Hi, Recently I updated my openSuse box from 12.3 to 13.1. On this box I run xen with several guests. One of these guests is an appliance that has 4 kvm guests running. When I start this appliance with the nested vmx feature the appliance crashes either immediately or after a few minutes. This same guest was running without a problem on opensuse releases 11.4 until 12.3 ( remark that about 3 year ago some patches were written by tim degan to make this appliance work ), I am not 100% sure what the right list to post this is soI also posted this problem on the xen-devel list. dom0 opensuse 13.1 x86 kernel 3.11.10-21-xen xen: 4.3..2_01-21.1 - domu (HVM) - sles11sp2 - mem: 8 GB - vcpu: 4 - kvm with 4 guest any body any thought on this?
