Domu-u Zwis Na Udev

[krupek]

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

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)

to jest xend.log z Dom-0

 

 

[Gość _PaT]

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.

Sorki ze dopiero teraz straszny miałem nawal roboty co nie rozwiązało problemu:

nie mam hda mam

fdisk -l /dev/xvda z dom-U

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.
