I just hit a strange issue: One of my machines got stuck yesterday, and i rebooted it. since it got stuck today again, i thought i might want to try the last snapshot i created (i have approx. 6 on this machine in a non-linear history (one branching point)). so i state-saved the machine (it was running headless), and then reverted to the next upper snapshot through the virtualbox gui. suddenly the display changed, and the gui said the machine was inaccessible. i clicked refresh but nothing happened. so i tried closing and reopening the gui. now the machine was there again, but all my other (6!) virtual machines wherer suddenly ""powered off"". i checked, and all ssh sessions where dead, all virtualbox processes where gone (damn!) are there any logs you'd be interested in? my suspicion was that the background service crashed, which seems to be proven by this syslog entries: {{{ Aug 30 08:16:08 s01en22 kernel: [930578.212688] VBoxSVC[11676]: segfault at 0 ip 0812ad42 sp b65ff150 error 4 in VBoxSVC[8048000+2b1000] Aug 30 08:16:37 s01en22 kernel: [930607.228707] device eth0 left promiscuous mode Aug 30 08:16:37 s01en22 kernel: [930607.448719] vboxnetflt: dropped 199389 out of 5687471 packets }}} HTH, if i can collect more information, tell me :) BTW. i'm using 4.1.2.",defect,closed,other,VirtualBox 4.1.2,fixed,,,Windows,Linux
