That's the problem! I guess the website you've got the executable kernel image, doesn't release the kernel modules too. I think you should make your own kernel image from your own sources (you can get them at kernel.org) and make your modules. It's almost easy.

[uml-user] UML reboot and freeing ports
All, I've noticed that when a UML reboots it will not free any port it was using, and open another one. Case in point: when using vde_switch. Connect a UML to vde_switch using something like: # vde_switch -s /tmp/switch1 # linux ubda=cow1,myfs umid=uml1 eth0=tuntap,tap0 eth1=vde,/tmp/switch1 In vde_switch use 'port/print' to see which PID is using which port. reboot the UML. Go back to vde_switch and now there are two ports for the same PID. Shutdown the UML and in vde_switch the PID is not there anymore. Has anyone come up with a fix regarding this ? It looks like UML should release the resource when rebooting and then use another one. Or keep the resource and not use another one. Any thoughts on this appreciated. -- Open Source Business Conference (OSBC), March 24-25, 2009, San Francisco, CA -OSBC tackles the biggest issue in open source: Open Sourcing the Enterprise -Strategies to boost innovation and cut costs with open source participation -Receive a $600 discount off the registration fee with the source code: SFAD http://p.sf.net/sfu/XcvMzF8H ___ User-mode-linux-user mailing list User-mode-linux-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/user-mode-linux-user
[uml-user] Host files opened multiple times by UML
Has anyone seen this before? 1. I do an "lsof | wc" on my host and get about 2.3K files (normal for a workstation) 2. I startup UML . In my UML instance and get 2.8K (again normal) 3. When I do an lsof on the host again I get 24K files. 4. My uml is running hostfs and it looks like it is opening all the right files but just opening them multiple times. For example one my libraries is libalp_flightmodeui.so a. On the UML instance: # lsof | grep libalp_flightmodeui.so bar:com.a 1040 com.access.statusbarmgr.2 mem REG 0,12 571936734127 /opt/alp/lib/libalp_flightmodeui.so b. On the host (the host does not open libalp_flightmode ui for any reason other than UML) svdmoffattlnx:~$ lsof | grep /libalp_flightmodeui.so alp-linux 12572 david 352r REG8,7 57193 6734127 /home/scratchbox/users/david/targets/alp-x86-dbg-dev/opt/alp/lib/libalp_ flightmodeui.so alp-linux 12582 david 352r REG8,7 57193 6734127 /home/scratchbox/users/david/targets/alp-x86-dbg-dev/opt/alp/lib/libalp_ flightmodeui.so [repeats removed] c. Also on the host svdmoffattlnx:~$ lsof | grep /libalp_flightmodeui.so | wc 59 5319440 The only thing that I am doing odd is I don't use the SKAS patches. --Thanks for any ideas David Moffatt -- Open Source Business Conference (OSBC), March 24-25, 2009, San Francisco, CA -OSBC tackles the biggest issue in open source: Open Sourcing the Enterprise -Strategies to boost innovation and cut costs with open source participation -Receive a $600 discount off the registration fee with the source code: SFAD http://p.sf.net/sfu/XcvMzF8H___ User-mode-linux-user mailing list User-mode-linux-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/user-mode-linux-user
