OpenSolaris Kernel Dump

[drseek]

I'm running VirtualBox 2.1.4 on OpenSolaris 101b. The guest OS is Windows XP SP3. Every time I shut down the guest OpenSolaris crashes. Maybe the cause is the same as described in ticket #2705 but I'm using an actual OpenSolaris and VirtualBox build.

The logs (/var/adm/messages and VirtualBox log) are appended to the ticket.

Here is the SCAT output of the crash:

Have you tried using NAT instead of Host Interface networking to see if it prevents the crash?

Also could please you show output of ifconfig -a from the host?

[drseek]

I tried NAT but crashes again.

Here is the output of ifconfig -a:

lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
	inet 127.0.0.1 netmask ff000000

At the moment the Windows guest doesn't have access to the internet.

Replying to drseek:

I tried NAT but crashes again.

Could you please attach log file of crash with NAT, if possible core file.

# ulimit -c unlimited
# VirtualBox -startvm [name of your VM]

[vasily Levchenko]

Could you please attach log file of crash with NAT, if possible core file.

If core file available we would provide information where it could be uploaded (please contact me vasily.levchenko [at] sun [dot] com)

[drseek]

I attached the log file of crash.

Before the crash occured I leaved the full screen mode of the guest, switch to firefox on the host and browse variouse webpages and suddenly the system crashes. At that time the guest was running in the background.

[drseek]

Guest with enabled NAT.

[James McPherson]

For submitter - could you turn on kmem_flags in /etc/system please:

set kmem_flags=0xf

regenerate your boot archive and then reboot.

Also, if you can supply the actual crash dump files (or a pointer to them) from your host that would be handy.

Finally, are you using a fixed size backing store, or expanding? (Not that I think it matters, but it's always better to have a full picture of the configuration).

[Frank Mehnert]

drseek, please could you check if VirtualBox 2.2.2 changes anything for you and if not, read jmcp's advises?

[Ramshankar Venkataraman]

Please re-open if problem still persists.
