id summary reporter owner description type status component version resolution keywords cc guest host 6940 VM started with VBoxHeadless hangs occasionally Freek de Kruijf "I have an openSUSE 11.1 host system using VirtualBox 3.1.6. I have an openSUSE 11.1 guest. I run a cron job in the night on the host which stops the guest and it waits for the guest to be completely stopped. The cron jobs does its other work for about 45 minutes. After that the cron job starts the VM using the command: {{{ VBoxManage startvm ktmh01 -type vrdp >> 00to02.log 2>/dev/null }}} Occasionally after this the cron job waits indefinitely for this command to finish. I have to stop VBoxHeadless using {{{ kill -9 }}} Lately this happened on June 1st and June 8th. After killing VBoxHeadless I can start the VM using the same command and it works perfectly. I will prepare the cron job to enable the possibility to make a coredump when the the VM hangs again. However {{{ sudo echo -n 1 > /proc/sys/fs/suid_dumpable }}} does not work, not even in console mode, but i will find a way to have a 1 in /proc/sys/fs/suid_dumpable when the VM is started and do a {{{ ulimit -c unlimited }}} before the VBoxManage command.
