There doesn't seem to be anything in the VBox.log that indicates the |
| 2 |
system had a hard lockup. I imagine the kernel panicing resulted in |
| 3 |
VirtualBox being unable to write to the log. |
| 4 |
|
| 5 |
Is anyone running VB on a Linux raid partition? I've logically |
| 6 |
narrowed down the issue to one of the following: |
| 7 |
|
| 8 |
(a) I've read that network driver(s) have caused some hard lockups on |
| 9 |
the host...I'm using bridged mode |
| 10 |
(b) there are some strange messages that appear when the VM is started |
| 11 |
(regarding misaligned sectors or something like that); I can't seem to |
| 12 |
find the messages right now, however. I believe md was the one logging |
| 13 |
the errors; maybe this has something to do with the hard lockup? |
| 14 |
(c) SMP has probably been ruled out; I have two 4-core Intel 5570s; |
| 15 |
the system is under no load whatsoever. In fact, the last two kernel |
| 16 |
panics occurred during Windows installation. |
| 17 |
|
| 18 |
Any other thoughts on how to troubleshoot this? |
