[Bug 564093] New: xend doesn't create bridge during boot after update 11.1 to 11.2
http://bugzilla.novell.com/show_bug.cgi?id=564093 http://bugzilla.novell.com/show_bug.cgi?id=564093#c0 Summary: xend doesn't create bridge during boot after update 11.1 to 11.2 Classification: openSUSE Product: openSUSE 11.2 Version: Final Platform: x86-64 OS/Version: openSUSE 11.2 Status: NEW Severity: Normal Priority: P5 - None Component: Xen AssignedTo: jdouglas@novell.com ReportedBy: yury.buldakov@gmail.com QAContact: qa@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US) AppleWebKit/532.6 (KHTML, like Gecko) Chrome/4.0.267.0 Safari/532.6 After some investigation: On openSUSE 11.1 /dev/shm/sysconfig was created by /etc/sysconfig/network/scripts/functions.common:
# RUN_FILES_BASE contains the path to the configuration data cache. # It __must__ __not__ contain a trailing slash. RUN_FILES_BASE=/dev/shm/sysconfig test -d $RUN_FILES_BASE || mkdir -p $RUN_FILES_BASE xen bridge creation stores information then (/etc/xen/scripts/network-bridge): # Record creation of bridge in /dev/shm/sysconfig/xenbridges so other # tools, e.g. yast2 lan, know that Xen bridging is active. [ -d /dev/shm/sysconfig/xenbridges ] || mkdir /dev/shm/sysconfig/xenbridges touch /dev/shm/sysconfig/xenbridges/${bridge} But in openSUSE 11.2 RUN_FILES_BASE was changed: # RUN_FILES_BASE contains the path to the configuration data cache. # It __must__ __not__ contain a trailing slash. RUN_FILES_BASE=/dev/.sysconfig/network test -d $RUN_FILES_BASE || mkdir -p $RUN_FILES_BASE I was unable to find anything that takes care of creation '/dev/shm/sysconfig' directory used in '/etc/xen/scripts/network-bridge'

--- Comment #2 from Yury Buldakov
The /etc/xen/scripts/network-bridge script is not supposed to be used in openSUSE 11.1 or 11.2. All network management / bridge creation is done using `yast2 lan` or by manually modifying standard ifcfg files.
Yes, but in case of xen bridge creation is done inside of /etc/xen/scripts/network-bridge script
Are you using network-bridge on your system? Please post the output of the following command: grep -e "^(network-script" /etc/xen/xend-config.sxp
Yes, I'm using network-bridge on my system:
silentnoise:/etc/xen/scripts # grep -e "^(network-script" /etc/xen/xend-config.sxp (network-script network-bridge)
AFAIK network-bridge should take care of creating appropriate bridge device during rcxend start (it should rename eth0 -> peth0, create bridge eth0 and attach peth0 to it), but:

Yes, but in case of xen bridge creation is done inside of /etc/xen/scripts/network-bridge script
But we don't recommend using network-bridge any longer.
Yes, I'm using network-bridge on my system:
silentnoise:/etc/xen/scripts # grep -e "^(network-script" /etc/xen/xend-config.sxp (network-script network-bridge)
Edit /etc/xen/xend-config.sxp to disable it, e.g. (network-script )
AFAIK network-bridge should take care of creating appropriate bridge device during rcxend start (it should rename eth0 -> peth0, create bridge eth0 and attach peth0 to it), but:
Yes, but we don't want this behavior any longer. Using network-bridge breaks a lot of basic networking functionality, e.g. 'rcnetwork restart'.
Restarting xend (old pid 5822 5821) mkdir: cannot create directory `/dev/shm/sysconfig/xenbridges': No such file or directory
I fixed this bug but after 11.2 apparently. I'll make the change in that code base now in the event we do a maintenance update for 11.2.
After creating symlink /dev/shm/sysconfig -> /dev/.sysconfig/network:
The errors you got indicate mixing network-bridge with sysconfig managed bridge AFAICT. You need to disable network-bridge and ifup/ifdown scripts instead. Do you have a up/down script for a bridge? What is contents of /etc/sysconfig/network/ifcfg-* files? -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
