krupek Posted October 24, 2008 Report Share Posted October 24, 2008 Witam Zgłaszam się z bardzo nietypowym problemem. Podczas startu wirtualnego systemu CZASMI zwiesza podczas startu udev Dom-0 to CentOS5.2 Dom-U jest CentOS5.2 pracujący w trybie pełnej wirtualizacji(wiem wiem). Najlepsze jest że nie za każdym razem tak jest jak mi się zwiesi to robie xm destroy serwer1 i xm create serwer1 jeszcze raz zazwyczaj za którymś razem startuje poprawnie. Gdzie może być przyczyna takiego zachowania? Pozdrawiam Link to comment Share on other sites More sharing options...
Guest _PaT Posted October 24, 2008 Report Share Posted October 24, 2008 Wklej jakieś logi. Pewnie interesujące znajdą się w samej wirtualnej maszynie, ale na fizycznej też poszukaj. Przede wszystkim: - /var/log/messages - /var/log/xend/xend.log (wpisuję z pamięci, więc mogłem pomylić ścieżki) Link to comment Share on other sites More sharing options...

Guest _PaT Posted October 28, 2008 Report Share Posted October 28, 2008 Wygląda nieźle. Wklej jeszcze jak wygląda na dom0 /etc/xen/serwer1 (nie wiem czy tak nazwałeś plik - na pewno znajdziesz właściwy). Z domU wklej fdisk -l /dev/hda oraz /etc/fstab. Pewnie więcej informacji znajdziesz w dmesg domU. Link to comment Share on other sites More sharing options...

Guest _PaT Posted November 9, 2008 Report Share Posted November 9, 2008 Hmm, chyba wkleiłeś dane z innej maszyny niż wcześniej... Nie mniej jednak, jedyny interesujący nas fragment logów to: [2008-10-28 23:37:21 xend 3265] DEBUG (blkif:24) exception looking up device number for hda: [Errno 2] No such file or directory: '/dev/hda' Dlatego zapytałem o wycinki fstab i fdisk, ale te wyglądają ok. Google mówią na ten temat kilka ciekawych rzeczy. Nie będę jednak przepisywał - na pewno wygodniej będzie Ci korzystać z informacji z pierwszej ręki.
