Guest crash when host `service alsasound restart`

Postby mvyver » 25. Jun 2009, 09:25

I see what appears to be the same behavior with VB 3.0.0 beta2 as reported in this old bug report for v 1.3.8 -> 2.2.4:
http://www.virtualbox.org/ticket/277

Specifically the guest OS (WinXP) crashes when, on the host (openSUSE 11.1) I run:
Code: Select all   Expand viewCollapse view
# service alsasound restart


The VB.log is attached as is the strace for VB 3.0.0, see the bug report for a 2.2.4 strace of the same behavior.

I am skeptical of the claim by franks in that bug report "VirtualBox does not change any sound-related files on installation. "
I still have no sound after installing VB 2.2.4 and running:
Code: Select all   Expand viewCollapse view
# /etc/init.d/vboxdrv setup


Under both VB 2.2.4 and 3.0.0beta2 the guest will always crash if I run
Code: Select all   Expand viewCollapse view
# service alsasound restart


The forum won't allow the file to be uploaded so I will upload the file under the bug report mentioned before. I attach the strace log from:
Code: Select all   Expand viewCollapse view
> VirtualBox &
> sudo strace -f -o /tmp/strace.log -p <pid>
(start guest OS (WinXP)
# sudo service alsasound restart


Appreciate any suggestions, and any love for the old bug report :)

This is not a bug of VirtualBox. Please have a look at the script in /etc/init.d/alsasound. The terminate function will kill all processes holding open sound devices. Of course we could catch the SIGKILL but I would rather say that either you should not restart the sound system while a VM is running our openSUSE should check the script.
