Need to get kernel dump or core dump from a virtual machine (domu)
Configure a SLES 10 or SLES11 vm for a vmcore
On the XEN host (dom0)
1. Modify the following line in /etc/xen/xend-config.xsp
4. Test the configuration:
- At a terminal prompt, shutdown corresponding vm if running and restart using
- xm create <vm name>
- Connect to the vm console by running xm console <vm name>& login as ROOT
- Run modprobe crasher call_panic=1
- Check /var/lib/xen/dump for the dump file
- As root user, from a terminal on XEN Host (dom0) run xm dump-core <vm name>
- Check /var/log/dump on the XEN Host (dom0)
Configure NetWare for a core dump
SLES 11 Host (unavailable for SLES 11 SP1 Host)
OES2 and Virtualized NetWare (NW65sp7 or later)
1. On Dom0 get, and install, the corresponding novell-nwcore rpm to facilitate coredumps on virtulized NetWare. Cliick below for current link:
OES2 and Virtualized NetWare (NW65sp7 or NW65sp8)
Install the correct rpm for SLES version and architecture as root user. Note that there will be two directories: One for SLES 10 SP1 and one for SLES10 SP2. Use the SLES 10 SP2 rpm's for SLES 10 SP2, SP3 and SLES 11 XEN hosts.
rpm -ivh novell-nwcore-1.0.4-1...
Managing the service:
Start ./etc/init.d/novell-nwcore start
Stop ./etc/init.d/novell-nwcore Stop
Status ./etc/init.d/novell-nwcore status
Default location for writing coredump:
If you wish to change the location of where the coredump is written, modify the /etc.init.d/novell-nwcore file and change the following:
1- Enter 386debug on the NetWare VM server console.
Check the directory specified in example above to make sure the .img file (coredump) was written.
Known Problems and Limitations:
Notes: The keyboard may be slow to respond to key strokes while in the debugger. The system may become unresponsive if the ++ keys are pressed prior to coredump process being completed.
