE_VNAMESPACE:+$_VNAMESPACE --enter "$S_CONTEXT" -- } \
$_VCONTEXT $SILENT_OPT --migrate --chroot --xid "$S_CONTEXT" -- \
"[EMAIL PROTECTED]" || fail=1
The missing chbind command is what prevents the vserver stop command
from running commands in the network context of the virtual machine.
The issue has been reported to the developer of vserver utils. See
http://savannah.nongnu.org/bugs/?func=detailitem&item_id=20475
and it has been fixed in the latest release.
