Hello,
the problem I describe below has to do with a FreeBSD Virtual Machine running 10.1-RELEASE-p29 (build from source). The hypervisor is KVM (Proxmox VE 3.4).
This is a test of looking if I could get the following to work:
The rc.conf of this VM is:
The ZPOOL, called sctest, is healthy:
The commands used to create the test jail are:
So far so good. But when I start this jail with the command
Can anyone tell from the above what causes this? Did I something wrong? I know that VIMAGE/VNET is still experimental in 10.x but users are using it. It is on the reoadmap for 11 to make it stable and fix all the issues. But I would like to test this now.
Thank you in advance for any feedback.
Regards,
Lars.
the problem I describe below has to do with a FreeBSD Virtual Machine running 10.1-RELEASE-p29 (build from source). The hypervisor is KVM (Proxmox VE 3.4).
This is a test of looking if I could get the following to work:
- have a ZFS ZPOOL
- for running jails with VIMAGE/VNET functionality
- using the iocage package to provision and manage the jails

sudo iocage start jailtest the VM crashes because of a kernel panic. The information from the /var/log/messages:
