To simplify Kdump configuration, support for the
crashkernel=auto
kernel parameter was
enabled in UEK R3 Quarterly Update 1.
Xen does not support the crashkernel=auto
parameter.
If the crashkernel=auto
parameter is
enabled, the output of the dmesg command
shows crashkernel=XM@0M
. This is normal.
When configuring a crashkernel
setting
for the UEK prior to UEK R3 Quarterly Update 1, using the
crashkernel=auto
parameter causes Kdump
to fail to start. Only standard settings such as
crashkernel=128M@32M
are supported.
