Is there anything under /zones/<vm uuid>/cores for the particular virtual machine?

If the crash/BSOD originates from the virtio disk driver, then there may not be anywhere to write crash information to. It might be worth setting Windows to not restart on BSOD, which can be done through Control Panel -> System and Security (System if small icons) -> Advanced System Settings -> Startup and Recovery and uncheck ‘Automatically restart’. Unfortunately you would be sacrificing the auto-restart feature but when you next notice the box is down you should be able to jump on VNC and see what the error condition was. If Windows is just BSOD’ing and rebooting within the VM itself then the qemu processes won’t exit so the vm.log output is probably correct. The only time this would be different is if Windows isn’t actually crashing, but qemu is, but that would require a vmadm start <uuid> to get it going again.

There is no apparent reason with about 100GB free in the pools and no entries in the windows system log other than it restarted for unknown reasons. the vm.log just shows the boot process, the previous logs are all empty. We did use virtio drivers from january and did switch back to stable from dezember in case that causes issues. But i am not sure how a driver failure could initiate a full reboot without leaving a bluescreen dump. did anybody solve this or track this down further ? thanks, Matthias On Wed, Jul 23, 2014 at 6:34 PM, Mark Creamer via smartos-discuss <[email protected]<mailto:[email protected]>> wrote: Hi, I have a Windows 2008 R2 KVM that crashes constantly. There is nothing in the system log, except after it comes up there is the usual "previous shutdown was unexpected." There is no bluescreen (bugcheck) recorded. None of my other KVMs are having the same issue, and this one is a problem on both the original host I built it on, and another host I moved it to. While I'm troubleshooting further, is there an updated driver for the virtual disk? I'm not sure where to locate that and I thought I might try that next.
