[Xen-devel] Enabling kdump on SuSE 11 SP3 Xen resulting in error

[Saurabh Mishra <saurabh.globe@xxxxxxxxx>]

Hi,

I'm trying to enable kdump on SuSE 11 SP3 with Xen configuration on our cards but having problem.

If I don't specify KDUMP_DUMPFORMAT=ELF, it does not work and does not try to take vmcore.

If I specify KDUMP_DUMPLEVEL=0, then it does work but it takes very long time. I tried using KDUMP_DUMPLEVEL=30 or 10 but it complaint that there is not much space even though I've about 4.8 GB space with crashkernel configured as 256M@64M. Here's output from /proc/cmdline :-

lc-1:~ # cat /proc/cmdline 

crashkernel=256M@64M root=/dev/sda5 earlyprintk=serial,ttyS0,115200n8 resume=/dev/sda5 splash=silent showopts  console=ttyS0,115200n8
