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 )
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?
BR,
Jeroen
