Hi, I'm trying to setup a virtual lab to test the heartbeat cluster software. I've setup 4 uml hosts, connected via uml_switch and one using also tuntap interface to work as gateway to the external network. I'm using a Fedora 7 image from nagafix. Everything seems to work fine, cow files, network, package installation, and even heartbeat startup. But everytime a I try to add "group service" to the ha cluster, on of the virtual hosts just crash with a kernel panic.

If I try all these setups on a x86 hosts, the problem seems to disapear. Any ideas ? ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc. Still grepping through log files to find problems? Stop.
