OpenSolaris 2008.11 System Panic

[Brian Leonard]

OpenSolaris 2008.11 is my host. I have 2 guests: Windows XP (NAT Networking) and Ubuntu (Host Interface Networking). I was saving the state of both guests when the panic occurred. Here's the information from messages.log:

I've also attached the log file for the Ubuntu virtual machine, as I suspect the host networking is probably more the culprit.

Ubuntu Log File

[Ramshankar Venkataraman]

There were several fixes to networking since this ticket, please re-try if you still have this problem.

[Brian Leonard]

Note, this issue is also being tracked at ​opensolaris.org. After further investigation, they recommend the following:

A (minor?) problem is that the error reporting is broken, the values rc and rc2 are printed as undefined values:

 Jan 28 14:24:50 opensolaris vboxdrv: [ID 402587 kern.notice] vboxflt:vboxNetFltSolarisAttachIp4: failed to get MuxFd from MuxId. rc=45 rc2=-675644024
 Jan 28 14:24:50 opensolaris vboxdrv: [ID 926875 kern.notice] vboxflt:vboxNetFltSolarisAttachIp6: failed to get MuxFd from MuxId. rc=45 rc2=-675644024

I think the following call in the vbox code should pass "rc" and "rc2" as arguments for the %d printf formats:

LogRel((DEVICE_NAME ":vboxNetFltSolarisAttachIp4: failed to get MuxFd from MuxId. rc=%d rc2=%d\n"));

This should be reported as a bug on www.virtualbox.org...

[Sander van Leeuwen]

This code is no longer present. Could you retry with 2.1.4?

[Ramshankar Venkataraman]

This should be fixed in 2.2.0 and above. Reopen if necessary.
