[OmniOS-discuss] Crashing qemu process

[Filip Marvan]

Hi Dan,

yes, you are right, I'm sorry.
Here are more detailed informations from core dump.

root at omnikvm:/# mdb core

I'm using freshly installed OmniOS r151012
Thank you for any help.

I have two virtual servers, one with Windows XP, which works without any problems, but the second one with Windows 2008 R2 server is crashing after some time. Qemu proces just crashed (after about one hour after VPS starts). There is nothing strange in /var/adm/messages, and i think that -d aption for debuging informations is not working (/tmp/qemu.log is empty even for -d exec for example).

Any qemu core files lying around?  Core dumps are the first thing to check, to see WHERE it crashed.
