I found the following info in the UML Wiki troubleshooting section, hope it can help... Ginie Q: My uml guest hangs when doing large disk I/O such as untarring files or installing packages. One way that UML can be slow is if you have CONFIG_BLK_DEV_UBD_SYNC set in your uml kernel. This will cause syncs to block the uml instance until they complete, resulting in long pauses. Disabling it in your kernel config will speed up your uml instance significantly. If you change, in the UML command line, things like "ubd0=file1 ubd1=file2" to "ubd0s=file1 ubd1s=file2", you will get again the same safety, without the big slowdown caused by CONFIG_BLK_DEV_UBD_SYNC. More info on this can be found in these two threads (especially the second): http://marc.theaimsgroup.com/?l=user-mode-linux-user&m=107022862505588&w=2 http://marc.theaimsgroup.com/?l=user-mode-linux-user&w=2&r=1&s=bonnie+almost&q=b __________________________________ Celebrate Yahoo!'s 10th Birthday!
