Creating a kernel dump of a KVM guest
A dump of a KVM guest can be driven by the host or by the guest.
Guest-driven dumps
You can set up kdump to create a kernel dump for an instance of Linux® as a KVM guest on IBM® Z. With kdump in place, a dump is triggered automatically by a kernel panic.
Alternatively, you can use the zgetdump command to create a live-system
dump.
See the kdump information in Using the Dump Tools, SC33-8412.
Host-driven dumps
The KVM virtual server administrator can initiate dumps of KVM guests. See the section about dumping KVM guests in KVM Virtual Server Management, SC34-2752.
